Question by: Donna G on Dec 3, 2025, 1:19 PM
pump's rated at 21.5 flow and 3000 PSI max -- is that enough for running a wheel loader hydraulic system hard all day, or is this more of a light-duty setup?
Answer by: Customer Support on Dec 5, 2025, 7:50 AM
For wheel loader applications, this pump is built for exactly that kind of work. The 25VQ series handles high-pressure, high-speed conditions, and the 3000 PSI maximum pressure rating puts it in solid territory for demanding loader circuits. At 21.5 GPM rated flow and a 2700 RPM speed rating, it can sustain the output needed for continuous heavy-duty cycles. The Buna-N seals hold up well under the kind of varied operating conditions you see in that environment, so longevity shouldn't be a concern if the system is properly matched.
