These pumps can be combined with a suitable Sauer-Sundstrand 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 tillable swash plate to vary the pump's displacement. Reversing the angle of the swash plate reverses the flow of oil from the pump, and thus reverses 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 modes of operation. Series 42 pumps utilize a cradle swash plate design with a hydraulic servo control cylinder. Control is provided through a compact servo control system. A choice of servo controls are available.These include mechanically- or electrically-actuated feedback controls, hydraulic or electric proportional controls, and a three-position electric control. These controls are designed for low hysteresis and responsive performance.- Series 42 - Advanced Technology Today- 2 Sizes of Variable Displacement Pumps- Complete Family of Control Systems- Proven Reliability and Performance- Optimum Product Configurations- Compact Profile- Quiet OperationWorldwide Sales and ServiceTechnical DataTable of values (theoretical values, without efficiency and tolerances; values rounded)Size28324151Displacement cm3[in3]28 [1.71]31.8 [1.94]40.9 [2.50]51 [3.11]mass moment of inertiakg•m2 [lbf•ft2]0.0018[0.0013]0.0019[0.0013]0.0036[0.0027]0.0038[0.0028]type of front mounting flangeSAE BPort connectionsSAE-twin ports, radialsystem pressure regulationbar [psi]140-415[2030-6017]140-345[2030-5003]140-415[2030-6017]140-345[2030-5003]Displacement limitersOptioninput shaft optionsSplined, Round Straight Keyauxiliary mounting padSAE A (9 tooth and 11 tooth) SAE B (13 tooth and 15 tooth)Control optionsMDC, FNR, NFPH, NFPE, HC-EDC, EDCfiltration configurationSuction or charge pressure filtrationloop flushingOptionweight kgf [lbf ]34.5 [76]34.5 [76]42 [92]42 [92]
