Product Description
Atos Type PFE & PFED Series High-Performance Hydraulic Vane Pumps
Product Overview: The PFE and PFED Series represent the pinnacle of “Ultra-High Pressure and Superior Reliability” in the industrial hydraulic sector. Featuring a specialized Cartridge Design, these pumps are engineered for heavy industrial environments requiring continuous high-pressure operation and strict noise control. This range features premium specifications including single models PFE-41056, PFE-41070, and PFE-41085, as well as high-performance double pumps PFED-41056/1DT and PFE-42856/3DT. Utilizing a unique pressure-balanced construction, the PFE series maintains peak volumetric efficiency at pressures up to 30 MPa—serving as the definitive power core for automated heavy-duty equipment.
Key Technical Advantages:
Ultra-High Pressure Capacity: Utilizing reinforced intra-vane structures, these pumps handle rated pressures of 21 MPa and peak pressures up to 30 MPa, far exceeding standard industrial vane pumps.
Modular Cartridge Technology: The internal cartridge functions as an independent unit, allowing for rapid replacement without disconnecting pump plumbing, drastically reducing maintenance costs and downtime.
Ultimate Silent Operation: Precision-ground cam rings and optimized silencing channels ensure exceptionally low noise levels even at extreme pressures, enhancing workshop environments.
Flexible Double Pump Synergy (PFED): Drives two independent displacement cartridges on a single shaft, enabling precise high-low pressure circuit matching for optimized energy efficiency.
Target Applications: Ceramic brick presses, large-scale injection molding machines, hydraulic balers, scrap metal shears, and metallurgical power units.
