Tandem Pump
The pressure ratings of tandem pumps are limited by the torque capacity of the drive shaft and the intermediate connecting spline.
Product Description
In order to determine these limitations:
1. Multiply the pressure on each section of the pump by the displacement of each section. This gives the PQ rating for each pump section. The sum of both PQ values must not exceed that given for the type of input drive shaft selected.
2 The PQ rating for the rear pump must not exceed the value given for the tandem spline coupling.
