The enterprise has a technical team and hydraulic pump production equipment. The enterprise adheres to the manufacturing concept of "no best, only better", and its continuous research, development and improvement are only for serving your needs. 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 swash plate structure axial piston variable displacement pump is designed specifically for open circuit hydraulic drive.
The flow rate of the pump is proportional to the speed and displacement of the pump, and the displacement can be continuously adjusted by adjusting the angle of the swash plate.
Structural features:
◆ Excellent suction characteristics, allowing for a nominal working pressure of 35 Mpa
◆ The drive shaft can withstand axial and radial loads
Stacked design with excellent power/weight ratio.
Short control response time and long service life.
◆ Through shaft structure, can form a combination pump.
◆ The installation position is optional, with a swash plate angle indicator.
HF liquid can be used for operation, but the operating parameters may be reduced.
◆ Diverse functional control devices to meet system control requirements.
Application field:
◆ Steel metallurgy and forging machine tools
Ceramic and refractory hydraulic press
◆ Ship and water conservancy and hydropower hoists
Rubber vulcanization machine and papermaking equipment
Petrochemical, construction, and railway machinery
Performance parameters:
◆ Capacity series 40, 71125180250300355500
◆ nominal pressure 35 Mpa; Peak pressure 40 MPa
Control type:
◆ Constant voltage control DR/DRG
Pressure and flow control DFR
◆ Constant power vehicle control LR2
◆ Electronic control EOVEO2
◆ Manual control
◆ Manufacturing MA
Explanation:
The HD-VSO inclined plate axial piston variable displacement pump is designed specifically for open circuit hydraulic drive.
The flow rate of the pump is proportional to its speed and displacement, and adjusting its inclined plate angle can achieve stepless adjustment of displacement.
Features:
◆ Position control swash plate structure, stepless variable, excellent suction characteristics, allowable rated working pressure of 35MPa, low noise, long service life, drive shaft capable of withstanding axial and radial loads, excellent power/weight ratio, modular design, short control response time, through shaft structure, optional position and installation position, can work with HF liquid, but with reduced operating parameters.
