Product Questions & Answers (2)

Question by: Norm H on Oct 2, 2025, 3:58 PM
Can this pump handle continuous duty in a power steering setup, or is it more for intermittent use?
Answer by: Customer Support on Oct 4, 2025, 6:21 AM
This Vickers vane pump is built for high-pressure and high-speed applications, so it should hold up well in a power steering system. Its durable cast iron construction also contributes to a longer operating life.
Question by: Duane D on Dec 4, 2025, 7:15 AM
Running a small hydraulic press off this pump, does that flow rate hold up for that kind of setup?
Answer by: Customer Support on Dec 5, 2025, 7:25 PM
At roughly 148.7 liters per minute, this pump puts out more than enough flow for small press applications. That's actually one of the listed use cases for this unit, right alongside power steering systems and small industrial setups. The cast iron construction keeps it solid under the kind of load cycling a press puts it through, and the volumetric efficiency is built to stay consistent over time rather than drop off after a few hundred hours.
