What is a fire pump flow test?

What is a fire pump flow test?

The annual fire pump flow test is a full test of a pump’s capabilities and is arguably the most critical test. It is conducted once a year to measure flow and pressure and make sure the fire pump is ready to respond to a call to service. A maximum of 140 percent of rated pressure at churn (no flow)

What are the three test points that a new fire pump must meet?

3 of this standard, the annual flow testing of fire pumps should be performed as a minimum at three points across pump curve; no flow (churn), 100% of the pump rated capacity and 150% of the pump rated capacity by controlling discharged water through approved discharge devices.

What is a fire pump acceptance test?

The field acceptance test is intended to verify that the pump is operating in accordance with the specified pump output. During the flow test, pump output pressure and flows are measured and then plotted on hydraulic graph paper. Field acceptance test results are compared to certified shop test curves.

What is the NFPA Standard for pump testing?

The current NFPA 1901, Standard for Automotive Fire Apparatus–1996, 5-3.2, requires a tank with 500 gallons or more of water to pump flow at a minimum rate of 500 gpm. This flow rate must be sustained for a minimum of 80 percent of the tank`s capacity. Alternative pump testing from a hydrant is allowed.

What is a test header?

A test header allows for the flowing of large quantities of water through multiple hoses. The fire department connection (FDC) allows the fire department to supplement the fire protection system in the event of a fire (refer to the August 2006 Quick Response newsletter).

Is a fire pump test header required?

Where a fire pump test header is installed, NFPA 20 requires that it be installed on an exterior wall or in another location outside the pump room that allows for water discharge during testing.

How do you test a fire pump?

Electric Fire Pump Testing Procedure

1. Call the alarm company and have the system put on test.
2. Close the main control valve to the system.
3. Perform manual start of the fire pump by pressing the start button on the fire pump controller.
4. Verify there is sufficient flow from the 3/4” casing relief valve on the fire pump.

How do you do a fire pump test?

The monthly churn test requires electric powered pumps to be tested as follows:

1. Run pump for a minimum of 10 minutes.
2. Record the system suction & discharge pressure gauge readings.
3. Check the pump packing glands for slight discharge.
4. Adjust glands nuts; if necessary.
5. Check for unusual noise or vibration.

What is header in fire fighting?

A header network of pipes, often in the form of a ring main that transfers the water from the pumps to the fire.

What is a fire pump engine?

A fire pump is any type of purpose-driven pump used within a fire protection system. It can be driven by diesel engines, electric motors or even steam and is used to provide increases in water pressure to meet the design requirements of a fire protection system. Fire pumps do not create a water supply.
