4.1 Drive units
If you are using motor-driven pumps with one drive shaft, the direction of flow is selected by determining the
rotational direction of the drive motor, such as an electric motor or hydraulic motor.

4.2 PTO drive
If you are using tractor driven pumps with two drive shafts, connect either the upper or lower the cardan
shafts thus determining the direction of flow.

Risk of noise and vibration due to incorrect connection and orientation of the cardan
shafts
Generation of noise and vibrations can cause impairment of communication and discomfort. Therefore
please read the operating instructions of the cardan shaft manufacturer and follow the instructions. Observe
permissible flex angle and minimum profile overlapping of the cardan shafts.
Risk of crushing due to seized couplings of the cardan shafts
•
In order to prevent the coupling from seizing, make sure assembly is clean and make sure that the
PTO shaft is in flawless condition.
•
Wear protective gloves.
