Features:

Hydraulic pumps are well engineered and easy to handle.

The pumps can be connected with other additional pumps.

Upon release of the control handle, the swash plate automatically returns to zero position and

the flow reduces to zero.

High case pressures can be achieved without leakage even at the lowest temperatures

by using suitable shaft seals.

The servo valve arrangement offers the facility to incorporate function regulators and remote

control systems.
