Don’t Ignore Regular Inspection of High Pressure Fire Pump

Fire pump is an important tool to guarantee our security in case of an emergency; it helps to supply hydrants and sprinkler systems with the flow and pressure needed to control a fire. Inspection, testing and maintenance of fire pumps are critical to fire safety. This device can be divided in to various sorts according to its usage and composition. High pressure fire pump is one type of it.

The regularly inspection of the fire pumps is a visual examination, its purpose is to ensure the equipment is in an operating condition free of physical damage and is capable of providing continuous delivery for required fire protection demands. Another purpose is to detect deficiencies that may not be obvious by visual inspection.

When checking a high pressure fire pump, you should pay attention to the following aspects:

*Check the power indicating light on the controller to verify that there is power to the pump

*Check to make sure there is adequate heat in the fire pump room (not less than 40ºF and 70ºF for diesel pumps without engine heaters) during colder months

*Check to make sure ventilating louvers are free to operate

*Check to make ensure the pump suction, discharge and bypass valves are open

*Examine piping, fitting, and connections for any physical damage or leakage

*Check to make sure the suction and discharge gauge pressure reading is normal

*Check the system pressure gauge to ensure the system pressure reading is normal

Fire pump should be thought of as a group of components that work together to create a complete machine assembly. The main components include water supply and discharge piping, the fire pump, a driver to provide power to the fire pump and a controller, which turns the fire pumps on and off and monitors its operation.

Fire pump provide waterflow for sprinkler systems, standpipes, hydrants and other fire protection systems. If the existing city water supply is not adequate to provide enough waterflow at pressures needed by the sprinkler systems, a fire pump may be used to boost the pressure. Fire pumps are also installed in conjunction with a tank where no public water supply exists. In this case, the pump and tank may be the sole water supply for the sprinklers and hydrants of your facility. Facilities with critical operations, or high values, may have a fire pump and tank, which is redundant to the existing public water supply.
