35VQ Series Vane Pump, 35 Ring Size, 1-1/4 straight Keyed Shaft, Outlet in-Line with Outlet, CCW Rotation

Description & Features

Rated for continuous duty at up to 3000 PSI and 2400 RPM, this Eaton Vickers 35VQ Series Vane Pump is built for demanding high-pressure, high-speed hydraulic circuits. The 35 ring size configuration delivers a displacement of 6.88 in³/rev with a rated flow of 53.6 GPM, making it well-suited for metal cutting machinery, plastic injection molding equipment, dump trucks, and wheel loaders.

The pump features a 1-1/4" straight keyed shaft with counterclockwise rotation and inlet/outlet ports positioned in-line. Mounting is via a 2-bolt SAE C flange, with SAE 4-bolt flange ports sized at 2" inlet and 1-1/4" outlet. Buna-N seals are standard.

Question by: Travis R on Mar 7, 2026, 6:17 PM
runs at 2400 RPM, but what kind of flow are we actually looking at out of this thing?
Answer by: Customer Support on Mar 9, 2026, 7:33 AM
At rated conditions, you're getting 53.6 GPM out of this pump. That's a solid output for a single vane unit, and the 35 ring size is built to handle the volume without sacrificing efficiency. Pair that with a 3000 PSI max pressure rating and it holds up well in demanding hydraulic circuits.
