Question by: Kurt D on Oct 9, 2025, 11:08 AM
Reckon this pump would hold up alright in a dump truck setup?
Answer by: Customer Support on Oct 11, 2025, 7:58 AM
For dump truck operation, this Vickers vane pump is a solid choice. Its cast iron build is tough enough to handle demanding use, and the Buna-N seals hold up well against hydraulic fluids.
Question by: Travis B on Feb 18, 2026, 11:50 AM
flow rate on this one says 121 liters a minute, is that enough to run heavy equipment like a wheel loader without starving the system?
Answer by: Customer Support on Feb 19, 2026, 12:45 PM
For wheel loader applications, that flow rate is well within the range needed to keep a hydraulic system fed properly. The 4520V50A8 1AD22R is built for exactly that kind of work, and at just over 121 liters per minute it delivers a solid, consistent output for heavy-duty cycles. The cast iron construction helps it hold up under the kind of continuous load that mobile equipment puts on a pump, so you're not going to see it fold under pressure from regular loader operation.
