When it comes to understanding your building’s water pressure, there are several different components you need to consider. One of these components is the variable-speed water pump, an essential element in any building that requires increased water pressure to meet its daily water demand.
Here’s everything you need to know about variable speed pump installation, service, and maintenance. Continue reading.
What does a Variable Speed Water Pump do?
Water booster pumps add pressure to a building’s water supply when the water mains pressure is insufficient. They are a common type of pump used in most multi-story apartment complexes, high-rise structures, hotels, restaurants, etc. These buildings require pressure booster pumps to supply adequate water pressure to different terminal units, such as showers and bathrooms.
When water consumption or demand changes, additional pumps can be staged on or off to maintain the required water pressure. This makes variable booster pumps a great addition to water booster pumps as an alternative to pressure control valves.
The role of a variable-speed water pump is to maintain the required pressure when the flow rate decreases, or suction pressure varies. It helps the booster pump avoid over-pressurization and control problems.Benefits of Variable Booster Pumps
A variable speed pump provides several key advantages that simplify a booster pumping system, enabling additional control and greater efficiency. The top benefits include:
- Programmable inputs: Variable booster pumps come with digital and analog inputs that can aid in precise speed control.
- Bypass or hand/off-auto function: This is a built-in function to help the pump run at constant speed if the variable speed drive malfunctions.
- Networking capability: This specific feature allows for real-time monitoring and control from other control systems.
- Reduced energy usage: By reducing speed to suit the water demand, you can stop a pump during periods of low flow rate and save energy.
Servicing Your Variable Speed Water Pump
A variable speed pump eliminates the pump cost and maintenance, saving up to 20% or more. Make sure you service it to maintain its performance and reliability. Here's an overview of how often a variable-speed booster pump should be serviced:
- Routine Inspection
The booster pump and variable speed pump should be visually inspected monthly. During the inspection, you need to check for any signs of leaks, clogs, unusual noises, or visual damage to the pump, motor, and associated components.
- Operational Testing
This testing is done every three months. It requires conducting operational tests to ensure the water booster pump functions properly. Ensure you run the pump through its normal operating cycle and verify that it can maintain the desired water pressure. Also, check for any fluctuations or irregularities in pressure.
- Annual Maintenance
A qualified technician should perform a comprehensive annual service. It typically includes inspecting and lubricating pump bearings, seals, and other moving parts. Cleaning of strainers or filters must be carried out to ensure unobstructed water flow. Don’t forget to inspect the electrical connections, sensors, and controls.
- Professional Service
Every 3 to 5 years, depending on the manufacturer's recommendations and usage patterns, you need to ensure a thorough professional inspection and servicing of the pump. It will involve disassembling the pump, inspecting internal components, and replacing worn or damaged parts.
- Emergency Service
If you notice any performance issues or unusual vibrations, it's essential to have the booster pump serviced promptly to prevent any further damage. You need to ensure consistent water pressure, so consult the manufacturer's documentation and guidelines for your particular pump model. Ensure you work with qualified technicians or service providers specializing in emergency pump maintenance.
Servicing helps ensure the longevity of the variable booster pump, reducing the risk of unexpected breakdowns. It ensures that the water pressure remains consistent, which is essential for adequately functioning any water-dependent equipment in a building.
