Basic Fire Water Pump (FWP) system
Fire water system are pressurize and ready to be use at any time. To ensure system always pressurize and could meet usage water demand, it need pump to play that important roles. This time let us discuss on fire water pump arrangement.
Normally fire water pump consist of 3 type or function/duty. the pump are:
i) Jockey pump ; to make up small pressure loss in the fire water main ring.
ii) Duty pump ; to give more pressure when there is significant pressure lost in the fire water main ring.
iii) Standby pump: Diesel driven pump to support duty pump when there is very high pressure lost due to high water demand from fire water main ring.
Both Jockey and Duty pump are electrical driven pump. Standby pump are design to be independent source of power so that when there is electrical failure, it still can perform the duty to supply water to the fire water main ring.
Diesel fire water pump startup could be set using:
1. Battery
2. Compress air
There is 2 type of testing that normally done to ensure FWP system in good condition which is:
1. Functional test : testing that ensure pump running sequence are as per design. This test done weekly by some organization.
2. Capacity test : testing to check pump could delivered water volume as per intended design and factory test. This test normally done annually. Normally insurance company would like to check this report.
