4525V60A17 Vickers Eaton Double Vane Pump 193+55 cm³/r

Product Overview:

The 2520V, 3520V, 3525V, 4520V, 4525V, 4535V series (including 4525V60A17 1CC22L) are classic Eaton Vickers fixed-displacement double vane pumps featuring the proven Intravane design. These units combine two independent cartridges in a single body with a common inlet and two separate outlets, enabling compact high-low pressure or multi-circuit configurations. Manufactured to exact original geometric tolerances, they offer true drop-in interchangeability—matching mounting flanges, shaft ends and port centers precisely—so they can replace OEM units without system modifications. Every pump undergoes 100% simulated duty-cycle testing to verify volumetric efficiency, pressure retention and noise performance. Hydraulic balancing of the vanes combined with precision-machined cam rings and rotors delivers low pulsation, quiet operation and extended service life, making them the preferred choice for injection molding machines, die-casting equipment, machine tools and metallurgical systems.

Key Technical Advantages:

1. True drop-in interchangeability and precision manufacturing: Manufactured to original geometric tolerances so that shaft, pilot, flange and port centers match exactly, enabling direct replacement without system modifications and minimizing downtime.
2. High volumetric efficiency with hydraulically balanced vanes: The Intravane design balances pressure on both sides of each vane, reducing cam-ring wear and delivering volumetric efficiencies typically above 90%, with dual independent outputs for simultaneous high-low pressure or dual-circuit needs.
3. Low-noise, low-pulsation performance: Twelve-vane configuration minimizes flow ripple; low sound levels at 138 bar and 1200–1800 rpm make them suitable for noise-sensitive industrial environments.
4. Long service life and field-replaceable cartridge: Independent cartridge design allows quick on-site replacement of the rotating group; high-quality bearings and wear-resistant materials extend overall pump life and lower total cost of ownership.

Application Areas:

Hydraulic power units for injection molding and die-casting machines, machine tools and machining centers, metallurgical and rolling-mill equipment, plastic processing machinery, industrial hydraulic stations and any fixed installation requiring stable medium-to-high pressure dual-flow output.

Expert Maintenance Tips:

1. Ensure precise shaft alignment during installation (flexible coupling recommended) to avoid additional radial or axial loads that accelerate bearing wear.
2. Fully prime the pump and verify a leak-free, air-free suction line before initial start-up; use clean anti-wear hydraulic oil of NAS 7 or better cleanliness.
3. Maintain suction and return filters regularly to prevent particle ingress that can score vanes and the cam ring; keep operating temperature in the 50–60°C range for optimal life.
4. When replacing the cartridge, maintain cleanliness and tighten housing bolts to original torque values; for long-term storage, run the pump briefly every 3–6 months to prevent internal corrosion.
