Fire Pump Pressure Shortage Do

Dec 01, 2016

Cause analysis and solution to the fire pump pressure is low:

1, pump no water or no suitable exhaust

Solution: check that the pump and inlet piping is filled full with liquid.

2, the speed is too low

Solution: check for proper electrical wiring, voltage is normal or Turbo steam pressure is normal.

3, the system head too high

Solution: check the system head (especially the friction losses).

4, suction lift too high

Solution: check the existing net pressure head (inlet piping is too small or too long will cause a lot of friction losses).

5, impeller or pipeline plug

Solution: check for obstructions.

6, the direction of rotation is wrong

Solution: check the direction of rotation.
