Four quick tools for sizing a hydraulic power pack — pump flow, motor power, reservoir volume and cylinder force. Everything runs in your browser, and the formula is shown so you can check the working. For a full recommended configuration, use the HPU Configurator.
Theoretical flow delivered by a fixed-displacement pump at a given speed.
Electric motor power needed to drive the pump at a working pressure and flow.
Reservoir volume by the common rule of thumb (3–5× pump flow per minute).
Push and pull force a cylinder develops at a given pressure.
Please note
These calculators give preliminary engineering guidance only. Real systems involve duty cycle, oil viscosity, temperature, line losses, safety margins and component tolerances. Always have the final system selection verified by a qualified engineer — or let our team confirm it for you.
