Care must be taken so that a shaft will not receive an excess torque load in multiple pump applications.

Since multiple pump applications up to four (4) have been done, various points could receive higher loads than they can transmit

To check for overload all the torques at actual load must be:
1. Compared to the load rating of each input shaft
2. the sum of all units must not exceed the first pump's torque rating

To calculate the actual input torque use the following formula:

TA = TR * ( PA / PR ) * (% Stroke / 100%)

Where:
TA=Actual torque, PA=Actual maximum pressure, TR=Rated torque, PR=Rated working pressure
