The product from the U.S. Department,introduced the 20 series hydraulic transmission technology and  manufacturing, 20 Series variable piston pump swash plate structure has changed traffic. For closed -loop hydrostatic drive  system . The pump is a charge pump with variable displacement pump , the motor is a quantitative variable motor with  integrated motor or valve block. Variable control manual (MDC) \ hydraulic (HDC) and electric (EDC) controls , effectively control  the flow of oil output , direction and power . Pump output flow is proportional to the spindle speed and displacement . Displacement of variable , depending on the inclination of the swash plate , and can regulate between zero to maximum . The  output flow of the pump swash plate angle by changing the sign ( i.e., both sides of the median ) and changed, but must  transition through the swash plate position . This series of pumps - wide speed range of hydraulic gear motors composed ,  reliable, easy to operate , in supporting the production of concrete delivery tanker , has been widely used .
PV20 Series variable piston pump features:
1 , 20 series axial variable piston pump manufacturing quality , simple operation
2 , the spindle bearings are tapered Gunzi bearings can withstand greater external axial force
3 , additional pumps can be connected in series
4, mechanical manipulation, to control the hydraulic servo can keep the displacement angle of the swash plate and the  corresponding displacement
5 , the control lever is released , the swash plate is automatically returned to the neutral position, the flow becomes zero
6 , good spindle seal, even at high temperature environment of the housing pressure does not leak  7 , can be connected to the servo valve function regulator and remote control systems  8 , the formation of the plunger for easy maintenance , the use of standard tools can be removable, so the parts and components are pass  Pictures Â
