Important Notice about vertical turbine applications:

NFPA-20 states the following:

7.5.1.6.1 For drive systems that include a right angle gear drive, the pump manufacturer shall provide a complete mass elastic system torsional analysis to ensure there are no damaging stresses or critical speeds within 25 percent above and below the operating speed of the pump and drive.

7.5.1.6.2 The torsional analysis specified in 7.5.1.6.1 shall include the mass elastic characteristics for a wetted pump with the specific impeller trim, coupling, right-angle gear, flexible connecting shaft, and engine, plus the excitation characteristics of the engine.

Notice

A service factor must be applied to the calculated end-use application torque. The calculated end-use application torques, as adjusted by the service factor, shall not exceed the torque rating of the connecting shaft at the applicable speed.

Service Factor (SF) = 1.5
(6 Cylinders or More -diesel engine)

Service Factor (SF) = 2.0
(5 Cylinders or Less-diesel engine)

Selection of Flexible connecting driveshaft shall be based on rating of the driver and not the pump.

Although UL listed torque ratings are shown at specific speeds, CFP drive-shafts can be applied at any intermediate speed. To determine the intermediate certified power, make a linear interpolation from the CFP UL Listed power curve. Contact Cummins Fire Power if you have questions.
