Description Series 42 pumps are advanced hydrostatic units for medium power applications with maximum loads of 415 bar [6017 psi] (28/41 cm 3 ) and 350 bar [5075 psi] (32/51 cm 3 ). You can combine these pumps with a suitable 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.
