Short Description:
* Fire pumps are designed for whole operational life, the maximum reliability is always the first priority
* The components affixed onto a steel framing structure
* Each controller has its own individual pressure sensing line
* The suction line should never include a strainer
* Check valve and butterfly valve in the discharge line
* NFPA 20 not allows suction from negative level for end suction and split case pumps
Principle:
When pressure drops below the set value, jockey starts running with the signal from the pressure switch and continues running for 10 minutes till the system pressure reaches the set value. If the pressure continues drop, first the main pump starts to run. If the system pressure can not supply and pressure continues drop, the standby pump starts to run.
