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.
