Question by: Hank G on Oct 16, 2025, 10:42 AM
got a compact hydraulic power unit for a small press, would this 2520VQ pump be a decent match or is it more of a steering pump
Answer by: Customer Support on Oct 17, 2025, 4:31 PM
Built for power steering systems and small industrial units, it also fits light press applications. It is a 2520VQ Series double vane pump meant for high-pressure, high-speed hydraulic circuits where you want steady output in a compact setup.
Question by: Earl H on Jul 27, 2025, 6:35 AM
what kind of applications is this pump actually built for? asking cause we run a few small hydraulic press setups and trying to figure out if it fits what we got
Answer by: Customer Support on Jul 28, 2025, 11:03 AM
Cast iron body, Buna-N seals, and a flow rate pushing nearly 149 litres per minute puts this pump squarely in the range for small industrial units and light press work. Power steering systems are another common fit. If your press setups fall on the smaller, lighter end of the load spectrum, this is the kind of pump that holds up well under that sort of regular demand without a lot of fuss.
Question by: Hugh M on May 21, 2025, 7:51 AM
I'm looking for a replacement pump for my power steering system. How can I be sure this Vickers pump will be a good fit?
Answer by: Customer Support on May 23, 2025, 6:49 AM
This pump is commonly used in power steering setups, along with smaller industrial units and light press applications. To ensure proper fit, verify the dimensions listed on your current pump match those of the Vickers 2520VQ21A5 1AA20.
