Hydvic Hydraulic Supply 42R28 42R32 42R41 42R51 42L28 42L32 42L41 42L51 Sauer Danfoss piston pump
Series 42 pumps are advanced hydrostatic units for medium power applications with maximum loads of 415 bar [6017 psi] (28/41 cm3) and 350 bar [5075 psi] (32/51 cm3).
You can combine these pumps with a suitable Sauer-Danfoss motor or other products in a system to transfer and control hydraulic power.
The Series 42 variable displacement pump is a compact, high power density unit, using the parallel axial piston/slipper concept in conjunction with a tiltable swashplate to vary
the pump's displacement.
Reversing the angle of the swashplate reverses the flow of fluid from the pump, and reversing the direction of rotation of the motor output. Series 42 pumps provide an
infinitely variable speed range between zero and maximum in both forward and reverse. Series 42 pumps use a cradle swashplate design with a hydraulic servo control cylinder.
Control is provided through a compact servo control system. A variety of servo controls are available. These include mechanically- or electrically-actuated feedback controls,
hydraulic or electric proportional controls, and a three-position.
