PFED-43045/016 Atos Double Vane Pump | 210 Bar

Product Overview:

Engineered for heavy-duty industrial systems requiring independent multi-circuit fluid power, the PFED-43045/016/1D double vane pump (covering various combinations like PFED-43029/022) combines two high-performance pump cartridges into a single, compact housing. Driven by a common shaft, this space-saving solution is built with an advanced hydraulically balanced port plate and a 12-vane rotor design, ensuring ultra-low pressure ripples and minimal noise during continuous high-pressure operations. Every double pump undergoes rigorous 100% full-load and dual-displacement simulated testing prior to shipment. Featuring exact international standard dimensions for mounting and porting, it provides seamless drop-in interchangeability with original Atos PFED models, making it the ultimate choice for upgrading system reliability and minimizing maintenance costs.

Key Technical Advantages:

• Space-Saving Dual Output: Driving two independent flow circuits from a single prime mover eliminates the need for a secondary motor or power take-off (PTO), significantly simplifying hydraulic plumbing and reducing footprint.

• Modular Cartridge Construction: Both front and rear pumping elements utilize an easily removable cartridge design. Kits can be replaced in minutes without disconnecting the main pump body from the hydraulic lines, slashing maintenance downtime.

• Hydraulic Balance & Low Noise: The hydraulically balanced internal design completely eliminates radial loads on the drive shaft bearings, extending service life. The optimized 12-vane configuration drastically reduces acoustic emissions compared to equivalent gear pumps.

• True Drop-In Interchangeability: Machined to precise OEM tolerances, the pilot diameter, mounting flanges, and shaft extensions exactly match original Atos specifications, allowing immediate plug-and-play replacement on existing equipment.

Application Areas:

• Plastic Molding Machinery: Dual-circuit injection molding machines requiring independent supply for high-pressure clamping and high-flow injection cycles.

• Industrial Machine Tools: Large-scale CNC machining centers managing main drive systems alongside auxiliary clamping or lubrication loops.

• Press & Metallurgical Equipment: Power units for hydraulic presses, shearers, and continuous casting lines in steel mills.

• Mobile & Heavy Equipment: Specialized machinery requiring synchronized or staged multi-actuator operations.

Expert Maintenance Tips:

• Dual-Chamber Pre-Filling: Before initial startup or after long storage, both the front and rear pump cavities must be completely filled with clean hydraulic fluid. Dry running will cause immediate and irreversible damage to the cam ring and port plates.

• Suction Line Cavitation Prevention: Since both stages share a single suction port, the total intake flow is substantial. Ensure the suction line is generously sized, leak-free, and the suction strainer capacity is at least 2.5 times the combined maximum flow of both pumps to avoid cavitation and severe noise.

• Shaft Torque Verification: As a single shaft drives two pumps, verify that the electric motor shaft and flexible coupling are rated to withstand the combined peak torque generated when both the front and rear pumps operate at maximum pressure simultaneously.
