Product Description
The A4VSO500, A4VSG500 and A4FO500 we developed is the biggest size hydraulic axial piston pump in domestic. The concept of HILEAD A4V series design applies oblique cylinder hole structure, spherical with flow, static pressure balanece, and shaft drive structural design. The hydraulic pump has a high rated working pressure, low noise, good self-priming ability, stable performance alternating load, can withstand the radial force, has multiple forms of variable, adn long working life etc.

HILEAD A4V series hydraulic pump has a variety of variable form of matched control conditions for any hydraulic system applications.

*Proportional flow control-EO2
HILEAD A4V series hydraulic pump use original Rexroth proportional valve and displacement sensor, combined with the National Research Center of Zhejiang University of electro-hydraulic proportional control technology, to achieve stepless regulation of hydraulic pump displacement. Flow control precision parameter: Minimum repeatability linearity deviation ± 0.5% Vg max, ± 1% Vg max. Flow control signal: 0-10VD or 4-20mA optional.
*The pressure/flow/power ratio control-DFE1
HILEAD A4V series hydraulic pump use original Rexroth servo valve, displacement sensor and pressure sensor, combined with the National Research Center of Zhejiang University of electro-hydraulic proportional control technology, achieve stepless regulation of the hydraulic pump flow, pressure and power.
