PFE-32036/3DT Atos Vane Pump 35.6cc 300bar

Product Overview

The PFE-32, PFE-42 and PFE-5 (PFE-52) series are Atos fixed-displacement high-pressure low-noise vane pumps featuring cartridge design with integral hydraulic balancing. They deliver high volumetric efficiency, long service life and quiet operation. Manufactured to original Atos specifications for 100% drop-in interchangeability and fully tested under simulated operating conditions, these pumps serve as direct replacements for genuine Atos PFE units and are widely used in injection molding machines, machine tools and hydraulic power units.

Key Technical Advantages:

1. Cartridge design with integral hydraulic balancing delivers high volumetric efficiency and low noise; the cartridge can be replaced quickly for simplified maintenance.
2. High-pressure capability up to 300 bar combined with precision vanes and balanced plates ensures long service life under demanding industrial conditions.
3. Flexible port orientation (four positions) and SAE standard flanges facilitate system integration and drop-in replacement.
4. Full dimensional, interface and performance interchangeability with original Atos units, backed by 100% simulated duty-cycle testing, ensures consistency, reliability and reduced downtime and maintenance costs.

Application Areas:

Injection molding machine hydraulic systems, machine tool feed and clamping circuits, industrial hydraulic power units, die-casting machines, plastics machinery, material handling equipment and other applications requiring stable high-pressure fixed-displacement vane pumps.

Expert Maintenance Tips:

1. Ensure suction lines are clear with inlet pressure within the recommended range (−0.15 to 1.5 bar) to prevent cavitation; maintain proper flange alignment.
2. Fully fill and bleed the unit before first start-up. Use ISO VG46 mineral oil or compatible fluid; maintain proper oil temperature and filtration (NAS 1638 class 9 or better).
3. Periodically inspect the cartridge for wear; monitor case temperature and noise levels. Avoid prolonged operation above maximum pressure.
4. When replacing, confirm exact displacement code, rotation direction and port positions. The cartridge can be replaced independently. Perform unloaded and loaded test runs after installation to verify proper function.
