Atos PFE-51 High Performance Vane Pump

The Atos PFE-51 is a high-performance fixed displacement vane pump (Size 3) designed for high-pressure industrial applications. Part of the renowned PFE series, it features a cartridge-style pumping element with integral hydraulic balancing. This design ensures high volumetric efficiency, exceptionally long service life, and low noise levels, even when operating at pressures up to 210 bar.

Key Features:

Series: PFE-51 (Size 3)
Displacement: 90 to 150 cm³/rev
Max. Pressure: 210 bar (3000 psi)
Design: 12-Vane Cartridge Type.

Product Overview The Atos PFE-51 Series represents a significant evolution in vane pump technology. Unlike simpler pumps, the PFE utilizes a cartridge design where the entire pumping mechanism (rotor, vanes, cam ring, and side plates) is contained within a replaceable cartridge. This allows for rapid maintenance and displacement changes without removing the pump body from the system. The 12-vane rotor design reduces pressure pulsations and noise, making it suitable for modern, quiet industrial environments.

Why Choose Atos PFE-51?

High Reliability: Hydraulic balancing of radial loads on the rotor shaft eliminates bearing stress, ensuring extended durability.
Easy Maintenance: The “pump-in-a-pump” cartridge concept simplifies servicing and reduces machine downtime.
Flexibility: The inlet and outlet ports can be oriented in four different positions relative to each other for easy plumbing.
Performance: Excellent suction characteristics and high volumetric efficiency (>90%).

Common Applications:

Die Casting: Injection mechanism hydraulics.
Ceramic Industry: Heavy-duty presses.
Plastic Machinery: Injection Molding Machines.
Recycling: Balers and Compactors.
Steel Industry: Processing lines.
