Diesel Driven fire pumps 1

[Chuk1t]

I have an application that requires a diesel driven pump rather than an electric pump with a standby generator.

My question is how to handle ventilation requirements. The unit will be located in a basement below grade with access to louvers in wall at grade. The engine is approximately 50 Hp and maximum room temp allowed is 120 deg F.

Since it's assumed that electric power is off while diesel is running mechanical ventilation is not available.

Is it typical practice to depend upon the engine fan to pull all the required cfm thru the room??

what other issues need to be addressed?

Like any other diesel engine its radiator exhaust air must be ducted outside the building and intake louvers provided for fresh combustion air intake.

The radiator fan is capable of pulling the required air, no additional mechanical ventilation is required. The intake louver has to be correct type. Gravity closed and open upon negative pressure in the room.

Radiator air duct is usally very short.

The flue exhaust is separate.

The original post omits the word "fire" in front of "pump" so I may be reading too much into this, but typical diesel driven fire pumps run a certain amount of the pump discharge through the engine cooling circuit and back into the discharge line or down the drain, so there would be no radiator discharge to worry about in that case.

Suggestion: Check with the manufacturer of the Diesel Fire Pump whether the set is designed for indoor or outdoor operation.
