The diesel engine shall conform to the requirements of the National Fire Protection Association, Pamphlet #20 and shall be specifically approved for fire pump service. It shall operate at a rated speed not exceeding the above RPM and shall develop sufficient horsepower to drive the pump with reserve power.
- Cooling Water System
The cooling water supply for the heat exchanger shall be from the discharge of the pump, taken off prior to the pump discharge valve. The pipe connection shall include four (4) manual shut-off valves (including by-pass line), two strainers, two pressure regulators, a listed automatic solenoid valve and a pressure gauge, piping and fittings all fitted to engine, per NFPA20, by the pump manufacturer.
- Storage Batteries
One set of dual heavy duty lead acid batteries shall be provided and furnished in a dry charge condition with electrolyte liquid in separate containers. Suitable battery rack and 60" of battery cables shall be included.
- Fuel System
The fuel system shall be Underwriters' type and shall consist of an above ground storage tank of _________gallons as recommended per NFPA20, fill pipe and cap, manual shut-off cock, flame arrestor, oil level gauge and braided bronze flexible connectors. The tank shall be supplied with legs for floor mounting. Approved seamless copper tubing and miscellaneous pipe and fittings shall be supplied by the mechanical contractor.
- MINIMUM FITTINGS

- One (1) air release valve.
- OTHER ACCESSORIES
Pump shall be fitted with one (1) eccentric suction reducer and one (1) concentric discharge increaser (by mechanical contractor) to fit NFPA20 recommended piping sizes. One (1) outside test header shall be supplied with one (1) set of 2 1/2" hose valves with caps and chains to suit the rated pump flow. One (1) main relief valve and one(1) waste cone shall be supplied.
- AUTOMATIC DIESEL ENGINE CONTROLLER
The Fire Pump Controller shall be manufactured by ____________ Model ____________ built strictly in accordance with the latest requirements of the NFPA. Controller shall be listed and labeled by Underwriters Laboratories of Canada (ULC) by Underwriters Laboratories (UL) and/or approved by Factory Mutual (FM).
- JOCKEY PUMP
The jockey pump shall be Model No. ______________ fo a capacity of ___________ USGPM and a pressure boost of ____________ PSIG. The jockey pump shall be driven by an open drip proof electric motor of_______HP ________ RPM ________ VOLT ______ PHASE________ CYCLE.
- JOCKEY PUMP CONTROLLER
The jockey pump shall be controlled by an automatic jockey pump controller model ____________ with full voltage starter.
- MOUNTING AND TESTING
Fire pump will be hydrostatically tested to a pressure recommended by UL, ULC or FM. The fire pump shall be subjected to a performance test at rated speed. The pump shall furnish not less than 150% of rated capacity at a pressure not less than 65% of rated head. The shut-off head shall not exceed 140% of rated head. A certified test.
