Introduction to VDC Hydraulic Pump
VDC hydraulic pump is a high-pressure variable vane pump , The detailed introduction is as follows:
Features
* Efficient and stable high-pressure operation: It adopts a unique pressure control and pressure balance structure, combined with
an innovative three-point ring support system, enabling stable and efficient operation under high pressure up to 14MPa
(2000psi).
* Low vibration and noise: Multiple anti-vibration and noise-reduction structures are applied, such as the three-point support
system for the control piston and offset piston. This enhances the stability of the oil ring, effectively reducing vibration
and noise for quiet operation.
* Fast response and high-precision action: The new stopper structure solves the displacement problem of the oil ring, improving
responsiveness. It achieves high-precision action during startup, shutdown, and load changes.
* Accurate characteristics and stable discharge volume: The pressure-controlled structure in the form of a pressure compensator
ensures a highly stable rated discharge volume even in the high-pressure range, with stable flow characteristics.
* Efficient operation and low power loss: The new mechanical design and high-precision processing technology reduce power loss,
especially during full cut-off, improving operational efficiency.
* Easy maintenance and operation: The pressure adjustment and discharge volume adjustment structures are located on the same side
of the pump, facilitating maintenance and operation.

Technical Parameters
* Flow range: It varies by model. For example, the flow rate of VDC-1 is 30L/min at 1800min⁻¹, VDC-2 is 54L/min, and VDC-3 is
120L/min.
* Pressure adjustment range: For instance, the pressure adjustment range of VDC-2A-1A2-20 is 1.5-3.5MPa, and that of
VDC-2A-1A5-20 is 7-14MPa.
* Installation method: Multiple installation methods are available, including flange type (B) and foot-mounted type (A).
* Rotation direction: Right rotation (clockwise direction) when viewed from the shaft.
* Hydraulic oil requirements: When used below 7MPa, it is recommended to use hydraulic oil equivalent to ISO VG32 (viscosity
index above 90); when used above 7MPa, high-quality petroleum-based hydraulic oil equivalent to ISO VG68 (viscosity index above
90) is recommended.

Application Fields
The VDC series hydraulic pumps are widely used in occasions requiring high pressure and high-precision control, such as industrial
machinery, machine tools, and mobile hydraulic systems of vehicles.
