Controls. Mechanical-hydraulic M

The M1R-pump control combines robustness with high precision for direct and reliable machine control. It is mechanically controlled
and can be combined with a fixed, variable or regulating hydraulic motor. The control-specific data is independent of the nominal
pump size.

M1R Mechanical control

Flow direction

By turning the control lever the pump flow rate and direction of flow are controlled via a cam plate. The flow direction of the fluid
depends on
>> the pump direction of rotation
>> the over centre direction of the swash plate.
