VVS/VVP
The VVS series adopts an advanced variable displacement vane structure, where the rotor position changes relative to the cam ring to regulate flow output. This design allows the pump to supply only the required oil flow, minimizing energy loss and heat generation.
Compared with fixed displacement vane pumps, the VVS series offers superior control, longer service life, and improved system efficiency.
• Long pump life resulting from manufacturing material characteristics, hydrodynamic lubrication of bearings, and hydrostatic balancing of distribution plates.
• Quiet pump operation from 55 to 73 dB(A).
• Simplifies hydraulic circuit by eliminating maximum pressure relief valves and heat exchangers. Pumps can be supplied with various pressure regulators to control the maximum system pressure.
• Standard ISO and SAE mountings.
• Combinations of standard pumps provide flexibility and cost effective pump packages.

Charge pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
The VVS series pumps are variable displacement vane pumps with a built-in pressure compensator. They automatically adjust flow output based on system pressure, ensuring energy-efficient and stable operation.
The main difference lies in displacement range, flow capacity, and power level.
VVS0: Small displacement, light-duty applications
VVS1: Medium-small systems
VVS2: Medium industrial use
VVS3: Large flow and heavy-duty systems
The maximum working pressure varies by size:
VVS0: up to 150 bar
VVS1 / VVS2: up to 100 bar
VVS3: up to 80 bar
VVS pumps are compatible with:
Mineral oil (ISO HM, DIN HLP)
Synthetic fluids such as HFD-V
Proper fluid selection ensures longer service life and stable performance.
The typical speed range is 800 to 1800 r/min, depending on the model and working conditions.
Yes. Thanks to the variable displacement mechanism, the pump only delivers the required flow, reducing energy loss, heat generation, and overall operating costs.
Standard mounting: ISO 3019/2 or SAE flange
Rotation direction: right-hand (clockwise)
No radial or axial load should be applied to the shaft
Proper installation is critical for performance and durability.
They are widely used in:
CNC machine tools
Injection molding machines
Hydraulic power units
Industrial automation systems
Press machinery
Charge pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
