Question by: Hugh M on Sep 28, 2025, 9:54 AM
got a unit that needs a clockwise pump, 7/8 keyed shaft. is this one set up that way and where’s the outlet at
Answer by: Customer Support on Sep 30, 2025, 8:55 AM
For rotation and fit, you’re looking at a clockwise rotation pump with a 7/8 straight keyed shaft. The porting is the opposite outlet style, meaning the outlet is positioned opposite the inlet to help with routing in tighter layouts.
