Product Description

Product Overview:

The 25V12A-1A22R, 20V5A-1A22R, 25V17A-1C22R, 25VQ21A1C20 and related 20V/25V/35V/45V/VQ series are classic Eaton Vickers fixed-displacement industrial and mobile vane pumps featuring the proven Intravane design. These units are engineered as drop-in interchangeable replacements that match original mounting flanges, shaft ends, port locations and overall dimensions exactly. 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 mobile applications.

Technical Specifications 

  • Model: 25V12A-1A22R / 20V5A-1A22R / 25V17A-1C22R / 25VQ21A1C20 (20V/25V/35V/45V/VQ series variants)

  • Rated flow (1200 rpm, 7 bar / 100 psi): approx. 5 US gpm (20V5); 12 US gpm (25V12); 17 US gpm (25V17); 21 US gpm (25VQ21)
  • Continuous rated pressure: 172 bar (2500 psi) for 25V series; up to 207 bar (3000 psi) for certain 20V models
  • Peak pressure: up to approx. 207–210 bar (intermittent, fluid-dependent)
  • Maximum speed: 1800 rpm (industrial V series); up to 2500–2700 rpm (mobile VQ series)
  • Minimum speed: approx. 600 rpm
  • Control type: fixed displacement
  • Rotation: clockwise (R, viewed from shaft end) or counterclockwise options
  • Shaft: standard straight keyed (code 1)
  • Ports: SAE 4-bolt flange (code A)
  • Outlet position: A = opposite inlet; C = inline with inlet (and other orientations available)
  • Mounting: flange mount
  • Approximate weight: 12–15 kg (25V single pump)
  • Seals: standard Buna-N or optional Viton

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% even under continuous high-pressure duty.
  3. Low-noise, low-pulsation performance: Twelve-vane configuration minimizes flow ripple; typical sound levels are in the 62–67 dB(A) range at 138 bar and 1200–1800 rpm, suitable for noise-sensitive industrial and mobile 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, plastic processing machinery, metallurgical equipment, mobile construction machinery auxiliary circuits, industrial hydraulic stations and any fixed or mobile installation requiring stable medium-to-high pressure flow.

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.
