Electric Fire Pump (Centrifugal)

The electric fire pump is the primary pressurized water source for hydrant systems. It is typically a horizontal split-case or end-suction centrifugal pump driven by a 3-phase induction motor and controlled by an auto-start panel.

Pumps are sized to meet the hydraulic demand of the building (commonly 100–1000 LPM at 8–10 bar) and comply with IS 12469/IS 15301 guidelines. The pump starts automatically when system pressure drops below the set point.

Weekly churn tests and periodic flow tests verify performance; discharge gauges and relief valves protect the pump from dead-heading.
