3. Core Features of Each Series
3.1 PVQ Series
Characterized by high efficiency and compact design, the PVQ series achieves automatic displacement adjustment based on pressure changes, eliminating excess flow waste and reducing energy consumption by over 25% compared to fixed-displacement pumps. Its inline structure facilitates easy installation and maintenance, making it ideal for precision machine tools and light industrial equipment requiring stable pressure output.
3.2 PVB Series
Built for medium-high pressure and heavy-duty applications, the PVB series features enhanced structural rigidity and wear resistance. The swashplate control mechanism ensures smooth operation under shock loads, while the optional electro-proportional control enables precise flow and pressure regulation. It is widely used in construction machinery, hydraulic presses, and other equipment with rigorous durability requirements.
3.3 PVH Series
As a high-pressure flagship series, the PVH series excels in power density and reliability. The through-shaft drive design allows multi-pump combination to meet complex system needs, while the optimized flow distribution technology minimizes pressure fluctuations. It is suitable for heavy machinery, offshore equipment, and high-pressure test benches operating under extreme conditions.
3.4 PVM Series
Focusing on medium-pressure and low-noise performance, the PVM series (including the upgraded PVMX model) integrates intelligent control and energy-saving technologies. The PVMX model supports two-quadrant operation and energy recovery, converting mechanical energy into electrical energy during deceleration or gravity-assisted movements, achieving up to 80% energy efficiency. Its ultra-low noise level makes it perfect for acoustic-sensitive workshops like CNC shearing and plastic processing facilities.
4. Typical Applications
- PVQ Series: Precision CNC machine tools, injection molding machines, small hydraulic presses, and automated production lines.
- PVB Series: Excavators, loaders, hydraulic punches, and die-casting machines.
- PVH Series: Heavy-duty hydraulic systems, offshore oil drilling equipment, high-pressure hydraulic stations, and mining machinery.
- PVM Series: CNC shearing machines, bending machines, servo hydraulic systems, and precision forming equipment. The PVMX model is particularly suitable for energy-saving injection molding and die-casting applications.
5. Safety & Maintenance Notes
- Strictly operate within the specified pressure and speed limits for each series to prevent component damage and safety hazards.
- Before installation and maintenance, shut down the power supply and depressurize the hydraulic system to avoid accidental startup.
- Use hydraulic oil that meets ISO/Vickers standards (viscosity 46-70 cSt at 40ºC for axial piston pumps) and maintain oil cleanliness. Replace oil and filters regularly per maintenance schedules.
- Keep the pump nameplate clean and legible; do not strike or damage aluminum nameplates to avoid spark risks in explosive environments.
- Use only original Vickers spare parts for replacement to ensure consistent performance and compliance with safety certifications.
6. Certification & Compliance
All four series comply with ISO and SAE interface standards for seamless system integration. They meet the requirements of ATEX Directive 2014/34/EU and UKEX SI 2016 No. 1107, with explosion-proof marking Ex II 3G Ex h IIC T3/T4 Gc X for hazardous gas environments. The PVMX model additionally adheres to international energy efficiency directives, supporting low-carbon production goals.
