What is the rated capacity for pumps under this standard?

The nominal discharge capacity must be between 1100 and 1600 litres per minute at a specified head (as per title and Clause 3.1).

What is the standard delivery pressure the pump must achieve?

The pump must deliver its rated output at a head of 70 m, which is equivalent to 0.7 MPa or approximately 7 kgf/cm² (Clause 3.1).

What is the maximum time allowed for priming the pump?

The pump should be able to prime water from a 7-meter suction lift within a maximum of 30 seconds (Clause 3.1).

What materials are specified for the pump casing and impeller?

The pump casing should be of light alloy or gunmetal/bronze, and the impeller should be of gunmetal/bronze (Clause 5).

Practical Notes

The pump's performance is highly dependent on the engine's condition; regular engine maintenance as per the manufacturer's guidelines is critical for reliability.

Always use suction strainers to prevent debris from entering and damaging the pump impeller, especially when drafting from open water sources.

Verify that the hose couplings (e.g., instantaneous type as per IS 903) on the pump are compatible with the fire service's existing hose inventory.
