Description & Features

Designed for power steering systems and compact industrial press applications, the 30VQ Series Vane Pump, 28 Ring Size, 7/8 Straight Keyed Shaft, Outlet Opposite Outlet, CCW Rotation is an Eaton Vickers single vane pump built to handle high-pressure, high-speed duty cycles. With a displacement of 5.5 and a rated flow of 42.85, it operates at up to 2000 PSI and 2000 RPM, making it well suited for demanding hydraulic circuits in small industrial units.

The pump features a 7/8 straight keyed shaft, counterclockwise rotation, and an outlet port positioned opposite the inlet, a configuration that simplifies installation in specific circuit layouts. Buna-N seals are standard, and the unit carries no special modifications from baseline configuration. Long service life and strong volumetric efficiency are consistent characteristics of the 30VQ series across its application range.

Question by: Shane C on Jun 21, 2025, 11:46 AM
pump says CCW rotation on the shaft end, just want to make sure I got that right before I go bolting it up. that mean looking at it from the back or the front?
Answer by: Customer Support on Jun 23, 2025, 8:25 AM
Rotation direction on vane pumps is always called out from the shaft end, so you're looking straight at the end where the shaft sticks out. CCW on this one means the shaft turns counterclockwise when viewed from that end. Worth confirming before you couple it up, because running one of these backwards won't move fluid the way you need it to.
Question by: Jimmy B on Feb 26, 2026, 7:24 PM
got a pump tag that reads 30VQ28A-1A20-L. is that the same unit you’re selling here?
Answer by: Customer Support on Feb 28, 2026, 8:35 AM
Match the model number and it lines up. The pump is an Eaton Vickers 30VQ Series single vane pump with model 30VQ28A-1A20-L, 28 ring size, 5.5 displacement, CCW rotation, and a 7/8 straight keyed shaft.
Question by: Donna H on Sep 18, 2025, 5:01 PM
I'm replacing a 30VQ pump, and need to know if this one's rotation is counter-clockwise?
Answer by: Customer Support on Sep 20, 2025, 12:29 PM
This 30VQ series vane pump is built with CCW rotation.
