Power supply suitable for your machine's needs
Tank, pump, electric motor, filtration and control elements are evaluated together. The appropriate structure is determined according to your working pressure, flow rate and cycle information.
| Tank capacity | According to your project |
|---|---|
| engine power | According to pressure and flow |
| Pump type | Gear / vane pump options |
| flow rate | According to duty cycle |
| Working pressure | According to application requirement |
| Valve & control group | Selection suitable for function |

Calculation assumptions and formulas
One cylinder with a direct axial load; g = 9,80665 m/s². Assumptions: 15% pressure allowance and 85% overall power efficiency. Q × 3 minutes is only an initial tank estimate; thermal calculations and duty-cycle checks are required.
A = πD²/4 (retraction: π(D²−d²)/4), Q = A × stroke × 60 / (time × 10⁶), p = load × g × 10 / A × 1,15, P = p × Q / (600 × 0,85).
Basic SI formulas: Parker ↗A start for preliminary design.
