Product manual of Vickers vane pump V10/V20 series
1. Introduction
1.1 Product Overview
The Vickers V10 and V20 series are high-performance fixed displacement balanced vane pumps, specifically engineered to cater to the diverse needs of modern mobile and industrial hydraulic systems. With a compact and robust design, these pumps deliver exceptional efficiency, reliability, and long service life, making them ideal for applications such as machine tools, construction equipment, agricultural machinery, and industrial hydraulic circuits. The series is available in both single and double pump configurations, providing flexible solutions for various flow and pressure requirements.
A key design feature of the V10/V20 series is the diametrically opposed internal inlet and outlet pressure chambers, which effectively balance pressure-induced radial loads. This balance significantly reduces bearing stress, minimizes wear, and extends the overall service life of the pump, even under continuous operation in harsh working environments.
1.2 Scope of Application
-
Industrial machinery: Machine tools, hydraulic presses, plastic injection molding machines, and conveyor systems.
-
Mobile equipment: Construction machinery, agricultural tractors, forklifts, and utility vehicles.
-
Other applications: Hydraulic power units, test benches, and any system requiring a reliable, compact fixed displacement pump.
1.3 Safety Precautions
-
Before installation, operation, or maintenance, ensure that all personnel involved have read and understood this manual thoroughly.
-
Always shut off the power supply and relieve system pressure before performing any maintenance or disassembly work to avoid personal injury or equipment damage.
-
Do not operate the pump beyond the specified maximum pressure, speed, or temperature limits, as this may lead to pump failure, oil leakage, or fire hazards.
-
Use only recommended hydraulic fluids and maintain proper fluid cleanliness to prevent internal component wear and blockages.
-
Wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and protective clothing, when working with the pump or hydraulic system.
2. Technical Specifications

3. Installation Instructions
3.1 Installation Preparation
-
Inspect the pump for any damage or missing components before installation. Check the packaging for signs of transit damage and verify that all parts are intact.
-
Ensure the installation location is clean, dry, and well-ventilated, with sufficient space for maintenance and access to the pump’s ports and mounting points.
-
Prepare the mounting surface: It should be flat, smooth, and able to support the pump’s weight and operating vibrations. Clean the surface to remove any dirt, grease, or debris.
-
Select appropriate mounting hardware (bolts, washers) that match the pump’s mounting holes and can withstand the operating loads. Use lock washers or thread locker to prevent bolt loosening due to vibration.
3.2 Mounting the Pump
-
Position the pump on the mounting surface, aligning the mounting holes with the holes on the surface. Ensure the pump is level and properly aligned with the drive shaft (if connected to a motor).
-
Insert the mounting bolts through the pump’s mounting holes and tighten them evenly to the recommended torque (refer to the torque specifications provided in the appendix).
-
If the pump is connected to a motor, ensure the drive shaft alignment is correct (maximum misalignment: 0.1 mm radial, 0.05 mm axial). Use a flexible coupling to reduce vibration transfer and compensate for minor misalignment.
-
Connect the inlet and outlet hoses/pipes to the pump’s ports. Ensure the connections are tight to prevent oil leakage. Use appropriate fittings that match the port size (refer to the model specifications for port dimensions).
3.3 Post-Installation Check
-
Verify that all connections are secure and there are no loose components.
-
Fill the hydraulic system with the recommended hydraulic fluid, ensuring the fluid level is within the specified range.
-
Prime the pump by manually turning the drive shaft (if possible) to ensure the pump is filled with fluid and air is purged from the system.
-
Check for any oil leaks before starting the pump. Tighten any loose connections if leaks are detected.
4. Operation Guidelines
4.1 Startup Procedure
-
Ensure the power supply is connected and the hydraulic system is properly filled with fluid.
-
Turn on the power and start the pump at low speed (approximately 500-600 rpm) to allow the fluid to circulate and the pump to warm up.
-
Monitor the pump’s operation for any unusual noise, vibration, or overheating. Normal operation should be quiet and smooth, with no excessive vibration.
-
Gradually increase the speed to the operating speed and check the system pressure. Ensure the pressure does not exceed the pump’s maximum rated pressure.
-
Verify that the fluid temperature remains within the recommended range (-12°C to 82°C). If the temperature exceeds 82°C, check the cooling system and ensure proper fluid flow.
4.2 Normal Operation
-
Operate the pump within the specified pressure and speed limits at all times. Avoid prolonged operation at or near the maximum rated pressure, as this may reduce service life.
-
Regularly monitor the fluid level and condition. Check for fluid contamination (e.g., dirt, water) and replace the fluid if necessary.
-
Inspect the pump for oil leaks during operation. Address any leaks immediately to prevent fluid loss and potential system damage.
-
Do not shut down the pump abruptly while it is operating at high pressure. Gradually reduce the pressure and speed before shutting off the power.
4.3 Shutdown Procedure
-
Reduce the pump’s speed to low (500-600 rpm) and relieve the system pressure.
-
Turn off the power supply to stop the pump.
-
If the pump will not be used for an extended period (more than 30 days), drain the hydraulic fluid and store the pump in a clean, dry environment. Protect the ports with caps or plugs to prevent contamination.

5.3 Disassembly and Reassembly
Disassembly and reassembly should only be performed by qualified personnel with proper tools and knowledge. Follow these general steps:
-
Shut off the power supply and relieve system pressure. Disconnect the inlet and outlet hoses/pipes and the drive shaft coupling.
-
Remove the mounting bolts and lift the pump from the mounting surface.
-
Disassemble the pump in the following order: end cover, vanes, rotor, cam ring, and bearing assembly. Use proper tools to avoid damaging components.
-
Clean all components thoroughly with a suitable cleaning agent. Inspect each component for wear, damage, or deformation. Replace any worn or damaged parts with genuine Vickers replacement parts.
-
Reassemble the pump in the reverse order of disassembly. Ensure all components are properly aligned and seated. Apply a thin layer of hydraulic fluid to the vanes, rotor, and cam ring before assembly.
-
Reinstall the pump on the mounting surface, reconnect the hoses/pipes and drive shaft coupling, and perform the post-installation check before restarting.
6. Storage and Handling
-
Store the pump in a clean, dry, and well-ventilated area, away from direct sunlight, extreme temperatures, and corrosive substances.
-
Keep the pump in its original packaging until installation to prevent damage and contamination.
-
If the pump is stored for more than 30 days, fill it with a preservative fluid (or the recommended hydraulic fluid) to prevent internal corrosion. Cap or plug all ports to keep out dirt and moisture.
-
When handling the pump, use proper lifting equipment (if necessary) to avoid injury. Do not drop or strike the pump, as this may damage internal components.
