Lubrication
W A R N I N G
A pump unit operating without proper lubrication will damage the bearings and cause a pump seizure.
Use grease lubrication always when the pump is mounted in an inclined position.
Check the oil or grease used for the lubrication of both the pump and motor bearings before start-up. Condensation
or ingress of dirt and water may occur if the pump unit is stored for a long time before installation and start-up.

It is imperative to detach the coupling spacer before checking the rotation direction of the motor.
The motor rotation must be counter-clockwise when viewed from the coupling end (D-end, Fig. 1) of the motor. (The
pump rotation is clockwise when viewed from the coupling end.)
The direction of rotation must correspond to the arrow sign (972.31) on the bearing housing (330.31).
