Core Product Advantages

1. Rugged Integrated Structure & Excellent Wear Resistance

The PVQ2-1X055RA15DLMB vane pump adopts an integral high-strength cast iron pump body, which features high overall rigidity, strong anti-deformation and anti-vibration capabilities, and can effectively resist hydraulic impact and mechanical vibration generated during high-speed operation. The internal core components such as rotors, vanes and cam rings are made of high-hardness alloy materials and processed through professional heat treatment and precision grinding technology. The optimized component matching structure greatly reduces mechanical friction loss, and the wear resistance and fatigue resistance of vulnerable parts are significantly improved. It can operate stably for a long time in continuous industrial working environments, effectively reducing equipment failure frequency and improving overall equipment operation stability.

2. Super High Volumetric Efficiency & Energy-Saving Operation

Equipped with a dynamic floating side plate pressure balance system, the PVQ2-1X055RA15DLMB realizes real-time automatic compensation of internal clearance. It always maintains a tiny and uniform sealing gap under different load pressures, which greatly suppresses internal oil leakage. The stable volumetric efficiency is kept above 93% during long-term operation, avoiding the gradual efficiency decline of ordinary vane pumps after long-time use. Whether in no-load standby or full-load working state, the pump can maintain efficient and stable output, reduce invalid energy consumption of the hydraulic system, and achieve long-term energy-saving and efficient operation of industrial equipment.

3. Optimized Flow Channel Design & Ultra-Low Noise

Aiming at the defect of periodic impact noise of traditional vane pumps during oil suction and discharge, the PVQ2-1X055RA15DLMB optimizes the vane angle and internal flow channel structure. The oil feeding and discharging process is smoother and more continuous, avoiding sudden pressure fluctuation and mechanical impact. The overall operating noise is stably controlled below 70dB, which is far lower than industry standard products of the same specification. It will not produce harsh noise and vibration interference during operation, and is very suitable for indoor production workshops, precision processing equipment and other scenarios requiring low-noise and low-vibration working conditions.

4. Stable Operation & Low Maintenance Cost

The PVQ2-1X055RA15DLMB has a mature and simple mechanical structure without complex electronic control parts, with extremely low failure rate and high operation stability. The output flow and pressure are uniform and stable, which will not cause jitter and displacement deviation of hydraulic actuators. All wearing parts are standardized universal accessories with strong versatility and easy replacement. Customers do not need to invest a lot of manpower and material resources in daily maintenance and parts replacement. It realizes low-cost and trouble-free long-term operation of hydraulic equipment, and greatly reduces the later operation and maintenance cost of industrial production lines.
