The VELJAN cartridge is a hydraulic vane or gear pump unit designed to provide uniform flow and stable pressure in industrial hydraulic systems. Typical operating pressure ranges from 70 to 250 bar, with flow rate depending on size from 10 to 150 liters per minute. Rotor and vanes or gears are made of alloy steel with precise heat treatment to ensure high resistance to wear and fatigue. Precision machining tolerances minimize internal leakage and ensure volumetric efficiency above 88%. This cartridge is suitable for heavy machinery, production lines, and automotive hydraulic systems.
Structurally, the VELJAN cartridge consists of a central rotor, vanes or gears, cam ring, return springs, and side plates. The vanes self-adjust to maintain uniform contact with the cam ring, reducing flow pulsation. Seals are made of NBR or Viton, resistant to heat and oil. The cartridge is mounted directly into the VELJAN pump housing. Operating temperature ranges from -20 to 120°C, with a service life exceeding 10,000 hours. It is optimized for continuous heavy-duty applications.You can order and buy VELJAN from Iran by contacting us through whatsaap and email.

Comparison of Waljan Cartridges with Other Hydraulic Brands
Waljan cartridges provide high-precision manufacturing, up to 350 bar pressure tolerance, and over 93 percent volumetric efficiency, ensuring reliable industrial performance. Compared to standard brands, they exhibit lower internal leakage, faster response, and longer service life. Their modular design allows easy replacement without full system shutdown, and compatibility with standard hydraulic valves and blocks offers high flexibility. Corrosion resistance and operation up to 90°C reduce the risk of sudden failures. Compared to similar brands, Waljan cartridges deliver lower en
