Product Description

Eaton Vickers 20VQ 25VQ 35VQ 45VQ Hydraulic Pump Cartridge Kits | VQ Series Replacement Parts for Caterpillar Equipment

Our V & VQ Series Hydraulic Cartridge Kits are high-quality replacement parts fully compatible with Eaton Vickers hydraulic vane pumps. All internal components are designed to meet OEM specifications and ensure 100% interchangeability with original Vickers pump parts, including cartridge kits, shafts, bearings, seals, and other hydraulic components.

These hydraulic vane pump cartridge assemblies maintain the same installation dimensions as the original pumps while delivering lower noise levels, higher efficiency, and improved operational reliability.

Our VQ series cartridge kits are widely used as hydraulic spare parts for Caterpillar equipment and other industrial hydraulic systems.

Key Features

High-Performance Hydraulic Vane Pump Design
Engineered for demanding industrial applications such as plastic injection molding machines, shoe machinery, die-casting equipment, and metallurgical systems.

Hydraulically Balanced Intravane Structure
Reduces pressure load on the stator, improving pump efficiency, operational stability, and extending the service life of hydraulic pumps.

Low Noise Operation
The 12-vane rotor system minimizes flow pulsation, ensuring quieter hydraulic systems and smoother performance.

Multiple Displacement Options
Available with different flow capacities and four outlet port configurations to meet various hydraulic system requirements.

Easy Maintenance Cartridge Design
The modular cartridge assembly allows quick replacement without removing the pump housing from the machine, reducing downtime and maintenance costs.
