Product Description

Product Overview

The V20-1B13B-1A11-EN1000 and V20-1B11B-1A11-EN1000 are single-stage, balanced vane, fixed displacement hydraulic pumps from the Eaton/Vickers V20 series — one of the most widely installed industrial vane pump platforms globally. Built to the proven 22nd-generation design standard (EN1000), these pumps feature Vickers’ patented intra-vane construction with a 12-vane system that delivers continuous operating pressures up to 207 bar (3000 psi), volumetric efficiency exceeding 90%, and noise levels as low as 62 dB(A).
Engineered for drop-in interchangeability, these pumps maintain full dimensional compatibility with original Vickers specifications — mounting flange, shaft extension, and port positions are identical to the OEM units they replace. Every pump is 100% factory tested under simulated working conditions, including pressure-flow curve verification, ensuring immediate performance parity upon installation. The modular cartridge kit design allows complete pump core replacement without removing the pump body from the machine, minimizing downtime and maintenance costs.

Key Technical Advantages

1. Patented Intra-Vane Construction
The V20 series employs Vickers’ proprietary intra-vane mechanism — a secondary (sub-) vane is nested within the primary (master) vane, with pressurized oil channeled directly to the sub-vane cavity. This design precisely regulates the contact force between the vane tip and the cam ring surface, ensuring reliable sealing at high pressure while preventing excessive impact loading at elevated speeds. The result is significantly extended service life for both the stator ring and vane elements compared to conventional spring-loaded vane designs.
2. 12-Vane System for Ultra-Low Flow Pulsation & Noise
With 12 vanes (a multiple of 4), the V20 pump minimizes instantaneous flow pulsation amplitude to the lowest achievable level. This translates to exceptionally smooth hydraulic output and system noise characteristics as low as 62 dB(A) — making it ideal for noise-sensitive indoor industrial environments such as precision injection molding facilities, electronics assembly lines, and medical equipment manufacturing.
3. Hydraulic Balance Eliminates Radial Bearing Loads
As a balanced (double-acting) vane pump, the V20 features two suction zones and two discharge zones arranged in radial symmetry. The inlet and outlet pressure chambers are positioned diametrically opposite, ensuring that all pressure-induced radial forces on the rotor are completely canceled. Bearings are subjected only to external loads (e.g., coupling forces), not hydraulic radial loads. This fundamental design principle is the primary engineering driver behind the V20 series’ industry-leading bearing life and reliability.
4. Modular Cartridge Kit for Rapid Field Service
The complete working assembly — rotor, cam ring, vanes, and distributor plate — is integrated into a single removable cartridge kit. Field maintenance requires only end cover removal to extract and replace the cartridge; the pump body remains mounted on the machine. Factory-tested cartridge kits restore new-pump performance upon installation, reducing maintenance time from hours to minutes and dramatically cutting downtime costs.
5. High Volumetric Efficiency Across Wide Operating Envelope
Precision-controlled axial clearances and a high-order, non-impact transition curve machined into the cam ring’s inner surface ensure volumetric efficiency consistently above 90% at 207 bar working pressure. The optimized inlet flow path provides uniform fluid acceleration, enabling excellent self-priming characteristics even at high speeds and low inlet pressures — critical for reliable operation in demanding industrial cycles.

Application Areas

  • Injection Molding Machines: 50–150 ton machines for clamp, ejector, core-pull, and injection circuits requiring precise flow control and stable high-pressure output
  • Hydraulic Presses & Die Casting Machines: Main drive circuits for stamping, bending, and die casting operations subject to cyclic shock loading
  • Industrial Power Units (HPU): Central hydraulic power sources serving multiple actuator circuits in manufacturing plants
  • Material Handling Equipment: Forklifts, scissor lifts, conveyor drives, and palletizing systems
  • Machine Tool Hydraulics: Clamping, feed, and tool-change circuits on CNC machining centers
  • Mining & Metallurgical Equipment: Hydraulic roof supports, rolling mill screw-down systems, and heavy-duty industrial circuits
  • Marine Deck Machinery: Steering gears, winches, and cargo handling hydraulic systems

Expert Maintenance Tips

  • Fluid Cleanliness Control: Maintain system fluid cleanliness at ISO 4406 19/17/14 or better. Install a 100–150 mesh suction strainer and a 10μm return-line filter. Contaminated fluid is the leading cause of abnormal vane wear and cam ring scoring.
  • Viscosity & Temperature Management: Use ISO VG 32–68 anti-wear hydraulic oil (Denison HF-0/HF-1 compliant). Maintain operating viscosity between 17–55 cSt (approx. 30–65°C oil temperature). For cold starts below 10°C, perform a no-load warm-up cycle to prevent cavitation from high-viscosity fluid.
  • Never Operate Dry: Running the V20 pump without fluid causes instant dry-friction damage to vane tips and the cam ring. After installation or prolonged storage, pre-fill the pump cavity through the case drain port with clean fluid before starting.
  • Shaft Alignment & Coupling Selection: Maintain shaft misalignment within 0.05 mm (radial offset) and 0.5° (angular). Use a flexible coupling (jaw-type or tire-type) to absorb installation errors and axial float. Never use rigid couplings or direct belt/gear drives, as radial side-loads will cause premature bearing failure.
  • Cartridge Replacement Procedure: When replacing the cartridge kit, ensure the distributor plate is correctly located using alignment dowel pins. Verify vane chamfer orientation (do not install vanes in reverse). Confirm the cam ring’s suction and discharge zones are correctly aligned. After assembly, manually rotate the shaft to verify smooth, binding-free operation before energizing the drive.
