Product Questions & Answers (3)

Question by: Cody H on Dec 12, 2025, 2:35 PM

got a machine set up for a 2-bolt SAE B mount. will this pump bolt right up and are the ports the flange style ones?

Answer by: Customer Support on Dec 13, 2025, 9:34 PM

It uses a 2-bolt SAE B mounting flange and it comes with SAE 4-bolt flange ports. Port sizes are 1-1/2 inch inlet and 1 inch outlet, so it matches that flange-port style setup.

Question by: Hugh C on Nov 21, 2025, 6:08 PM

pump puts out 31.5 GPM at what pressure, and is that continuous or just peak?

Answer by: Customer Support on Nov 23, 2025, 5:45 PM

Rated flow on this unit is 31.5 GPM, and the maximum pressure rating is 3000 PSI. That 3000 figure is the rated ceiling for the pump, not a sustained operating target. For most industrial setups, running comfortably below that ceiling is what gets you the longer service life Eaton Vickers built this series around.

Question by: Dale W on May 8, 2025, 7:37 PM

What kind of machines does this vane pump usually go in?

Answer by: Customer Support on May 10, 2025, 3:50 PM

This pump is frequently used in applications like oil and gas equipment, metal cutting machinery, dump trucks, wheel loaders, and plastic injection molding systems.
