High Quality Sauer Mf20 Mf21 Mf22 Mf23 Mf25 Hydraulic Axial Piston Motor

Original MF20  MF21  MF22  MF23 Hydraulic Piston MotorProduct DescriptionHydraulic Sauer-Sundstrand axial piston motor MF20, MF21, MF22, MF23, MF24, MF25, MF26, MF27Description Closed circuitSeries 20Size: 20, 21, 22, 23, 24, 25, 26, 27Nominal pressure 210 bars, Maximum pressure 350 bars. The Sauer MF axial piston variable displacement motors, Series 20, are of swash plate construction with variable flow capability suitable for hydrostatic transmissions with closed circuit. The flow rate is proportional to the motors driven speed displacement, which, in turn, is determined by the swash plate angle. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement position. These units and parts are fit, form and function replacements for Sauer-Sundstrand series 20 components. - Suitable for a variety of applications- Multiple displacements and options available- 8 different frame sizes- Engineered to provide a long service life and reliability- Fixed displacement motor can be operated in either direction of rotation- Multiple drive shaft options and control options- Heavy duty bearings and shafts- Easily serviceable- Replacement parts also available- Direct replacements for Sauer-SundstrandFeatureThe full-length shaft with a high efficient tapered roller bearing arrangement offers a high loading capacity for external radial forces. Additional motors can be built on. The hydro-mechanical servo displacement control maintains the selected swash plate position and hence motor displacement.Upon release of the control handle, the swash plate automatically returns to the null position and the flow become zero.High case pressures can be archived without leakage even at the lowest temperature by using suitable shaft seals. The servo valve arrangement offers the facility to incorporate function regulators and remote control system. Axial piston units are designed for easy servicing, complete dismantling and reassembly can be carried out standard hand tools, and all components or sub-assemblies are replaceable.Servo Displacement Control (Linear response)Regular by control handle on the servo valve, the swash plate can be infinitely varied in both direction with the help of the servo system.The motor displacement resulting from any control handle position can be established using figures (5a - 5c).The angle of the control handle for stroke initiation and for the final position of the stroke can vary from unit to unit within the range of the tolerance band. Product ParametersTable of values (theoretical values, without efficiency and tolerances; values rounded)SizeDimensionSauer-Sundstrand MF motorMF20MF21MF22MF23MF24MF25MF26MF27Max. displacementcm333,351,669,889,0118,7165,8227,3333,7Max. flowdm3min-1119,5159,9196,1230,5278,9348,1429,59557,24641488Charge motorcm312,312,318,0318,0318,832,832,865,5Max. pressureMPa35Nominal pressureMPa21Max. pressure of controlMPa3,5Charge pressureMPa0,8 - 2,0Max. pressure in caseMPa0,25 continuous 0,5 intermittentMaximum speed +min-135903100281025902350210018901670Minimum speedmin-1500Nominal speedmin-11500Kinematic viscosity range of working fluid- starting- operating- optimum  mm2s-1  100012 - 60025 - 35Kind of working fluid mineral oilOperating temperatureoC- 40 to + 50Max. temperature of working fluid in tankoC80Purity of working fluidµm10Maximum swash plate angleo± 18 oWeightkg3035404770124152197DimensionsCompany ProfileApplicationRelated Product   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
