Vickers Type 25V Vane Pump | 25V17A-1A22R, 25V21A-20, 25V14A | Low Noise

Vickers Type 25V Series High-Performance Low Noise Vane Pumps

Product Overview: The 25V Series fixed displacement vane pump is a legendary power solution in the industrial hydraulic sector, renowned for its reliability and silent operation. Engineered for extended service life and ultra-low pulsation, it features the patented Intra-vane design. This selection highlights premium models: 25V17A-1A22R, 25V21A-20, and 25V14A-11C22R. Utilizing precision-machined port plates and a hydraulically balanced structure, the 25V series maintains exceptional volumetric efficiency and significantly reduces factory noise levels even at continuous pressures up to 17.2 MPa (172 Bar).

Key Technical Advantages:

• Intra-vane Technology: The unique vane structure reduces vane-tip loading against the stator, ensuring stable output and significantly extending the pump’s service life under high-pressure cycles.

• Superior Noise Suppression: Acoustically optimized housing effectively dampens flow pulsations, making it the preferred choice for indoor factory environments like injection molding shops.

• Modular “Drop-in” Cartridge Maintenance: The internal components are housed in a modular cartridge. Maintenance is streamlined—swap the internal core on-site in minutes without disconnecting heavy plumbing from the machine.

• High Interchangeability: Mounting dimensions fully comply with industrial standards, providing a perfect direct replacement for original Vickers units and reducing overall spare parts costs.

• Target Applications: Plastic molding machines, metal cutting tools, automated presses, material handling equipment, and diverse industrial Hydraulic Power Units (HPU).
