reckon this would work good in a power steering setup on my old pickup?
Answer by: Customer Support on Aug 4, 2025, 6:18 PM
This VICKERS vane pump is designed for power steering applications as well as smaller industrial units, so it should be a good fit.

cast iron build on this one got me curious, how's it hold up in a high-pressure setup, and what kind of flow are we talkin?
Answer by: Customer Support on Feb 25, 2026, 3:13 PM
Cast iron handles the pressure well in this pump. It's built for high-pressure, high-speed conditions, so it's not going to fold under a demanding load. Flow rate comes in at just under 149 liters per minute, which gives you solid output for industrial small units or power steering systems without sacrificing efficiency. The volumetric efficiency on the VQ series is one of its stronger points, so you're not losing much to internal slippage either.
