Fixed displacement vane pumps primarily consist of the following components:

• Pump body: Made of high-strength cast iron or aluminum alloy, providing structural support and oil passages.
• Rotor: A precisely machined cylindrical body with radial slots, within which the vanes slide.
• Vanes: Made from wear-resistant materials (such as phenolic resin or alloy steel), they rely on centrifugal force or pressurized oil to maintain close contact with the inner surface of the stator.
• Stator ring: Its inner surface has a specific curve (circular or eccentric profile) that guides the vane movement to form sealed chambers.
• Distribution plate: Controls the oil inlet and outlet paths, ensuring separation between the suction and pressure zones.
• Drive shaft: Connects to the power source (e.g., motor), transmitting torque to drive the rotor's rotation.
• Sealing components: Prevent oil leakage and ensure stable system pressure.

• High efficiency & stability: Optimized vane design reduces internal leakage, with volumetric efficiency reaching 85%~92%.
• Low pulsation & low noise: A multi-vane structure (typically 8-12 vanes) balances pressure fluctuations, resulting in operational noise below 70dB(A).
• Wide adaptability: Can transport mineral oils, synthetic oils, and high water-based hydraulic fluids, with an operating temperature range of -20℃ to +80℃.
• Long lifespan design: Features wear-resistant coated vanes and precision bearings, with an average Mean Time Between Failures (MTBF) exceeding 10,000 hours.
• Flexible installation: Offers various installation methods such as flange-mounted and bracket-mounted, supporting clockwise/counter-clockwise rotation.
