Vane Pumps in Stock
Vane pumps are positive-displacement hydraulic pumps that use a set of sliding vanes mounted on a rotor to move fluid through the pump. As the rotor turns inside a cam ring, the vanes extend and retract, creating expanding and contracting chambers that draw fluid in and push it out with smooth, quiet flow. Known for their low noise, compact size, and steady output, vane pumps are widely used in industrial and mobile hydraulic systems that require reliable, mid-pressure performance. Our comprehensive inventory spans fixed and variable displacement vane pump configurations, including single, double, and triple vane pumps.
Hengyuhang combines robust manufacturing capacity with specialized engineering expertise to produce high-performance vane pumps. Manufactured to stringent international quality standards, our vane pumps deliver the reliability, efficiency, and long service life required to serve as direct, drop-in replacements for leading international brands. When standard equipment cannot meet specific technical demands, our facility designs and manufactures entirely custom vane pump solutions — from rapid prototyping to full-scale production — engineered strictly to your operational parameters and application needs.
What Is a Vane Pump?
A vane pump is a positive-displacement pump that moves hydraulic fluid using sliding vanes mounted in a rotor. As the rotor rotates inside an offset cam ring, centrifugal force and hydraulic pressure push the vanes outward against the ring, forming sealed chambers that expand on the suction side and contract on the discharge side. This design produces a smooth, quiet, low-pulsation flow, and vane pumps are especially valued for their compact size, low noise, and ease of maintenance in industrial and mobile hydraulic applications.
Types of Vane Pumps
Vane pumps are available in two main categories based on displacement control.
Fixed displacement vane pumps deliver a constant flow per revolution. They are simple, reliable, and quiet, and are commonly used in power steering, machine tools, and industrial hydraulic power units. Single, double, and triple pump configurations allow multiple circuits to be supplied from one shaft.
Variable displacement vane pumps can adjust their flow output by changing the eccentricity of the cam ring. They deliver only the flow the system requires, reducing heat and saving energy, and are widely used in press, injection molding, and machine tool applications.
Both types are available in single, double, and triple configurations, with a choice of pressure ranges, mounting flanges, and shaft types to match your system.

FAQ of Vane Pumps
1. What is a vane pump used for?
Vane pumps are used to transfer and pressurize hydraulic fluid in machine tools, injection molding machines, industrial presses, power steering systems, and lubrication units where quiet, steady flow is required.
2. What is the difference between fixed and variable displacement vane pumps?
Fixed displacement vane pumps deliver a constant flow per revolution, while variable displacement vane pumps adjust flow output to match system demand, saving energy and reducing heat.
3. What are the advantages of a vane pump?
Vane pumps offer low-noise, low-pulsation operation, compact size, self-compensating vanes for long service life, and simple maintenance.
4. Can your vane pumps replace other brands?
Yes. Our vane pumps are engineered as direct, dimensionally interchangeable replacements for leading international brands such as Rexroth, Denison, Eaton, Vickers, Yuken, and more.
5. Do you offer custom or OEM vane pumps?
Yes. We offer OEM batch customization — you can provide the design, or we can design the pump to your specification, with optional private labeling.
6. What is the MOQ for OEM orders?
MOQ is flexible depending on the model and customization requirements. Contact us for a tailored quotation.
7. What is your lead time?
Lead time depends on quantity and customization. Standard models ship quickly; custom orders are confirmed at quotation.
