Fire Suppression system in NYC: Operating Principles of Fire Pumps

 

There are different fire protection pumps that can be used in a variety of situations. Continue reading to learn more about different types of fire pump systems.

When planning your fire suppression system in NYC, you will need to consider fire pumps that are designed to boost water pressure for the system. They are an essential part of a fire sprinkler system and helps it meet water pressure needs during the event of a fire. Read on to learn everything you need to know about fire protection pumps.

Fire Pumps in NYC

Fire protection pumps are centrifugal pumps used for pumping fire-fighting water. They are designed for both transportable and stationary applications – making them suitable for a variety of applications in taller buildings, smaller piping, restaurants, hotels, etc.

When choosing a fire pump for your application, please note that an incorrect pump can result in inadequate pressure or flow. As a result, this may cause several problems, such as:

• Fire protection systems not functioning properly
• Too much pressure, which can cause components to burst
• Irregular spray patterns from sprinklers

Operating Principles of Fire Protection Pumps

To size and select the correct pump, it is important to have an understanding of the different operating principles, types, and applications of fire pumps. There are two main principles of fire pump operations:

Centrifugal Pump

Centrifugal is the principle of a spinning action, which helps the pump to generate centrifugal forces. Water starts off in the center of an impeller and is thrown to the outer parts of the impeller. This action is quite similar to a spinning ride at a carnival. The faster the spinning action, the more force is applied to the outward direction.

Positive Displacement

Positive displacement is the principle of capturing a certain amount of water in a single revolution. This is done by using a mechanical process to displace the water. To give you an idea, just think of an air compressor with pistons to compress the air. As the outside motor spins, pistons are forced up, and they build up pressure.

Each of these two operating principles has its pros and cons. For instance, centrifugal pumps are better at higher flow rates. Positive displacement provides constant flow at a range of pressures, but typically has low flow rates. Positive displacement is great for pump fluids that are not necessarily water. Some popular applications of centrifugal pumps are low- and high-rise buildings.

Types of Fire Protection Pumps to Consider

Jockey Pump

This is a small pump connected to a fire protection system and maintains pressure in the sprinklers. It helps you ensure that if there is a pressure drop, a jockey pump would be activated to overcome it.

Hydrant Pump

Fire hydrant pumps are high-pressure pumps that are designed to boost the firefighting capacity of your building by increasing the water pressure in the hydrant service.

Sprinkler Pump

Sprinkler system pumps consist of both fire-fighting main pumps and jockey pumps that jointly ensure sufficient water pressure to the sprinkler system in case of a fire.

Diesel Standby Pump

As an alternate source in the absence of an electrical power supply, diesel standby pumps have been used to supply an adequate amount of water pressure to fire protection systems.

Multi-Stage Multi Outlet Pump

Multi Stage Multi Outlet Pumps (MSMO) offer several benefits. It only needs a fewer number of pumps, is energy saving, and is significantly space-saving. These pumps are available to satisfy large specifications for automatic fire protection in high-rise and multiple-story buildings.
