1. Product Overview

The Vickers PVM series hydraulic pump, a medium-pressure variable displacement piston pump under Danfoss Power Solutions, serves as the core power unit for CNC shearing machines. Designed with advanced swashplate technology, it integrates high reliability, precise control, and low-noise operation, perfectly adapting to the rigorous working conditions of metal forming equipment such as CNC shearing machines that require frequent start-stop cycles and stable pressure output.

2. Technical Specifications

• Working Pressure: Continuous working pressure up to 280 bar; intermittent peak pressure reachable 320 bar, ensuring sufficient power for the shearing process of thick metal plates.
• Structural Design: Adopts swashplate swing structure, which effectively reduces structural and fluid-borne noise, with the minimum noise level controllable at a low range suitable for acoustic-sensitive workshops.
• Displacement & Speed: Optimized displacement range for CNC shearing machine demands, matching servo motor operation with rated speed adaptable to high-speed response requirements of shearing actions.
• Control Options: Supports multiple control modes including pressure compensation and load sensing, enabling intelligent adjustment of oil flow and pressure according to shearing load, reducing energy consumption by over 30% compared to conventional pumps.

3. Core Features

3.1 High Precision & Stability: The precise swashplate control mechanism ensures stable oil supply pressure and flow, avoiding pressure fluctuations that may affect shearing accuracy. It provides reliable hydraulic power for the positioning and shearing actions of CNC shearing machines, improving processing precision.

3.2 Low Noise Operation: Special structural optimization minimizes both mechanical and fluid noise, creating a quieter working environment, which is particularly suitable for factory workshops with strict noise control requirements.

3.3 Durable Performance: Constructed with high-quality materials and precision machining, it features strong wear resistance and long service life, adapting to the continuous working demands of CNC shearing production lines.

3.4 Easy Integration: Complies with ISO and SAE interface standards, offering various mounting flanges and shaft configurations for seamless integration with different models of Vickers CNC shearing machines.

4. Application in CNC Shearing Machines

As the core power component of CNC shearing machines, the PVM series hydraulic pump is mainly responsible for driving the shearing blade movement, worktable positioning, and clamping mechanism operation. Its fast response speed ensures quick start and stop of shearing actions, while stable pressure output guarantees uniform shearing force, preventing metal plate deformation or shearing failure. It is widely applied in precision metal cutting and forming scenarios of CNC shearing machines, suitable for processing various metal materials such as steel plates and aluminum sheets.

5. Safety & Maintenance Notes

• Strictly operate within the specified maximum working pressure to avoid pump damage or potential safety hazards.
• Before installation and maintenance, ensure the CNC shearing machine is powered off and the hydraulic system is depressurized to prevent accidental startup.
• Use recommended hydraulic oil types and maintain proper oil level and cleanliness; replace hydraulic oil and filters regularly according to maintenance schedules.
• The pump’s nameplate contains critical information such as model, serial number, and certification; keep it clean and legible. Do not strike or damage the aluminum nameplate to avoid spark hazards.
• Only use original Vickers spare parts for replacement to ensure consistent performance and safety compliance.

6. Certification & Compliance

The PVM series hydraulic pump meets the requirements of ATEX Directive 2014/34/EU and UKEX SI 2016 No. 1107, marked as Ex II 3G Ex h IIC T3/T4 Gc X for use in potentially explosive gas environments. It complies with international industrial hydraulic standards, ensuring safe and reliable operation in global CNC shearing machine applications.
