Vickers (now a brand under Eaton Corporation) is a well-known manufacturer of hydraulic components, and its gear pumps are widely applied in machine tool lubrication systems due to their stable oil supply, low noise, high volume efficiency and strong adaptability. The gear pump series suitable for machine tool lubrication mainly include the GPY series, 35V series, 25V series and V10 series, which can meet the lubrication needs of different types of machine tools (such as CNC machine tools, ordinary lathes, milling machines and grinding machines). The specific series, models and characteristics are as follows:

1. GPY Series (External Gear Pumps for Precision Lubrication)

The GPY series is a high-precision external gear pump specially developed for machine tool lubrication systems. It is characterized by compact structure, low noise (operation noise ≤ 55dB) and stable oil output, which can provide continuous and uniform lubrication oil for machine tool guide rails, bearings and gears. It is especially suitable for precision CNC machine tools and automatic processing equipment that require low-noise and high-stability lubrication.

Core Models:

• GPY-3R: Displacement 3 mL/r, rated pressure 100 bar, suitable for small precision machine tools (e.g., small CNC lathes, engraving machines)
• GPY-4R: Displacement 4 mL/r, rated pressure 100 bar, suitable for medium-sized precision machine tools (e.g., ordinary lathes, drilling machines)
• GPY-6R: Displacement 6 mL/r, rated pressure 120 bar, suitable for large precision machine tools (e.g., CNC milling machines, grinding machines)
• GPY-10R: Displacement 10 mL/r, rated pressure 120 bar, suitable for heavy-duty machine tools with large lubrication demand (e.g., gantry milling machines)

2. 35V Series (Vane Gear Pumps for Medium-Load Lubrication)

The 35V series is a vane-type gear pump integrated with gear transmission and vane pressure regulation, which is widely used in the lubrication system of medium-load machine tools. It has the advantages of adjustable oil output, strong anti-interference ability and long service life, and can adapt to the intermittent lubrication needs of machine tools under different working conditions. Its oil viscosity adaptation range is 30-2500cSt, covering most machine tool lubrication scenarios.

Core Models:

• 35V-25A: Displacement 25 mL/r, rated pressure 160 bar, suitable for medium-load lathes and milling machines
• 35V-35A: Displacement 35 mL/r, rated pressure 160 bar, suitable for heavy-duty boring machines and planers
• 35V-45A: Displacement 45 mL/r, rated pressure 200 bar, suitable for large-scale machining centers and gantry machines

3. 25V Series (Lightweight Gear Pumps for Auxiliary Lubrication)

The 25V series is a lightweight and miniaturized gear pump designed for the auxiliary lubrication circuits of machine tools (such as lubrication of electrical control components and auxiliary mechanisms). It has the advantages of small volume, light weight and easy installation, and can provide stable low-pressure lubrication for auxiliary parts of machine tools, ensuring the normal operation of the whole machine.

Core Models:

• 25V-10A: Displacement 10 mL/r, rated pressure 100 bar, suitable for auxiliary lubrication of small machine tools
• 25V-15A: Displacement 15 mL/r, rated pressure 100 bar, suitable for auxiliary lubrication of medium-sized machine tools
• 25V-20A: Displacement 20 mL/r, rated pressure 120 bar, suitable for auxiliary lubrication of large machine tools and machining centers

4. V10 Series (High-Pressure Gear Pumps for Heavy-Duty Machine Tool Lubrication)

The V10 series is a high-pressure gear pump suitable for the lubrication system of heavy-duty machine tools (such as forging machines, heavy-duty lathes). It has strong wear resistance and high pressure resistance, can adapt to harsh working environments such as high load and high temperature, and provides sufficient lubrication oil for key components of heavy-duty machine tools to prevent wear and damage.

Core Models:

• V10-1P: Displacement 10 mL/r, rated pressure 250 bar, suitable for heavy-duty lathes and forging machines
• V10-2P: Displacement 20 mL/r, rated pressure 250 bar, suitable for large-scale heavy-duty machining equipment
• V10-3P: Displacement 30 mL/r, rated pressure 315 bar, suitable for ultra-heavy-duty machine tools with high lubrication pressure requirements

Note: The specific models and parameters of Vickers gear pumps for machine tool lubrication systems may vary according to the machine tool type, lubrication circuit design and working conditions. For accurate model selection, it is recommended to refer to the official technical manual or consult Eaton Vickers authorized suppliers. In addition, the working temperature range of these gear pumps is generally -10℃ to +70℃, which is compatible with most industrial machine tool working environments.
