PVL12 Double Vane Oil Pump – Product Introduction
The PVL12 is a double fixed-displacement vane pump that provides dual-circuit pressure oil supply for hydraulic systems, supporting multi-circuit hydraulic control. It is widely used in injection molding machines, machine tools, construction machinery and other equipment. Featuring low noise, high pressure resistance and easy maintenance, it is a common power component in industrial hydraulic systems.

3. Core Advantages
· Low Noise & High Pressure: The stator uses a high-order impact-free transition curve for low flow ripple and low noise. Arc-shaped vanes reduce compressive stress on the stator inner curve, extending service life under high pressure.
· High Efficiency & Energy Saving: Hydraulically balanced side plate structure ensures high volumetric efficiency, reducing energy loss and improving system energy efficiency.
· Easy Maintenance: Cartridge-style pump core assembly can be replaced in minutes with good interchangeability, lowering maintenance costs.
· Strong Adaptability: Displacement covers 6–153 mL/r with flexible dual-pump combinations, meeting diverse flow and pressure requirements of hydraulic systems.
4. Application Scenarios
· Injection Molding & Hydraulic Presses: Dual-circuit control for mold clamping/ ejection, slide/table movement.
· Construction Machinery: Multi-valve control for steering, boom, slewing and other multi-actuator systems.
· Machine Tools: Dual-circuit hydraulic systems for hydraulic chucks, turrets, table feeding, etc.
· Die-Casting & Forging Equipment: Synchronous actuation of main/auxiliary cylinders to improve production efficiency.
