Vickers V-Series Vane Pump Specifications
1. Product Overview
As a classic fixed-displacement vane pump series under Danfoss Power Solutions, the Vickers V series is specifically engineered for medium-pressure industrial applications. It pioneers the industry-first intra-vane cartridge design, integrating ultra-low noise performance, high volumetric efficiency, and easy maintenance. Available in single, double, and through-drive configurations, the series covers frame sizes including 20V, 25V, 35V, 45V, and 50V, as well as double-pump models like 2520V, 3525V, and 4535V. This versatility enables it to meet diverse flow and pressure requirements of hydraulic systems, serving a wide range of industrial and mobile equipment fields.

| Single/Through-Drive Pump (35V/35VT) | 81-121 cm³/r (4.9-7.4 in³/r) | 172 bar (2,500 psi) / 190 bar (2,750 psi) | 1,800 rpm | 22.7 kg (50 lbs) | High flow output, ideal for medium-duty applications |
| Single/Through-Drive Pump (45V/45VT) | 138-193 cm³/r (8.4-11.8 in³/r) | 172 bar (2,500 psi) / 190 bar (2,750 psi) | 1,800 rpm | 34.0 kg (75 lbs) | Large displacement, suitable for high-flow hydraulic circuits |
| Double Pump (2525V, 3525V, 4535V, etc.) | 7-193 cm³/r (1.1-11.6 in³/r) (combined displacement) | Up to 207 bar (3,000 psi) (continuous) | 1,800 rpm | Varies by combination | Dual flow output, reduces system complexity |
Note: The displacement of double pumps can be customized by combining different end and cover-end displacement codes, meeting personalized system requirements.
3. Core Features
3.1 Innovative Structural Design
The industry-leading intra-vane cartridge design enhances wear resistance and extends service life, allowing over 10 million pressure cycles under rated continuous pressure. The pressure-balanced modular structure simplifies maintenance—cartridge assemblies can be quickly replaced without disassembling the entire pump, reducing downtime.
3.2 Ultra-Low Noise Performance
Equipped with a 12-vane system, the pump achieves extremely low noise levels, making it the preferred choice for indoor industrial environments with strict noise control requirements (e.g., plastic injection molding workshops). The optimized vane movement and fluid channel design further minimize fluid-borne and mechanical noise.
3.3 High Efficiency & Durability
With a volumetric efficiency exceeding 90%, the V series reduces energy waste and system heat generation. High-quality materials and precision machining ensure stable performance under harsh operating conditions, while the pressure-balanced design reduces internal wear and extends the pump’s service life.
3.4 Versatile Configuration Options
Through-drive models (e.g., 25VT, 35VT) support single-input multi-pump drive, suitable for complex hydraulic systems requiring centralized power supply. Double pumps offer flexible flow matching, eliminating the need for multiple independent pumps and saving installation space.
4. Typical Applications
- Industrial Manufacturing: Plastic injection molding machines, hydraulic presses, material handling equipment, and industrial power units. The high volumetric efficiency and stable pressure output adapt to the cyclic load changes of presses and the continuous operation needs of injection molding machines.
- Mobile Machinery: Earthmoving equipment, aerial booms, and agricultural machinery. Through-drive and double-pump configurations meet the multi-actuator power requirements of mobile equipment, while the durable structure resists shock and vibration.
- Special Equipment: Steam turbine control systems, marine hydraulic systems, and environmental protection equipment. Some models with corrosion-resistant coatings adapt to harsh environments such as sewage treatment and waste incineration, ensuring long-term continuous operation.
5. Safety & Maintenance Notes
- Operate strictly within the specified continuous pressure range to avoid pump damage or safety hazards; do not exceed peak pressure for extended periods.
- Before maintenance, shut down the power supply and depressurize the hydraulic system to prevent accidental startup. Use original Vickers cartridges and spare parts for replacement to ensure performance consistency.
- Use hydraulic oil complying with Vickers standards (viscosity 46-70 cSt at 40ºC) and maintain oil cleanliness. Regularly replace oil and filters according to the maintenance schedule to prevent wear caused by contamination.
- The pump nameplate contains critical information such as model, displacement, and pressure rating; keep it clean and legible. Avoid striking or damaging the nameplate to prevent information loss.
6. Certification & Compliance
The V series vane pumps comply with SAE and ISO interface standards, enabling seamless integration with global hydraulic systems. They meet the reliability and safety requirements of industrial equipment directives, with explosion-proof options available for hazardous gas environments (complying with ATEX Directive 2014/34/EU) to adapt to special working conditions.
