Ask A Question

Description & Features

Rated for up to 3000 PSI and a maximum speed of 2400 RPM, the 35VQ Series Vane Pump is built for demanding, high-pressure hydraulic applications across metal cutting, plastic injection molding, oil and gas, dump trucks, and wheel loaders. It features a 35 ring size, a 1-1/4" straight keyed shaft, and clockwise rotation, with the inlet port positioned 90 degrees counterclockwise from the outlet.

Manufactured by Eaton Vickers, this single vane pump delivers a rated flow of 53.6 GPM and a displacement of 6.88 in³/rev. Mounting uses a 2-bolt SAE C flange, with SAE 4-bolt flange ports sized at 2" inlet and 1-1/4" outlet. Buna-N seals provide reliable fluid compatibility in standard hydraulic oil service. The design supports longer service life and strong volumetric efficiency under continuous high-speed, high-pressure duty cycles.

Question by: Frank R on Oct 19, 2025, 11:18 AM
trying to swap out a worn pump, what all do i need to match up on this 35VQ one so it bolts in right
Answer by: Customer Support on Oct 21, 2025, 6:52 AM
The big items to line up are the 2-bolt SAE C mounting flange, the shaft style and size (1-1/4 inch straight keyed), and the port setup. This model uses SAE 4-bolt flange ports with a 2 inch inlet and a 1-1/4 inch outlet, and the inlet is clocked 90 degrees counterclockwise from the outlet. Rotation is clockwise.

Got a dump truck running a 35VQ pump that finally gave out on me. This one a straight swap, or are there fitment things I need to check before ordering?
Answer by: Customer Support on Mar 9, 2026, 3:31 PM
For a direct replacement, the key things to match up are the shaft size, rotation, and port configuration. This pump runs a 1-1/4" straight keyed shaft, clockwise rotation, and the inlet sits 90 degrees counterclockwise from the outlet. Mounting is a 2-bolt SAE C flange, with a 2" SAE inlet port and a 1-1/4" SAE outlet. If your existing pump matches those specs, you're looking at a drop-in fit.
Question by: Rusty S on Aug 5, 2025, 3:13 PM
Will this pump work okay for plastic injection molding machines, or is it too much pump?
Answer by: Customer Support on Aug 7, 2025, 11:21 AM
This 35VQ series vane pump is definitely suitable for plastic injection molding, as that's one of its listed applications. It's built for the demanding, high-pressure hydraulic needs of that kind of equipment, among others.
