PUMP CALCULATOR
Pump Flow and Displacement
Calculated flow38.64 L/minQ = displacement × speed × efficiency ÷ 1000
Required displacement: 28.99 cm³/rev
RFQ PREPARATION TOOLS
Check basic hydraulic relationships before selecting or replacing a component.
These calculators support preliminary review. Use manufacturer data, measured system conditions and qualified engineering approval for final component selection.POWER CALCULATOR
Hydraulic and Shaft Power
Required shaft power16.47 kWHydraulic power ÷ total efficiency
Calculated hydraulic output: 14.00 kW. Select a drive with appropriate service margin and manufacturer approval.
CYLINDER CALCULATOR
Extension and Retraction Force
Ideal extension force125.66 kNPressure × full piston area
Ideal retraction force: 86.25 kN. Actual force is lower after friction, pressure loss and safety factors.

Conversions are rounded for display. Keep the original engineering units in the RFQ and drawing.
What these calculators cannot confirm
A matching calculated value does not confirm shaft, flange, control, ports, voltage or installation fit.
Acceleration, pressure peaks, heat, line losses, duty cycle and control stability require system analysis.
Final design and commissioning must follow applicable machine standards and qualified engineering review.
FORMULAS AND ASSUMPTIONS
Record the inputs behind every calculated value.
A result is reproducible only when units, efficiencies and operating conditions are retained with it. Default values are examples, not recommendations for a machine.| Calculator | Core relationship | Important omitted effects | Use in an RFQ |
|---|---|---|---|
| Pump flow | Displacement × rotational speed × volumetric efficiency | Speed limits, leakage change, charge conditions and control behavior | State desired flow and the speed/efficiency assumptions |
| Pump power | Pressure × flow, adjusted for total efficiency | Starting torque, pressure peaks, drive losses and service factor | State working and peak pressure separately |
| Cylinder force | Pressure × effective piston area | Friction, side load, buckling, back pressure and acceleration | State bore, rod, stroke, mounting, load direction and safety factor |
| Unit conversion | Fixed mathematical conversion factors | Source measurement tolerance and rounding | Keep the original unit beside the converted value |
Hydraulic Match calculators run in the browser and provide arithmetic estimates only. They do not read machine data, select a component or account for applicable design standards. Independent engineering review remains necessary where failure could affect people, equipment or production.
Use the result to prepare a better RFQ.: Send the original component code together with actual pressure, flow, speed, dimensions and application conditions.
