Atos Type PFE Series Vane Pump | PFE-31, PFE-41, PFE-51 | High Pressure

Atos Type PFE Series High-Pressure Industrial Vane Pumps

Product Overview: The PFE Series fixed displacement vane pump is the premium standard for global heavy-duty industrial hydraulics, renowned for its exceptional high-pressure capability and extended service life. Featuring a unique 12-vane rotor and modular cartridge design, this series is engineered to deliver consistent, stable power in the most grueling environments. This range features a complete spectrum of specifications: from the compact PFE-31010 / 31036, to the medium-displacement PFE-41056, and the heavy-duty PFE-51129. Its integrated symmetrical pressure-balanced structure eliminates radial bearing loads, ensuring ultra-quiet operation and superior volumetric efficiency even during high-pressure cycles up to 21-30 MPa.

Key Technical Advantages:

• Superior High-Pressure Performance: PFE series single pumps can handle continuous pressures up to 21 MPa and peak pressures up to 30 MPa, significantly outperforming conventional vane pumps.

• Modular Cartridge Design: The internal core (cartridge) acts as an independent module. Maintenance is streamlined—swap the cartridge kit on-site without disconnecting plumbing, drastically reducing downtime.

• Ultimate Silent Operation: The 12-vane design combined with precision-ground port plates suppresses flow pulsations, maintaining decibel levels far below industry standards for automation-friendly workshops.

• Excellent Contamination Resistance: Hardened working components offer superior tolerance to fine particles in hydraulic fluids, ensuring a much longer service life compared to standard pumps.

• Target Applications: Industrial presses, scrap metal balers, large injection molding machines, ceramic presses, and various heavy-duty hydraulic power systems.
