Explaining the Operation and Testing of New York Fire Pumps

August 10th, 2022

New York Fire Pumps, also known as booster pumps, are great when it comes to boosting the available water pressure in fire sprinkler systems. These pumps are connected to a water main, tank, or reservoir that is designed for firefighting purposes. In some cases, a secondary water source is also required. This is true for bigger applications or buildings that often have high water demand. So, consider installing a fire pump if your water supply does not provide adequate pressure for the operation of sprinklers.

How Does a New York Fire Pump Operate?

A fire pump usually consists of a suction port, which draws water from the main source. A discharge port is available to expel water at a higher pressure rate. Also, a check valve prevents water from getting back into the source when the fire pump is not working or operating.

Additionally, a smaller pump, known as a jockey pump, is sometimes used to supplement small pressure changes that result from leaks or expansion within the water system. This jockey pump has a field adjustable pressure-sensing device that detects pressure drops in the sprinkler system.

How to Test Your Fire Pump?

If your property is equipped with New York Fire Pumps, you will need to perform periodic inspection, maintenance, and testing. Plus, you should include alarm devices to ensure reliability during an emergency. In case the fire department monitors your sprinkler system, notify them before and after you conduct any test.
Here are a few important factors to consider when you are testing your New York Fire Pump.

1. Pump Churn

   Check whether the pump starts with a drop in water pressure. Make sure you record the gauges on the discharge and suction sides.

    

2. Pump Alarm

   Test the pump alarm for any potential pump running, power failure, and valve tamper. Check whether the alarm functions with the central station.

    

3. Pump Flow

   Operate the fire pump with water flowing through the system. Test the pump churn, which is at 100% and 150% of the rated GPM capacity. The resulting pressure must be equal to the pump-rated pressure.

    

4. Transfer Switch Operation

   Check the manual or automatic transfer of power supplies. This should be done annually.
