Product manual
 
The D-A4VSO pump has the advantages of low noise, small size, good self-priming capability and high reliability. In the closed system application, the piston pump has a pallet phenomenon when the oil pump variable crosses the zero position. The D-A4VSO pump can effectively solve such problems. The charge pump and the control pump can be connected in series, and the control valve can be integrated in the pump. The cover is very compact in structure; in addition, the proportional pump has a closed feedback loop of the displacement sensor, and its zero position control accuracy is very high.
 
Widely used in: metallurgical industry, forging industry, shipbuilding industry, military vessels and other fields.
 
The D-A4VSO series produced by Dirk has 40, 71, 125, 180, 250: variable forms: constant pressure, constant power, hydraulic, load sensing, proportional, servo, pressure flow combined control; open system Pumps and closed system pumps.
 
First, product features
 
a, swashplate axial piston pump variable pump b, hydraulic pump flow rate is proportional to the pump speed and displacement c, can be achieved by adjusting the swash plate angle to achieve a stepless variable d, rated working pressure can reach 35MPa e, excellent Inhalation characteristics, long life, high-precision bearing f, compact structure, light weight, low noise characteristics g, static pressure balance sliding shoe to improve service life h, control response sensitivity, swash plate angle indicator
