HOW DO I DETERMINE THE ROTATION OF A PUMP?

ROTATION CHECK

​

Ensuring the rotation of the water truck centrifugal pump corresponds to the rotation of the drive shaft, either from a motor or a power-take-off (PTO) is critical for an effective pump operation.

​

The rotation setting of a centrifugal pump, motor, transmission or PTO is determined by viewing the device from the shaft side. There are are two types of rotation settings:

​

1. Clockwise - the rotation is clockwise if when viewing the device from the shaft side, the shaft is rotating or spinning in the the same direction as the rotating hands of a clock.

2. Counter-Clockwise - the rotation is counter-clockwise if when viewing the device from the shaft side, the shaft is rotating or spinning in the opposite direction as the rotating hands of a clock.

​

In summary:

 

• If your drive shaft rotation is Clockwise - your pump needs to rotate Counter-Clockwise

• If your drive shaft rotation is Counter-Clockwise - your pump needs to rotate Clockwise.

Note: Centrifugal pumps will still pump liquid when the rotation is incorrect, however Gallons Per Minute and head will be a fraction of the published performance.
