The concept of HL-A4V series design applies oblique cylinder hole structure, spherical with flow, static pressure balance, and shaft drive structural design. The hydraulic pump has a rated working pressure, low noise, good self-priming ability, stable performance alternating load, can withstand the radial force, has multiple forms of variable, and long working life etc., the performance fully meet the imports of the same series of product standards. HL-A4VSO series hydraulic pumps are suitable for open circuit hydraulic drive; The HL-A4VSG series hydraulic pumps suitable for closed circuit hydraulic drive; the HL-A4FO series hydraulic pump are suitable for open circuit hydraulic drive. 


HL-A4V系列液压泵变量形式齐全,针对任何液压系统应用工况可提供匹配的控制方式。 控制方式:压力控制DR,功率控制LR2,手动控制MA,液压控制HD,流量电比例控制EO2,流量伺服控制HS1,压力/流量比例控制DFE1。

HL-A4V series hydraulic pump has a variety of variable form of matched control conditions for any hydraulic system applications. Control method: pressure control-DR, power control-LR2, manual control-MA, hydraulic control-HD, flow electro-proportional control-EO2, traffic servo control-HS1, pressure / flow proportional control-DFE1.


* 流量比例控制EO2

选用德国Rexroth原装的比例阀及位移传感器,结合浙江大学国家电液研究中心的比例控制技术,实现对液压泵排量无级调节。流量控制精度参数;最小可重复性±0.5%Vgmax,线性度偏差±1%Vgmax:流量控制信号:0-10VD或4-20ma可选。

* Proportional flow control –EO2

Hilead HL-A4V series hydraulic pumps 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% Vgmax, ± 1% Vgmax. Flow control signal: 0-10VD or 4-20mA optional.


* 压力/流量/功率比例控制DFE1

选用德国Rexroth原装的伺服阀、位移传感器及压力传感器,结合浙江大学国家电液研究中心的比例控制技术,实现对液压泵流量、压力及功率无级调节。

* The pressure/flow/power ratio control – DFE1

Hilead HL-A4V series hydraulic pumps 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.
