PFE-41070 Atos Fixed Vane Pump 69.9 cm³/r 210 bar

Product Overview

The PFE-41070-1DT, PFE-41085-1DT, PFE-42070-1DT, PFE-52090-1DT, PFE-21010-1DT, PFE-21012-1DT and PFE / PFED series are Atos fixed-displacement twelve-vane pumps. These units feature a cartridge design with integral hydraulic balancing for high-pressure operation, long service life and low noise. Manufactured to exact original geometric tolerances, they offer true drop-in interchangeability—matching mounting flanges, shaft ends and port centers precisely—so they can replace OEM units without system modifications. Every pump undergoes 100% simulated duty-cycle testing to verify volumetric efficiency, pressure retention and noise performance. Inlet and outlet ports can be oriented in four positions, and the pumping cartridge is easily replaceable, making them ideal for industrial hydraulic systems.

Key Technical Advantages

1. True drop-in interchangeability and precision machining: Exact match to Atos original mounting dimensions, shaft ends and port centers enables direct OEM replacement without system changes, minimizing downtime and modification costs. High-precision cam ring, rotor and vane processing ensures consistent performance.
2. High volumetric efficiency with hydraulic balancing: Twelve-vane design with integral hydraulic balancing significantly reduces cam-ring wear, delivering high volumetric efficiency and stable flow under high continuous pressure.
3. Low-noise and low-pulsation design: Optimized inlet geometry and vane configuration minimize oil turbulence and flow ripple, resulting in quiet operation (approx. 62–74 dBA) suitable for industrial environments.
4. Long-life bearings and easy maintenance: Quality bearings and wear-resistant materials extend service life; independent replaceable cartridge design allows rapid on-site maintenance, reducing total cost of ownership.

Application Areas

Hydraulic systems for machine tools and machining centers, injection molding and die-casting machines, plastic machinery, metallurgical equipment, industrial hydraulic power units and multiple-pump combinations.

Expert Maintenance Tips

1. Ensure precise shaft alignment during installation (flexible coupling recommended) to avoid additional radial or axial loads that accelerate bearing wear.
2. Fully prime the pump and verify a leak-free, air-free suction line before initial start-up; use clean anti-wear hydraulic oil (DIN 51524) of high cleanliness class.
3. Maintain suction and return filters regularly to prevent particle ingress that can score vanes and the cam ring; keep operating oil temperature within recommended range.
4. When replacing the cartridge, work in a clean environment and tighten housing bolts to original torque values; for long-term storage, run the pump briefly every 3–6 months to prevent internal corrosion.
