VVP1/VVP2/VVP3
The VVP1, VVP2, and VVP3 hydraulic variable vane pumps are engineered for high efficiency, stable pressure control, and long service life. Designed with a pressure-compensated variable displacement mechanism, these pumps automatically adjust output flow according to system demand, making them an ideal solution for modern energy-saving hydraulic systems.
• 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 VVP series is a variable displacement vane pump with a built-in pressure compensator. It automatically adjusts flow output according to system demand, helping improve efficiency and reduce energy consumption. If you are upgrading from a fixed pump, feel free to contact us for matching models.
The difference mainly lies in flow capacity and application range:
VVP1: Small to medium systems
VVP2: Medium industrial applications
VVP3: High flow and heavy-duty systems
Send us your technical requirements, and we can recommend the most suitable model.
VVP pumps are designed for medium pressure hydraulic systems, typically up to 70–140 bar depending on the model. For exact specifications, please share your working conditions with us.
Yes, VVP pumps can replace many well-known brands such as Yuken and Daikin Industries vane pumps. Provide your original model number, and we will confirm compatibility.
VVP pumps are compatible with:
Mineral hydraulic oil (ISO HM / DIN HLP)
Equivalent industrial hydraulic fluids
Using clean and proper oil will extend pump life. Contact us if you need oil recommendations.
The recommended operating speed is 800–1800 rpm. For special applications, we can help you confirm the correct speed range.
Yes, we support OEM and customization, including nameplate, packaging, and specific performance requirements. Send us your drawings or specifications for evaluation.

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.
