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

There is no “one size fits all” answer when it comes to fire pumps. Fire pump flow tests are usually done through a special pump test header.

When should fire apparatus be replaced?

25 years
First, departments should execute caution when considering whether to refurbish or update their current apparatus. While it may seem like a good, quick fix, these smaller fixes add up quickly. Any trucks over 20 years old will see no value from upgrading, and after 25 years a fire apparatus should be retired.

How do you calculate the GPM of a fire pump?

For example, if you have a 40,000-square-foot building that is all ordinary group 1, the calculation would be 1,500 x 0.15 (density) = 225 + 250 (hose demand) = 475 gpm total for the fire pump. If the structure has multiple hazards, the hazard with the highest gpm calculation dictates the pump size.

How do I know what size fire pump I need?

What is the size of pump room?

The size of the fire pump house should be 5.5 m x 8 m x 3.5 m, where engine driven fire pump, electric motor driven fire pump and pressurization pump are installed.

What are the NFPA requirements for fire pump testing?

The NFPA requires this test for pumps rated for over 750 gpm. Immediately after the 20-minute test, run the pump for 5 minutes, at its rated capacity, at 165 psi. Run the pump for 10 minutes at 70% capacity and 200 psi. Run the pump for 10 more minutes at 50% capacity and 250 psi.

What’s the maximum time a fire pump can pump water?

This determines how long it takes to lift water to the pump so that pumping can begin. For pumps rated up to 1,250 gpm, a 30-second maximum time is allowed, and a 45-second max is permitted for pumps rated for 1,500 gpm or higher.

How long does it take to test a fire pump?

Run the pump for 10 minutes at 70% capacity and 200 psi. Run the pump for 10 more minutes at 50% capacity and 250 psi. Once the test is complete, make sure the test is properly documented. This enables you to proactively schedule repairs so that your apparatus will meet all required standards.

What should the pressure be on a fire pump?

Run the pump for 20 minutes at 100% of rated capacity, with a net pump pressure of 150 pounds per square inch (psi). The NFPA requires this test for pumps rated for over 750 gpm.
