Ask A Question

Description & Features

Engineered for high-pressure, high-speed hydraulic circuits, the 35VQ Series Vane Pump, 21 Ring Size, 14 Tooth SAE C Splined Shaft, Outlet in-Line with Outlet, CW Rotation is a single vane pump from Eaton Vickers rated to 3,000 PSI with a displacement of 4.04 and a rated flow of 31.5 GPM at up to 2,500 RPM. The 14-tooth SAE C splined shaft and 2-bolt SAE C mounting flange provide straightforward integration into standard industrial drive arrangements.

Port connections consist of SAE 4-bolt flange ports, a 2" inlet and 1-1/4" outlet, with the outlet positioned in-line with the inlet. Buna-N seals support compatibility with standard hydraulic oils across a broad range of service conditions. Clockwise rotation is fixed for this configuration. Typical applications include metal cutting equipment, dump trucks, wheel loaders, plastic injection molding machinery, and oil and gas service equipment.

Question by: Billy T on Jun 14, 2025, 7:18 PM
got a 2-bolt SAE C mount on my setup. is this pump the right flange and what size are the ports?
Answer by: Customer Support on Jun 16, 2025, 6:52 AM
It uses a 2-bolt SAE C mounting flange and it comes with SAE 4-bolt flange ports. Port sizes are 2 inch inlet and 1-1/4 inch outlet.
Question by: Lyle G on Nov 5, 2025, 6:24 AM
pump's rated at 2500 RPM -- is that the max or is there some headroom above that for short bursts?
Answer by: Customer Support on Nov 6, 2025, 7:12 PM
2500 RPM is the rated operating speed for this pump, and that's the number you want to stay at or below during normal use. Running above the rated speed, even briefly, puts extra stress on the vanes and internal components and can shorten the service life faster than you'd expect. For consistent, reliable output you're better off keeping it right at or under that mark rather than pushing past it.
