Question by: Dwight W on Jan 20, 2026, 11:54 AM
Got a 1-1/4 keyed shaft on my motor, will this pump bolt right up to it?
Answer by: Customer Support on Jan 21, 2026, 8:07 PM
Perfect match there. Your 45VQ50 comes with a 1-1/4 straight keyed shaft that'll connect directly to your motor shaft. Just make sure your motor rotation is clockwise since that's how this unit is configured.

How should the 45VQ Series Vane Pump be installed to ensure proper rotation direction?
Answer by: Customer Support on Aug 28, 2025, 9:06 AM
Make sure the pump is set up for clockwise rotation, as specified. The outlet should be aligned in-line with the outlet, and the 1-1/4 straight keyed shaft should be secured properly. This setup will help in achieving optimal performance.
