Pump without motor (CR, CRI, CRN 1s, 1, 3, 5, 10, 15, and 20
only)
If you purchased a pump end without motor, the shaft seal has
been set from factory. Do not loosen the three set screws on the
shaft seal when attaching the motor.
Pump without motor (CR, CRN 32, 45 and 64 only)
If you purchased a pump end without motor, you must install the
shaft seal. The shaft seal is protected in its own box inside the
pump packing crate. To protect the shaft and bearings during
shipment, a transport protector is used. Remove the transport
protector prior to installation of the shaft seal. Read the seal
installation instructions which are included in the pump packing.
4.7 Drive-end motor bearing
Make sure to use the correct type of drive-end (DE) motor
bearing for the bare-shaft pump. Please check the specific pump
range and pump version stated on the nameplate and select the
corresponding DE bearing.
