5.2.1 Motor Rotation
Motor can be operated in either direction, clockwise or counterclockwise. Verification of motor
direction is not necessary at startup.

PULSAR pumps may be shipped with the drive motor packed separately. This is done to avoid damage
during transport.

1. Remove the unattached coupling half from the motor adaptor. Ensure that the elastomer
coupling spider remains in place, on the coupling half that remains attached to the worm shaft.
2. If applicable, remove any tape or retainer rings that hold the motor shaft key in place.
3. Place the loose coupling half on the motor shaft. Align the keyway with the key and align shaft
end to inner coupling surface as shown in figure above.
4. Tighten the setscrew onto the shaft key.
5. Place the motor in a vertical position and align the coupling teeth.
6. Install the motor downwards onto the adaptor. The plastic guide will assist in aligning the
coupling halves. Final position can be achieved by slightly rotating the motor until the coupling
jaws align.
7. Rotate the motor until the clearance holes in the adaptor and the tapped holes in the motor align.
Fasten the motor to the adaptor using the supplied bolts (4). Tighten bolts evenly to secure
motor.
5.2.3 Electrical
Wire the PULSAR drive motor according to the motor vendor’s nameplates and instructions, and
according to any appropriate national and local electrical codes and regulations.
If the motor is to be utilized with a Pulsafeeder controller, such as the DLC, DLCM, or MPC,
consult the appropriate Pulsafeeder IOM for further motor wiring instructions.
