Pump Rotation Terminology

Pump Rotation Terminology

Make sure that you verify your orientation when looking at the pump. For a horizontal split-case fire pump the rotation is defined by looking at the drive side of the pump unit. This means that if you were sitting on the motor and looking at the pump, a right-hand (clockwise) rotation has suction on the right and a left-hand (counter-clockwise) has the suction on the left.  Also don't forget there are no UL/FM listed "left hand rotation" diesel engines available on the market.




Conduit Box Location - Electric Motors

Some motors can have the conduit box in alternate locations, some cannot. It is dependent on the manufacturer’s design of the specific motor. The standard box location is the F1 location (box on right when sitting on the motor looking at the pump).
