Structural & Performance Characteristics
-
Hydrostatic support of the cradle bearings for stable operation
-
Connection for measuring sensor on the high-pressure port
-
Low noise level and low pressure pulsation for quiet and smooth operation
-
High efficiency and strong resistance against cavitation, suction pressure loss and case pressure peaks
-
Universal through drive for versatile installation
-
Flow is proportional to drive speed and displacement; infinitely variable by adjusting swashplate angle
