20V12A Vickers Hydraulic Vane Pump 40 ml/r 210 bar

Product Overview

The Vickers (now Danfoss Power Solutions) V Series is the industry benchmark for industrial hydraulic vane pumps, renowned for low noise, high pressure, long service life, and proven reliability. The V Series encompasses four sub-series—20V, 25V, 35V, and 45V—available in single, double, and thru-drive configurations. Displacement ranges from 7.5 to 193 ml/r, with continuous operating pressure up to 210 bar (3000 psi) and peak pressure up to 280 bar.

The V Series features a 12-vane design with a balanced-type hydraulic structure, fully balancing radial hydraulic forces for long bearing life and smooth operation. The V/VQ Series intra-vane design is the workhorse in industrial applications, with noise ratings as low as 62 dB(A), making it the ideal pump for the confined spaces of the industrial workplace. These pumps offer high volumetric efficiencies exceeding 90% and time-proven reliability.

Our products are manufactured to be 100% interchangeable with Vickers/Danfoss original specifications—a true “drop-in” replacement solution. Every unit undergoes 100% full-load and flow-matching testing under simulated operating conditions before shipment, ensuring volumetric efficiency, flow rate, and noise performance meet or exceed original specifications at rated pressure.

Key Technical Advantages

1. 12-Vane Low-Noise Design
The V Series features a 12-vane system with noise ratings as low as 62 dB(A), making it the ideal pump for the confined spaces of the industrial workplace. The multi-vane design effectively reduces pressure ripple and fluid-borne noise, delivering smooth acoustic quality—particularly suitable for precision manufacturing facilities with strict noise limitations.

2. Balanced-Type Design for Extended Bearing Life
The V Series employs a balanced-type hydraulic design, fully balancing radial hydraulic forces and eliminating radial loads on the rotor. This dramatically reduces bearing stress, significantly extending bearing life and ensuring long-term stable operation under high-pressure conditions.

3. High Volumetric Efficiency & Energy Savings
V Series pumps deliver over 90% volumetric efficiency. Precision-ground internal components minimize internal leakage, reduce heat generation, and maximize overall energy conversion efficiency. The intra-vane design further optimizes sealing performance.

4. Modular Cartridge Design for Rapid Maintenance
The V Series features cartridge-type construction, allowing individual pump cartridges (cam ring, rotor, vanes, plates) to be replaced quickly and independently. On-site repairs or displacement changes can be completed in minutes without removing the entire pump from the system—dramatically reducing downtime.

5. Through-Drive Capability
The V Series supports through-drive capability for series pump connections. A single power source can drive multiple hydraulic pumps, greatly simplifying complex hydraulic system design. Tandem pump combinations include 2520V, 3520V, 3525V, 4520V, 4525V, and 4535V.

6. 100% Drop-In Interchangeability – Zero Retrofit Cost
Manufactured to exact Vickers/Danfoss original specifications—mounting dimensions, port locations, and shaft configurations are identical to the original. Fully compliant with SAE J744 and ISO 3019-1 standards. No piping modifications or installation adapters are required for direct replacement.

Expert Maintenance Tips

1. Model Identification and Selection

• 20V Series: Small housing, displacement 7.5–45 ml/r, suitable for small-to-medium flow requirements

• 25V Series: Medium housing, displacement 17–67 ml/r, industrial standard

• 35V Series: Large housing, displacement 67–121 ml/r, suitable for large hydraulic stations

• 45V Series: Extra-large housing, displacement 138–193 ml/r, suitable for heavy industrial equipment

• Model Naming Convention: Taking 25V21A-1C22R as an example—25V=Series, 21=Displacement code, A=Keyed shaft, 1=Standard shaft, C=Flange mount, 22=SAE 4-bolt flange port, R=Clockwise rotation

2. Installation Precautions

• Verify pump rotation direction matches system requirements—R denotes clockwise, L denotes counter-clockwise (viewed from shaft end).

• 20V Series uses SAE A mounting flange; 25V/35V/45V Series use SAE B or C 2-bolt flanges.

• Suction piping should be as short as possible, minimizing unnecessary restrictions such as elbows.

• The pump housing must not bear piping loads; suction and discharge lines must have independent supports.

3. Pre-Startup Checklist

• Verify oil level in the reservoir is adequate and fluid type is correct (ISO VG32, VG46, or VG68 anti-wear hydraulic oil recommended).

• Confirm all piping connections are secure with no leakage.

• Prime the pump by filling the housing with oil before first startup to prevent dry running.

4. Fluid Management

• High-quality anti-wear hydraulic oil is recommended; maintain fluid cleanliness at NAS 9 or higher—contamination is the leading cause of premature vane pump failure.

• Regularly check oil temperature to ensure it does not exceed 60°C.

• V Series is compatible with anti-wear hydraulic oil, water glycol, and phosphate ester fluids.

5. Scheduled Maintenance

• Replace hydraulic oil and filters every 2000 operating hours or annually.

• The V Series features cartridge-type construction—cartridges can be replaced independently without removing the entire pump.

• If flow drops or pressure becomes unstable, first inspect cartridge wear—replacing the cartridge kit restores performance.
