Fire Pump
Fire pumps are usually housed in a pump room very close to the fire tanks. The key thing is that the pumps should be located at a level just below the bottom of the fire tank, so that all the water in the tanks can flow into the pumps by gravity.
Like all important systems, there must be backup pumps in case the main pump fails. There is a main pump that is electric, a backup pump that is electric, and a second backup pump that is diesel-powered, in case the electricity fails, which is common. Each of these pumps is capable of pumping the required amount of water individually - they are identical in capacity.
Capacity of the pumps
- the area covered by hydrants / standpipes and sprinklers
- the number of hydrants and sprinklers
- the assumed area of operation of the sprinklers
- the type and layout of the building
