DANA Pump Variable Displacement - S6CV series

S6CV series are variable displacement, axial piston pumps, with swash plate design, for closed circuit hydrostatic transmissions and high pressure applications. The pump can be supplied as single or tandem version and with through drive options for the assembly of auxiliary gear pumps.

Feature | DANA Pump Variable Displacement S6CV

The S6CV series variable piston pumps for closed loop circuits are axial pistons with swash plate design and through drive shaft on option. These pumps have been specifically designed for use in closed circuit hydrostatic transmissions. The delivery is proportional to the rotation speed and the swash plate angle. The delivery increases when swash plate's angle of inclination increases from 0 to maximum position. Inverting the swash plate's angle, the flow direction is inverted. The technical choices allow the new unit to operate at preesures up to 400 bar [5800 psi]
The series offers the following range of controls

HLE Manual lever with feed-back.
HIR Hydraulic proportional with feed-back.
HIN Hydraulic proportional without feed-back.
HER Electric proportional with feed-back.
HEN Electric proportional without feed-back.
HE2 Electric on-off.
HEH Electric proportional with hydraulic emergency override.
