Product Description

◆ Swash-plate type variable displacement axial piston pump, designed specifically for open-circuit hydraulic drives.

◆ The pump flow rate is proportional to its rotating speed and displacement; stepless displacement adjustment can be realized by changing the swash plate angle.

Structural Features

◆ Excellent suction performance, rated working pressure up to 35 MPa

◆ Drive shaft can bear both axial and radial loads

◆ Modular stacked design, favorable power-to-weight ratio

◆ Short control response time and long service life

◆ Through-drive shaft design, available for composite pump assembly

◆ Optional mounting positions, fitted with swash plate angle indicator

◆ Compatible with HF fluids, with reduced operating parameters accordingly

◆ Diverse control devices available to satisfy different system control requirements

Application Fields

◆ Iron & steel metallurgy and forging machine tools

◆ Hydraulic presses for ceramics and refractory materials

◆ Marine engineering and water conservancy & hydropower hoists

◆ Rubber vulcanizing machines and papermaking equipment

◆ Petrochemical, construction and railway machinery

Performance Parameters

◆ Displacement sizes: 40, 71, 125, 180, 250, 300, 355, 500

◆ Rated pressure: 35 MPa; Peak pressure: 40 MPa

Control Types

◆ Constant pressure control: DR / DRG

◆ Pressure & flow control: DFR

◆ Constant power control: LR2

◆ Electronic control: EO / EO2

◆ Manual control

◆ MA control

Remarks

◆ HD-VSO swash-plate variable displacement axial piston pump, specially designed for open-circuit hydraulic drives.

◆ Pump flow is proportional to rotating speed and displacement; stepless displacement regulation can be achieved by adjusting the swash plate inclination angle.

Features

Position-controlled swash plate structure, stepless variable displacement, superior suction performance, rated working pressure of 35 MPa, low noise, long service life. The drive shaft withstands axial and radial loads, with good power-to-weight ratio, modular design, short control response time, through-drive shaft structure, optional installation orientation. It can work with HF fluids, while operating parameters will decrease.
