We eliminate defective products from the source to ensure that every pump delivered to customers has consistent and reliable performance. Compared with similar products on the market, our VVP20Z/20 vane pump has more stable efficiency, lower operating noise and stronger wear resistance, which can effectively reduce equipment failure rate and later maintenance costs for global industrial users.

Core Product Competitive Advantages

1. Reinforced Integral Structure, Strong Impact Resistance

The VVP20Z/20 vane pump adopts an integrally cast high-strength cast iron pump body with high overall rigidity and structural stability. It can effectively resist hydraulic impact, mechanical vibration and external pressure generated during long-term high-speed operation, and will not deform or crack under frequent start-stop and variable load working conditions. The internal stator ring, rotor and vanes are made of high-hardness alloy materials through professional vacuum heat treatment and precision grinding process, with excellent wear resistance and fatigue resistance. The sturdy overall structure enables the pump to adapt to harsh industrial working environments and maintain stable performance for a long time.

2. High Volumetric Efficiency, Stable Energy-Saving Output

Optimized with precision internal gap matching technology, the VVP20Z/20 effectively suppresses internal oil leakage and pressure loss. Its volumetric efficiency remains above 92% during long-term continuous operation, far exceeding the efficiency standard of ordinary ordinary vane pumps of the same specification. Even under long-term full-load operation, it will not produce obvious efficiency attenuation and pressure drop. While ensuring stable and continuous hydraulic power supply for industrial equipment, it reduces invalid energy consumption of the hydraulic system, realizing energy-saving, high-efficiency and low-consumption operation of mechanical equipment.

3. Optimized Flow Channel Design, Ultra-Low Noise Operation

Aiming at the common noise problem of traditional vane pumps, the VVP20Z/20 optimizes the internal oil flow channel and vane engagement angle. The oil suction and pressure discharge process is gentle and continuous, avoiding instantaneous pressure impact and flow pulsation. The overall operating noise is stably controlled below 69dB during high-speed operation, with low vibration and smooth operation. It fully meets the environmental protection and low-noise operation requirements of modern industrial workshops, and will not affect the working accuracy of precision supporting equipment.

4. Simple Structure & Ultra-Low Maintenance Cost

The VVP20Z/20 vane pump features a simple and mature mechanical structure without complex electronic control parts, with low failure rate and high operational stability. All internal vulnerable parts such as vanes, seals and bearings are standardized universal accessories, which are easy to purchase and replace. The modular assembly structure enables quick disassembly and assembly, greatly simplifying daily maintenance and overhaul work. Customers do not need to invest high manpower and material costs in later maintenance, effectively reducing the overall operating cost of hydraulic equipment.

The model specification of VVP20Z/20 follows international general industrial hydraulic pump coding standards, and each code corresponds to independent structural characteristics, displacement parameters and performance configuration, helping customers quickly verify product matching applicability:

Product Structure & Working Principle

The VVP20Z/20 High Performance Low Noise Vane Pump adopts a mature single-stage double-acting vane pump structure, composed of high-strength cast iron pump body, precision rotor assembly, curved sliding vanes, wear-resistant stator ring, floating pressure balance plate and high-performance sealing components. The overall structure is compact, rigorous and easy to install, with high assembly precision and long-term operational stability:

1. Precision Rotor & Vane Core Assembly: The high-precision forged rotor cooperates with optimized curved vanes, which can slide flexibly and fit closely with the stator ring during operation. It realizes continuous and stable oil suction and discharge circulation, effectively reducing mechanical friction and flow pulsation, ensuring stable and uniform flow output.

2. Floating Pressure Balance System: The built-in floating balance plate can automatically adjust the internal fitting gap according to system pressure changes, dynamically compensate component wear gaps, and always maintain the best sealing state. It effectively suppresses internal leakage and avoids performance degradation caused by long-term component wear.

3. Reinforced Pressure-Resistant Pump Body: The integral cast iron pump body has good vibration damping, pressure resistance and structural toughness. It can withstand long-term hydraulic pressure impact and mechanical vibration without deformation, ensuring the overall structural stability of the pump body in complex working environments.

4. High-Performance Sealing Protection Structure: Adopting imported oil-resistant, high-temperature resistant and corrosion-resistant sealing materials, with multi-channel sealing protection at the shaft end and fitting gaps. It effectively prevents hydraulic oil leakage and external dust and impurity infiltration, protecting internal core components and prolonging the overall service life of the pump.
