35V-25A-1C-22R Vickers Cartridge Kit 81cm³ 172bar

Product Overview

The 35V-25A-1C-22R, 35V-35A-1C-22R, 45V-60A-1B-22R, 45V-42A-1D-22R and 45V-50A-1B-22R models are fixed-displacement industrial vane pump cartridge kits fully interchangeable with genuine Vickers (Danfoss) V series. Featuring a 12-vane intra-vane design, these cartridges deliver volumetric efficiency above 90%, low noise and self-compensating wear characteristics. Every unit undergoes 100% simulated duty-cycle testing to guarantee exact matching of dimensions and performance curves with original Vickers 35V/45V cartridges. The modular design allows rapid field replacement without removing the pump from its mounting, significantly reducing maintenance time and cost.

Key Technical Advantages

1. 12-vane intra-vane design significantly reduces flow pulsation and noise (as low as 62–71 dB(A)) while achieving volumetric efficiency over 90%.
2. Self-compensating wear structure ensures performance does not degrade over time; replacing the cartridge restores new-pump performance.
3. Full interchangeability with genuine Vickers 35V/45V cartridges verified by rigorous testing, enabling rapid field service.
4. 100% simulated duty-cycle testing covering pressure, speed and flow curves guarantees factory performance matching original units and minimizes failures.
5. Modular cartridge design allows flow capacity changes without removing the pump from its mounting, improving maintenance efficiency and system flexibility.

Application Areas

Industrial hydraulic systems, presses, injection molding machines, machine tools, metallurgical equipment, material handling equipment and other applications requiring medium-to-high pressure fixed-displacement vane pumps.

Expert Maintenance Tips

• Depressurize the system and clean the work area thoroughly before replacing the cartridge to prevent contamination.
• When installing a new cartridge, torque bolts to specification and ensure sealing surfaces are clean and undamaged.
• On first start-up, set the system relief valve to the lowest setting, run at low speed under no load for several minutes to purge air, then gradually raise pressure.
• Use anti-wear hydraulic oil with appropriate viscosity and maintain high fluid cleanliness; replace filters regularly.
• Periodically inspect shaft seals and pump body mounting bolts; keep sealing areas clean to extend overall service life.
