Product Usage Instructions
Installing ADC-44 Wash Pump Motor
When installing a new motor for the 3-HP pump:
- Always use a new secure bolt with a locking strip to hold the impeller to the motor shaft.
- The bolt should only be used once and never reused.
Make sure the impeller turns counter-clockwise when looking at the wet-end of the pump.
Pump Seal Installation
Lubricate the pump housing with dish soap. Then follow these steps:
- Place the housing on the motor with the sleeve installed.
- Press the ceramic half of the seal with boot into the housing.
- Use a 1.5 OD plastic tube to press the seal firmly into place.
- Press graphite till it seats on ceramic. Key in the keyway, place impeller & tighten lock bolt to 15 ft/lbs.
Electrical Connection
Connecting 3-phase power to the motor is done at terminals L1 Red, L2
White, L3 Blue. Follow these steps:
- If motor rotation is incorrect, switch any two of the phase wires.
- Check the arrow on the motor for correct rotation indication.
FAQ
-
Q: What should I do if the key way in the motor shaft or impeller is damaged?
A: If the key way is damaged, the motor or impeller are not serviceable and should be replaced. -
Q: How should I reverse the rotation of the motor if it is incorrect?
A: To reverse the rotation, switch any two of the phase wires connected to terminals L1, L2, L3. -
Q: What is the power requirement for the motor?
A: The motor operates on low voltage (208-230V) or high voltage (460V) power supply.
TECHNICAL SUPPORT MATERIAL
Installing ADC-44 Wash Pump Motor
When installing a new motor for the 3-HP pump, always use a new secure bolt w/locking strip (098-1613) to hold the impeller (282-6303) to the motor shaft.
The stainless motor
shaft sleeve (284-6203) with two internal o-rings (289-6618) should already be
installed on the 7/8” motor shaft. The sleeve is 1.5” diameter OD, this is the
surface that the pump seal (292-2001) rides on.
When looking at the wet-end of the pump, the impeller should turn counter-
clock wise. Check rotation.
Installing the pump seal is typical of the standard 5/8”motor seal
installation, only larger parts. 
CAUTION
When installing the impeller, carefully inspect the key way in the motor shaft
and the impeller. If the edges of the key way are flattened out or pushed over
(see photo below) the motor or impeller are not serviceable and should be
replaced.
Electrical
Connecting 3-phase power to the motor is done at terminals L1 Red, L2 white,
L3 blue. Note: with 3-phase motors, there is a 50/50 chance of the motor
rotation being correct when first connected to power—to reverse, switch any
two of the phase wires.
Look at the arrow on the motor for correct rotation.
