The fundamental elements on which the choice of pump drive is based are:
- number and type of hydraulic pumps to be applied
- max torque absorbed by the pump (or by the group of pumps) on each output of the pump drive
- max power entering the pump drive
Depending on the overall dimensions of the pumps, complete with pipes and pipe fittings, it is possible to establish the minimum distance between the pumps themselves. Comparing these values with the values forseen in the catalogue for the output shafts, it is possible to make a choice of type.
Verify that the torque value of each output is kept below the max value shown in the catalogue for the chosen pump drive.
In cases of use in important industrial systems or in marine applications, it is necessary to bear in mind relevant safety factors.
Also verify that the rotation speed of input shaft isn’t more than the max indicated in the catalogue.
In the case of pump drives with clutch BD or BDS verify that the max input torque is at least 20% below the max transmittable from the clutch.
