Product details

I. Product Overview

The VQ series vane pump cartridge kits are core components in hydraulic systems, suitable for various industrial equipment such as plastic injection molding machines, rubber machinery, foundry machinery, machine tools, shoe-making machinery, and mining machinery. Renowned for their high pressure, low noise, and excellent performance, all components in these kits are interchangeable with original parts, including the pump cartridge, shaft, seals, bearings, etc.

II. Models and Specifications

• Models: 20VQ, 25VQ, 35VQ, 45VQ

• Displacement Range: 7 to 237 milliliters per revolution (ml/r)

• Maximum Operating Pressure: 21 megapascals (MPa)

• Speed Range: 600 to 2,200 revolutions per minute (rpm)

III. Technical Features

1. High-Pressure Design:

• The pump cartridge kits feature an internal vane design, enabling high pressure, large flow rates, compact size, low noise, and long service life.

• With a maximum operating pressure of 21 MPa, they meet the demands of high-load hydraulic systems.

2. High Efficiency:

• Hydraulically balanced design eliminates bearing loads caused by pressure, with bearings only subjected to radial loads from the drive itself, extending service life and reducing maintenance.

• Vane thickness can be increased based on actual outlet pressure requirements without increasing the load between the vanes and the cam ring, ensuring reliability.

3. Wear Resistance:

• Equipped with wear-resistant flexible side plates to further enhance speed and service life.

• Dual vane arrangement ensures stable tracking of the cam ring throughout the pumping cycle, reducing vane tip leakage and improving volumetric efficiency.

4. Easy Maintenance:

• The pump cartridge kits can be replaced on-site without removing the pump from its installation position, reducing downtime and maintenance costs.

• Compliant with ISO/SAE standards, they offer easy installation and reliable performance.

IV. Application Areas

• Industrial Equipment:

• Plastic injection molding machines, rubber machinery, foundry machinery, machine tools, shoe-making machinery, mining machinery, etc.

• Hydraulic Systems:

• Vehicle hydraulic systems, construction machinery, agricultural machinery, etc.
