It is widely used in construction machinery, industrial equipment, metallurgical machinery, plastic machinery, walking machinery, forging, machine tools, shipbuilding, medical treatment, etc.

Product Description
The D-A4VSO pump has the advantages of low noise, small size, good self-priming ability, and high reliability. When applied in a closed system, when the oil pump variable crosses the zero position, there is generally a tray phenomenon in the plunger pump. Only the D-A4VSO pump effectively solves this problem, because the supplementary oil pump and control pump can be connected in series, and the control valve can be integrated on the pump cover, its structure is very compact; In addition, the proportional pumps are equipped with a closed feedback loop with displacement sensors, and their zero position control accuracy is very high.
Widely used in metallurgical industry, forging industry, shipbuilding industry, military ships and other fields.
The D-A4VSO series produced by Deke has specifications of 40, 71, 125, 180, and 250:; The variable forms include constant pressure, constant power, hydraulic, load sensing, proportional, servo, and pressure flow compound control forms; There are open system pumps and closed system pumps.
1、 Product features
a、 Swash plate axial piston pump variable pump b. The flow rate of the hydraulic pump is proportional to the pump speed and displacement c. It can achieve stepless variable by adjusting the angle of the swash plate d. The rated working pressure can reach 35MPa e. Excellent suction characteristics are selected, with a long lifespan and high-precision bearings f. It has compact structural design, light weight, and low noise characteristics g. Static pressure balance shoes improve service life h. Control response is sensitive and equipped with a swash plate angle indicator
