Hydraulic power and motor size calculator

Hydraulic power and drive motor size from pressure and flow.

Calculating…

How it's calculated

P_hyd [kW] = p [bar] × Q [L/min] ÷ 600 P_motor = P_hyd ÷ η_overall

Any hydraulic power not doing useful work, for example flow over a relief valve, turns into heat in the oil. That is why a system dumping over relief runs hot.

Choose the next standard motor size up from the calculated power.
