| 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; |
The characteristics of Eternal A4VG pump:
1. The capacity of the pump is in proportion to its rotating speed and displacement; the stepless adjustment of the displacement
can be materialized by regulating the swivel angle of its swash plate.
2. With through-shaft structure, able to form combination pump.
3. Position constraint return mechanism.
4. Spherical flow distribution, the piston is inclined around the shaft.
5. Equipped with swivel angle indior of swash plate.
6. Stepless variable displacement.
7. Excellent suction performance.
8. Rated working pressure of 35MPa.
9. Fast control response.
10. Low noise.
11. Long lifespan.
12. Excellent power/weight ratio.
13. Modular design.
14. The drive shaft is able to bear the axial and radial load.
15. Optional installation position.
16. It can operate with HF fluid to lower the operating parameter.
17.Completely interchangeable with original
Eternal products including Piston Pump, Vane Pump, Gear Pump, Hydraulic Valve, Hydraulic Motor, Electric Motor, Oil Cooler, Accumulator and other hydraulic accessories etc
Hydraulic Piston Pump Series including CY, A2F, A2FO, A7V, A4V, A10V Series, which is the same as Orignal Rexroth, the same appreance, mounting size and working perofrmance.
The products are widely used in machine tool, forging machinery, metallurgy machinery, engineering machinery, mine machinery and other hydraulic systems. They also can be used as hydraulic motors if the valve plate is changed into motor type.
