pump says CW rotation, does that mean it wont work if my system runs the shaft counterclockwise?
Answer by: Customer Support on Apr 15, 2025, 6:18 AM
Correct, rotation matters on vane pumps. This unit is built for clockwise rotation only, so running it backwards will cause it to cavitate and fail pretty quick. If your power source turns counterclockwise, you'd need a different model rated for CCW rotation. Worth double-checking your drive direction before mounting it up.

Match-up is straightforward here. The model number for this pump is 45VQ50A86B20, and the supplier part number is 433252-2, so it lines up as the same configuration.
