CHARACTERISTIC
◆Swashplate type axial piston variable displacement pump for closed circuit hydrostatic transmission ◆The flow is proportional to the driving speed and displacement and can be infinitely variable; ◆The flow rate increases from zero to its maximum value with the swash plate swing angle; ◆Swing the swash plate over the neutral position can smoothly change the flow direction of the liquid; ◆Multiple variable modes that are easy to match with various control and regulation systems; ◆The pump is equipped with two relief valves on the high pressure oil side to protect the hydrostatic transmission (pump and motor) from overloading; ◆The high pressure relief valve also has the function of oil filling valve; ◆Built-in auxiliary pump is used as charge pump and control pump; ◆The maximum charging pressure is limited by a built-in charging relief valve; ◆Full series with built-in pressure shut-off valve;
Features
Integrated auxiliary pump for the cooking and pilot oil supply Change in flow direction when adjusting the Swashplate through the zero position High-pressure relief valves with integrated feed function With adjustable pressure cut-off as standard Boost pressure relief valve Through drive for attaching additional pumps of the same type
piston pump A4VG series A4VG40 A4VG56 A4VG71 A4VG90 A4VG125 A4VG180 Construction Machinery Parts
1. Product application: excavators, drilling rigs, garden machinery and other small travel machinery up to 4 tons; 2. Product characteristics - Rated pressure PN 210 bar, maximum pressure Pmax 300 bar. -Total power control, short control time, energy saving and high efficiency; -Special "single inlet and four outlet" oil port, which can better meet the small flow rate of multi-loop hydraulic system; -High-quality ductile iron cylinder body and double alloy port plate, which are well suited to the use of light engine; -Flexible power adjustment according to needs, better meet the needs of various working conditions; -Swash Plate structure for hydrostatic transmission in open loop systems; -Flow rate proportional to drive speed and displacement, infinitely adjustable by adjusting the swash plate angle; -Good oil suction performance, low noise level; -Compact and lightweight construction with high power/weight ratio;
