Input Torque
The Torque M(Nm) that is available to drive a hydraulic pump from a motor or engine can be calculated as follows:-
!) Power N (kW), this can range from 0.25 to 55kW for Hydraproducts power pack range.
2) Pump Speed n, for AC Motors this is commonly 1450 or 2850rpm
Then press M to calculate, this will be shown in the result box.
Useful conversions factors:
1kW = 1.34hp
1Nm = 0.737 lbf.ft = 141 oz.in
