Eternal Hydraulic A7V Axial Variable Displacement Piston Pump
Variable displacement pump, axial piston bent axis design, for hydrostatic transmissions in open circuits.The flow is proportional to the drive speed and the displacement and is steplessly variable at constant drive speed.
Comprehensive program of control devices for every control and regulating unction. Simplified high performance rotary group with enhanced technical data and well-proven spherical control area.
Robust roller bearings for high loads. Hydrostatic unloading of bearings possible for continuous pressures up to 400 bar. Operation on both mineral and fire-resistant fluids. Improved port plate design and compact construction reduces noise level by 5 dBA.

APPLICATION
Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine and other hydraulic systems.
The characteristics of Eternal Hydraulic variable displacement piston pump:
· Completely interchangeable with original
· Very competitive price
· Low-noise, high efficiency, high reliability, long life
· Small size, high power density
· Excellent oil absorption properties.
· Drive shaft can withstand the axial and radial loads
· SAE and ISO mounting flange
· For pass-axis structure, and for multi-loop system
