What Does a Jockey Pump Actually Do in a Fire Protection System?

 



Fire protection systems are designed to respond immediately when an emergency occurs. While the fire pump often gets the most attention, another component works quietly behind the scenes every day to keep the system ready. That component is the jockey pump.

Many building owners and facility managers assume a jockey pump is simply a smaller version of the main fire pump. In reality, it serves a completely different purpose. Without it, even minor pressure changes in the sprinkler system could trigger unnecessary operation of the fire pump, leading to increased wear, maintenance costs, and reduced equipment life.

In this guide, we'll explain what a jockey pump does, why it matters, and how it supports the overall reliability of your fire protection system.

What Is a Jockey Pump?

A jockey pump is a small pressure maintenance pump installed within a fire protection system. Its primary job is to maintain the system's water pressure by compensating for minor pressure losses caused by temperature fluctuations, small leaks, valve seepage, or routine testing.

Unlike the main fire pump, a jockey pump is not designed to supply water during a fire. Instead, it ensures the system remains pressurized so the main fire pump only starts during an actual emergency.

Why Is a Jockey Pump Important?

Fire sprinkler systems must remain pressurized around the clock. Even a slight pressure drop can cause the fire pump controller to interpret the change as a demand for water.

Without a jockey pump, the main fire pump may start repeatedly due to insignificant pressure variations. Frequent cycling can result in:

  • Increased wear on the fire pump
  • Higher maintenance costs
  • Greater energy consumption
  • Reduced equipment lifespan
  • Unnecessary operational disruptions

A jockey pump prevents these issues by restoring pressure before the main fire pump needs to activate.

How Does a Jockey Pump Work?

The operation of a jockey pump is straightforward yet highly effective.

Here's the process:

  1. The fire protection system remains fully pressurized.
  2. A minor pressure drop occurs because of a small leak or temperature change.
  3. Pressure switches detect the reduction.
  4. The jockey pump starts automatically.
  5. It restores the system to its preset pressure.
  6. Once the desired pressure is reached, the jockey pump shuts off.

If a sprinkler head opens during an actual fire, the pressure drops much more rapidly than the jockey pump can recover. At that point, the fire pump controller activates the main fire pump to provide the required water flow.

Jockey Pump vs Fire Pump

Although they work together, these pumps serve very different purposes.

Jockey PumpFire Pump
Maintains system pressureSupplies high water flow during a fire
Small motor and lower flow rateLarge motor with high flow capacity
Operates frequently for minor pressure changesOperates only during fire conditions or testing
Prevents unnecessary fire pump startsDelivers water to sprinklers and standpipes

Understanding this distinction helps facility managers maintain their systems more effectively.

Where Is a Jockey Pump Installed?

A jockey pump is typically installed alongside the main fire pump within the fire pump room. It connects directly to the fire protection piping system and includes:

  • Pressure switches
  • Isolation valves
  • Check valves
  • Pressure gauges
  • Pump controller

Its location allows it to monitor and maintain pressure continuously without interfering with the operation of the primary fire pump.

Common Causes of Pressure Loss

Several factors can cause small pressure drops that require the jockey pump to operate.

These include:

  • Minor pipe leaks
  • Packing leakage around valves
  • Temperature changes affecting water volume
  • Small seepage through fittings
  • Routine inspection or testing
  • Aging sprinkler components

These pressure losses are normal and do not indicate a fire emergency.

How Is a Jockey Pump Sized?

A jockey pump is intentionally much smaller than the main fire pump.

According to NFPA 20, the jockey pump should have enough capacity to compensate for minor pressure losses but not enough capacity to satisfy the demand created by an open sprinkler.

Proper sizing ensures:

  • Quick pressure recovery
  • Stable system operation
  • Reliable fire pump activation during emergencies
  • Compliance with applicable fire protection standards

Improper sizing can either cause unnecessary cycling or delay fire pump operation.

Signs Your Jockey Pump Needs Attention

Like any mechanical equipment, jockey pumps require regular inspection and maintenance.

Watch for these warning signs:

Frequent Cycling

If the pump starts too often, the system may have a leak or incorrect pressure settings.

Pressure Fluctuations

Inconsistent pressure may indicate controller issues, worn components, or sensor problems.

Unusual Noise or Vibration

Grinding, rattling, or excessive vibration often points to bearing or motor wear.

Failure to Maintain Pressure

If the system pressure continues to drop after the jockey pump starts, repairs should be performed immediately.

Excessive Run Time

A properly functioning jockey pump typically runs for only a short period before shutting off.

Maintenance Best Practices

Routine maintenance helps ensure reliable performance and extends equipment life.

Recommended practices include:

  • Inspect pressure gauges regularly.
  • Verify pressure switch settings.
  • Test automatic start and stop functions.
  • Check for piping leaks.
  • Inspect valves and electrical connections.
  • Lubricate components according to manufacturer recommendations.
  • Schedule annual professional inspections.

Preventive maintenance minimizes unexpected failures and helps maintain code compliance.

Does Every Fire Protection System Need a Jockey Pump?

Not every system requires one, but most commercial, industrial, and high-rise fire protection systems include a jockey pump because of the significant operational benefits.

Large facilities such as:

  • Hospitals
  • Office buildings
  • Warehouses
  • Manufacturing plants
  • Educational institutions
  • Airports
  • Shopping centers

commonly rely on jockey pumps to maintain system readiness and reduce unnecessary fire pump operation.

Choosing the Right Jockey Pump

Selecting the correct jockey pump depends on several factors, including:

  • Building size
  • Fire protection system design
  • Required pressure levels
  • Local fire codes
  • NFPA compliance requirements
  • Pump controller compatibility

Working with an experienced fire protection pump supplier ensures proper sizing, installation, and long-term reliability.

Regular inspections, proper sizing, and professional maintenance are key to maximizing the performance and lifespan of both your jockey pump and the entire fire protection system. Investing in the right equipment today helps protect lives, property, and business continuity when it matters most.

Frequently Asked Questions

What is the purpose of a jockey pump in a fire protection system?

A jockey pump maintains water pressure within the fire protection system by compensating for minor pressure losses. This prevents unnecessary activation of the main fire pump.

Can a jockey pump replace a fire pump?

No. A jockey pump only maintains system pressure. It cannot deliver the high water flow required during a fire emergency.

How often should a jockey pump be inspected?

Routine visual inspections should be performed regularly, with comprehensive testing and maintenance conducted according to NFPA 20 recommendations and local fire codes.

Why does my jockey pump keep turning on?

Frequent cycling may indicate a small leak, pressure switch issue, or improper pressure settings. A professional inspection can identify the root cause.

Is a jockey pump required by code?

Many commercial fire protection systems use jockey pumps to maintain system pressure and improve reliability. Requirements depend on system design, applicable codes, and project specifications.

Heating and Cooling Pumps: 10 Installation and Maintenance Practices


Also known as the HVAC pump system, heating and cooling pumps are integral to maintaining comfortable indoor environments in any residential, commercial, or industrial setting. They play a critical role in circulating water or refrigerants to transfer heat or provide cooling. 

Pump solutions for HVAC are essential for cooling towers, boilers, hydronic mechanical systems, and more. However, several facilities managers, architects, and designers often overlook the proper installation and maintenance. 

Let’s delve into the world of heating and cooling pumps, exploring the best practices for maintenance and installation. 

Pump Maintenance in HVAC Systems

You can purchase an energy-efficient HVAC pump for your commercial application. If you don’t install and maintain it properly, it will result in additional costs in replacement parts, labor expenses, and equipment downtime. To keep heating and cooling pumps running for the long haul, you must ensure that best practices are followed. 

1. Select the Right Mechanical Seals

If mechanical seals go wrong, it’s probably due to improper installation. Most bearing failures result from misaligned pump shafts, excessive heat, and dirt or moisture contamination. 

First, pick the correct seal for your application. You should avoid operating it at a shut-off condition for more than a few minutes. Also, don’t run the pump dry. Lastly, ensure the HVAC pump shaft is aligned correctly during installation. 

2. Take Care of the Additional Load 

Avoid adding additional stress to your energy-efficient HVAC pump. Make sure it includes flexible connectors to prevent any external piping load. In addition, please ensure that adjacent piping hangers are correctly installed with the help of a professional. 

3. Install Only One Pressure Gauge

Some people assume that two gauges are better than one. However, installing multiple pressure gauges will badly affect pump performance. So, install only one pressure gauge according to the operation manual. 

4. Consider the Foundation of the Pump 

If you don’t want the pump impeller to wobble around like an old ceiling fan, ensure the pump is aligned correctly to maintain balance and decrease pump vibration. This is especially true for base-mounted end pumps. For other types of pumps, the impellers must be appropriately balanced before startup. 

5. Install External Seal Flush Lines

Installing an external flush will help you keep damaging solids away from the seal. It isolates the seal from pumped fluid and cools down the seal by carrying away the seal-generated heat. You can also add a sediment separator on the seal flush line to boost the life expectancy of the seals. 

6. Use Drain Pans

Be sure to use drain pans for chilled water condensation. Piping the drain pan to a floor drain helps keep the room safe from stray puddles. Also, you must bleed the air from the lines since air has no role.

7. Protect the Pump from Debris

Use a suction strainer to protect the HVAC pump system from external debris. It will help clean your pump system and keep trash from ruining the impellers and seals. Also, remember that the suction diffusers have fine mesh temporary screens. These screens need to be removed after the initial startup and system flush. 

8. Replace Old HVAC Ductwork 

Proper ductwork is crucial when it comes to avoiding indoor air quality issues. Some people keep the old ducts even after installing a new HVAC pump system. This decision may save you money, but it’s not always a great idea. Old ductwork can easily trap impurities, such as dust and debris. Also, a poorly sealed duct can affect the air quality and pump performance. So, consider replacing old ducts. 

9. Locate the Pump for Easy Maintenance

Larger pumps need to be located for ease of service, such as removing the motor. There has to be sufficient room around the pump to remove the motor so that the mechanical seals, impeller, and bushings are easy to access. You can use a pump motor hoist beam for larger inline pumps to move the heavy motor for servicing. 

10. Avoid Making DIY Repairs 

Making DIY repairs might help you save money, but HVAC systems are not one of those cases. DIY repairs can put your energy-efficient HVAC pump at risk. This is because such repairs involve electricity and require various specialized tools and replacement parts. Even a small mistake can lead to safety concerns, such as a fire. 

Follow these HVAC installation and maintenance practices for optimal system performance and energy efficiency. We hope you keep these points in mind when installing an HVAC pump. To learn more about pump maintenance in HVAC systems, talk to the pump experts at Callaghan Pump!

Booster Pump for Home

Residential buildings often experience water shortages and inconsistent water pressure. These issues are common in high-rise structures and remote areas with limited water supply. Luckily, you can install a booster pump for home. These pumps are essential for providing a reliable water supply to homes, offices, and residential buildings.

Domestic booster pumps come in various types with their advantages and disadvantages. If you need a water booster pump, this article will help you address your water pressure issues and provide more reliable water pressure to your home. Let’s begin!

What is a Water Booster Pump System?

A water booster pump refers to high-pressure water pumps that are responsible for the movement of water. Mains water supply, industrial water distribution, and surface cleaning systems use water booster pumps to achieve high water pressure.

Industrial booster pumps are characterized by high pressure rather than high flow capabilities. This makes multistage centrifugal and side channel pumps an ideal solution. Depending on the application, you can also choose from cold or hot water booster pump systems.

Inline Water Pressure Booster

Inline water booster pumps are compact and economical, meeting all of your water pressure-boosting needs. Their symmetrical design allows for easy installation, where you can mount the pump vertically or horizontally. This makes it an excellent pump solution for:
 
● City water pressure boosting

● Irrigation system boosting

● Pressurizing water in the cistern

● Re-pressurizing after filtration

Maintenance of Water Booster Pump for Home

Domestic booster pumps help ensure a constant water flow in homes, offices, buildings, and industrial facilities. They require proper maintenance, care, and repairs to ensure the pump system is in good condition and operates efficiently. Performing regular maintenance prevents water booster pumps from serious issues and costly repairs.
 
  • Inspect for any signs of leaks: Leaks and clogs are common and can occur in various water pump components. So, regular pump inspections are required to check for any leaks or signs of wear and tear, especially on the seals and gaskets. Addressing leaks early can prevent extensive repairs. 
  • Lubricate moving components: Properly lubricating pump bearings and other moving parts can help extend the pump's life. Insufficient lubrication can lead to overheating of the pump.
  • Check for proper flow: The goal of pump maintenance is to ensure that the pump can move water through the system at the appropriate rate. So, conduct regular flow and pressure tests to ensure the pump system works correctly.
  • Clean the water pump: A clean water booster pump will not only last longer, but it will also perform better. Over time, debris and build-up can accumulate in your water booster pump, lowering efficiency and causing damage to the pump. So, regularly clean the pump’s housing to prevent debris from getting inside the pump.
  • Monitor for unusual noise or vibration: Unusual noises, vibrations, and sounds can indicate an issue in the pump. If you hear unusual noises, it may be a problem. Thus, monitor these signs during regular maintenance.

So, this is everything you need to know about home booster pumps. If you are ready to start your inline water pressure booster journey, contact the experts at Callaghan Pump today.

HVAC Pumps: 4 Different Types of Pumps to Consider


HVAC Pump

Commercial pumps are widely used in many HVAC systems. They provide the pressure required to move water through piping. However, the word “pump” can have several meanings.

When selecting a booster pump for an HVAC system, there are several factors to consider, such as operating expenses, energy costs, system reliability, etc. Also, there are different types of HVAC pumps. So, let’s look at the most common types of pump systems used in HVAC.
 

  • Circulator Pumps

Circulator booster pumps are used in low-capacity HVAC systems. They are designed to circulate water through a closed system in a loop between the discharge and suction sides without ever getting exposed to atmospheric pressure. These pumps can also be used in a completely closed system, which requires an expansion tank attached to the pump’s suction line to prevent the piping from becoming overpressurized.

Circulator pumps are most commonly single-stage pumps, and the size is typically under 150 GPM. While small systems are designed to be close coupled to eliminate the need for a mechanical seal, high-flow versions are vertical in-line pumps with mechanical seals.
 

  • End Suction

End suction is mostly a single-stage pump with a casing with suction on one side and discharge at the top. It can be either close or flexible coupled. While close-coupled pumps have the impeller directly mounted to the motor shaft, flexible-coupled pumps have the impeller and the motor shaft separated by a coupling.

Usually, end suction pumps up to 4000 GPM of capacity and 150 feet of the head are used in HVAC systems. Close-coupled pumps are preferred as they have the advantage of taking up less floor space. Make sure the pump is installed on a solid base.
 

  • Split Case

Like end suction, split case pumps are flexible coupled commercial pumps. With the assembly mounted to a baseplate, the suction and discharge sides are arranged horizontally and are perpendicular to the shaft. They are available in single suction, which means the water enters the impeller from only one side. Some split cases are also double suction, which means the water enters the impeller from both sides.

You can choose double suction pumps over single suction, as they can reduce the risk of hydraulic imbalance. They are also available with multiple impellers for multistage applications and can be horizontal or vertical split cases. The horizontal split case is best for HVAC applications as it is more economical for high-flow applications. Split case HVAC pumps can be used for large capacities up to 6,500 GPM and a head up to 600 feet.
 

  • Vertical in-line

Vertical in-line pumps can be either single or double suction. They are close-coupled and are directly mounted on the pump casing. These pumps are typically mounted and supported by the piping system to ensure a small site footprint.

For larger applications, the pump assembly can have a base for floor mounting. You can use inertia bases to reduce vibration from the rotating parts within the pump. Vertical in-line pumps are best for a capacity of up to 25,000 GPM and a head of up to 300 feet.

Low Water Pressure Booster Pump: Things You Need to Know

 

low water pressure booster pump

In this blog post, let’s explore what a pressure pump installation is, how it works, and why it may benefit your household. So, let’s get started!
 
You may struggle to solve your low water pressure woes, but you can think of pressure pump installation. It will improve not only your water pressure but also your lifestyle. From taking a shower or washing dishes, having a low water pressure booster pump in place means you don’t have to worry about an annoying water trickle coming out. If you notice low water pressure symptoms, a water pressure booster pump can help.

What is a Low Water Pressure Booster Pump?

A water pressure booster pump is a device that boosts the water pressure in your home. It works by increasing the flow of water through the pipes, which boosts the water pressure. This is particularly useful for high-rise homes that experience low water pressure due to gravity, long-distance water supply, low city water pressure, or high demand during peak hours.
 

How Does a Low Water Pressure Booster Pump Work?

A water pressure booster pump is installed in the main water line entering the building. It is typically connected to a pressure tank to regulate the water flow and ensure that the pump operates only when needed. When water is turned on, the pump automatically starts increasing the pressure to the desired level.

There are two main water pressure booster pumps: centrifugal and positive displacement. While centrifugal pumps are the most common ones and work by spinning an impeller that forces water through the pipes, positive displacement pumps work by using a piston action to move water through the pipes.

Why Do You Need a Low Water Pressure Booster Pump?

You might need water pump installations in your home for different reasons. Below are a few of the most common reasons behind the pressure pump installation:

  • Low City Water Pressure

If you live in a location with low water pressure from the main city supply, having a booster pump can increase the pressure in your home and improve the performance of your plumbing fixtures.

  • High Demand

Multiple people using water simultaneously is another reason you need a pressure pump installation to maintain adequate pressure.

  • Distance from the Main Water Line

Is your home located far from the main water line? A booster pump can help you increase the pressure and flow of water.

  • Older Plumbing

Outdated or damaged fixtures are another reason why you need a booster pump. It can help compensate for leaks or plumbing issues causing low water pressure.

If you are experiencing low water pressure in your home, consider water pump installations. By increasing the water pressure and flow rate, you can achieve better performance from plumbing fixtures and protect appliances from damage.

Low Water Pressure: A Booster Pump Selection Guide

 

low water pressure

A home is a place of convenience and comfort. In this blog post, we will discuss the benefits of a water booster pump, but first, let’s understand a few basic things!

What do Residential Booster Water Pumps do?

Nothing can be worse than low water pressure, especially when washing dishes or showering. That’s where booster pumps come in. These pumps are designed to increase water pressure in your home and can be beneficial in many ways.

There are various applications for residential booster water pumps, ranging from large buildings to smaller residential houses. While the application may vary, the pump’s purpose remains the same – to boost the water pressure to all the plumbing fixtures in the building.

How do Booster Water Pumps Work?

A booster water pump uses an electric motor or diesel engine to drive an impeller, which moves the water through the system and increases its water pressure. Booster water pumps are designed to work with minimal maintenance and decrease the risk of clogging or corrosion.

When You Need a Water Booster Pump?

The most basic reason you need a booster pump is poor or low water pressure. Another reason could be no water flow or fluctuation in water pressure from shower heads, faucets, or taps.

The characteristics of the building partly determine the need for domestic water pump installation. A large building, like a restaurant or hotel, has multiple water booster pumps from the bottom floor to the middle, which allows adequate water pressure from the ground floor to the top floor.

For residential buildings, one common reason is whether the home is on the town or city water system. When a house is on the town or city water, the available water pressure can be affected by the number of homes on the same line. As more houses are built, the likelihood of your water pressure being affected increases.

Conclusion

Water needs to be distributed effectively throughout your property. If you are experiencing low to no water pressure, contact the professionals to help you. We hope you find this booster pump selection guide helpful. If you need assistance, you can talk to us directly.

Fire Pump Casing Relief Valves: Everything You Need To Know

fire pump casing relief valves

When choosing and installing fire pump casing relief valves, make sure you do your homework. To learn more about casing relief pumps, feel free to read on.

Fire sprinkler pumps are a great way to supply fire protection systems with pressurized water and
ensure the smooth operation of fire protection devices. The fire pump's performance has a direct impact on the performance of the entire fire protection system, so it is crucial to ensure the pump is functioning correctly.

Fire Pump Casing Relief Valves

Fire pump casing relief valves are required for both diesel and electric fire pump models for abnormal conditions like engine over-speeding or excess suction supply. Also, they are required on VFDs when the bypass operation exceeds a system design. These valves should not be used as pressure maintenance devices to limit water pressure.

The main role of the pump casing relief valve is to automatically prevent controlled pumps from overheating. This happens when they are being operated at shut-off or no discharge. However, the valve is not required for those pumps for which the water for engine cooling is taken from the pump discharge.

Why Do You Need a Main Relief Valve on Fire Pump Diesel Engines?

When it comes to diesel fire pumps, one of the most common misconceptions is that you are no longer required to have a main relief valve. It is also incorrectly referred to as a relief valve in some scenarios. To comply with the NFPA 202 (National Fire Protection Association), you will need to determine two different things.
  • The performance of the diesel fire pump being considered
  • The maximum static suction pressure feeding the pump
Once you determine these, you can figure out whether you will need a main relief valve for your diesel fire pump. Just multiply the fire pump’s churn pressure by 1.21 and add the result to the maximum suction pressure. If the answer exceeds the pressure rating of the discharge fittings, you will need a main relief valve.

Sizing and Location of Main Relief Valves

The main relief valve shall be sized hydraulically to discharge sufficient water to prevent the pump discharge pressure. It should be adjusted for elevation to prevent it from exceeding the pressure rating of the system components. In case the discharge pipe employs more than one elbow, you will need to use the next largest pipe size.

In terms of its setting, the casing relief valve should be set at the point just below the lowest expected suction pressure, plus the shutoff pressure of the unit. It must be piped to drain. The location of the main relief valve shall be somewhere between the pump and the discharge check valve.

Key types of relief pumps include listed spring-loaded and pilot-operated diaphragm-type valves. In addition to that, the relief valve should discharge into an open pipe or into a funnel secured to the outlet of the valve. Also, the water discharge from the relief valve should be readily visible.

Installation of Main Relief Valves 

Make sure you don’t install a shutoff valve in the relief valve supply or discharge piping. Relief valve discharge piping should not be combined with the discharge from other relief valves. Also, the discharge piping from multiple relief valves won’t have to be combined with fire pump test piping.

If you would like to learn more about fire pump diesel engines or casing relief valves, feel free to get in touch with us.

New York Water Booster Pump: Things You Need To Know

New York Water Booster Pump

When a water booster pump is appropriately installed with a high-efficiency motor and speed control, it will deliver optimal performance. Here’s what you need to know about New york water booster pumps.


If you look at tall or high-rise buildings, you will notice that water has to fight against gravity to reach the top floors. This may result in a loss of water pressure and flow, making it difficult to perform daily chores like washing, cleaning, and showering. This is why domestic water booster pumps have become a necessity.

New York Water Booster Pumps

NY water booster pumps are being used to increase water pressure in both domestic and commercial places that are taller than four stories. They are designed to allow water to reach top floors in high-rise facilities, where it would be unable to reach otherwise.

In addition to that, some buildings receive water from a roof tank. They use the force of gravity to generate water pressure, gaining more force when the water leaves the tank. In these setups, the floors closest to the tank often have low water pressure. Consequently, a small water booster pump can alleviate the problem.

Working Phenomenon of Booster Pumps in Brooklyn

Water booster pumps work similarly to a fan. They have an impeller inside to boost the available water flow and pressure in the same way a fan’s blades enhance air velocity. These pumps are designed to operate with an existing pump. The key components of booster pumps are:

  • Body: A body or casing is used to keep water from splashing outside the booster pump. It protects the internal components of the pump from damage if it is subjected to a strong load.
  • Impeller: The role of an impeller in a booster pump is to push water that enters via the inlet and exits through the output. It is spun by a motor and may differ in numbers depending on the pump application.
  • Impeller blades: Impellers have a number of fixed impeller blades. With the help of these blades, they turn the water axially and radially.
  • Volute Casing: The volute casing converts the water’s speed into pressure, increasing its water pressure.
  • Inlet and outlet valve: Inlet and outlet valves draw the water in and out of the pump.

Water Booster Pump Types

NY water booster pumps are available as ordinary pumps or variable speed drive (VSD) pumps. While ordinary booster pumps work at a constant rate and don’t have the provision to increase the flow rate, VSD pumps can adjust the speed based on the different pressure head requirements. These pumps are great for minimising energy costs.

Other categories include multi-stage and single-stage booster pumps. Single-stage booster pumps are best for moderate pressure requirements in independent houses and residential buildings. On the other hand, multi-stage booster pumps are useful when the requirement of water pressure is extremely high. This includes pumping water uphill, catering to multiple buildings, maintaining the city water pressure, and carrying water over an extremely long pipeline.

End-Suction Pump: Know if It's the Right Booster Pump For You

End-Suction Pump

Using an end-suction pump for water-boosting applications is a common approach followed by many people. Here’s why it might be a great option for you.
If you are looking at this article, we can assume that you are seeking information on whether you should install a domestic water booster system. This article covers the end-suction pump, which is one of the most common water booster pumps out there. Read on to learn more about the end-suction water booster pump system.

What is an End-Suction Pump?

End-suction pumps are a type of centrifugal pump in which the suction is axial, and the discharge is perpendicular to the suction. They are often long coupled or close coupled. These pumps are designed as a back pull-out pump with a spacer coupling. This facilitates the maintenance and testing parts without disturbing the alignment with the motor. Hence, they are able to save on space and eliminate the need for motor alignment.

Typically, on a larger end-suction pump, the main feature of the casing is a dual volute to reduce the forces that are acting on the impeller, motor, shaft, or bearing. It is one of the most common types of water booster pumps, and its construction is relatively simple. Plus, end suction pumps are usually a single-stage pump and often come in multi-stage versions.

Impellers are available as enclosed radial flow, semi-open, vortex, helical screw, and disc rotor designs. The most commonly used materials are cast iron, bronze, and stainless steel. Some typical applications of end-suction pumps are:
  • Sprinkler systems and hydrant systems
  • Monitor systems and water curtains
  • Supermarkets and office buildings
  • High-rise complexes
  • Hospitals and hotels
  • Schools and colleges

What’s the Difference Between the Inline and End-Suction Pump?

Inline pumps are a derivative of the end-suction pump. Here, the suction and discharge are on the same axis to simplify the installation into the piping system without requiring any expensive foundations. Also, inline pumps are smaller in size than end-suction pumps and require less space. Due to their construction, inline pumps are easy to fit as valves to increase the water pressure at different points in the large processing pipes.

What is a Base Mounted End-Suction Pump?

When your water booster pump is long coupled and uses a coupling to join the pump and motor together, you will need a common base plate or frame. It supports the drives or machines and is important for large and heavy machines to reduce vibrations and piping noises. Below are some important end-suction pump piping details:

  • The piping must be generously sized to permit easy flow into the suction.
  • It has to be arranged in such a way that it eliminates air pockets.
  • Have at least 10 pipe diameters of straight pipe in the pump suction to normalize the flow, minimize the turbulence, and optimize the pump reliability.

Final Words

Offering the added bonus of saving space for your water pressure boosting application, the end-suction pump is the most common centrifugal pump arrangement with its horizontal shaft, overhung impeller, and bearing arrangement. It is one of the simplest types of centrifugal pumps and comes with motor slide rails and back pull-out designs that allow for ready access and ease of maintenance. Plus, it’s a precision-made domestic water booster system appropriate for both electric and diesel drives.
