4535V60A30-1AA22R Eaton Vickers Double Vane Pump 172Bar

Product Overview

The 4535V60A30-1AA22R is a heavy-duty, high-flow double hydraulic vane pump engineered for demanding industrial environments. Manufactured to stringent hydraulic engineering standards, it delivers 100% direct drop-in interchangeability with the Eaton Vickers 4535V series. Utilizing a classic dual modular cartridge kit design (a 45V front pump combined with a 35V rear pump) and advanced intra-vane technology, this unit supplies two independent, high-flow, high-pressure fluid sources driven by a single input shaft. It is the premier prime mover for systems requiring dual-speed (high-low) circuits or synchronized multi-cylinder operations. Before dispatch, every 4535V double pump undergoes 100% full-load simulated working condition testing to guarantee that its volumetric efficiency, anti-pulsation stability, and fatigue life perfectly match original OEM specifications. It provides an exceptional, cost-effective replacement solution to minimize procurement budgets and drastically reduce machinery downtime.

Key Technical Advantages

• Precision Intra-Vane Technology: This advanced system routes pressurized fluid into the cavity between the intra-vane and main vane, hydrostatically counteracting the massive outward centrifugal forces generated at high speeds. This wear-compensation mechanism drastically reduces contact stress on the cam ring, allowing the pump to sustain high volumetric efficiency (over 90%) even under continuous 172 bar pressure.

• Dual Modular Cartridge Kits: Both the front and rear pumps feature independent, self-contained cartridge kits comprising the rotor, cam ring, vanes, and pressure plates. For in-field maintenance, technicians can simply extract the worn cartridge and insert a new one without uncoupling the heavy pump housing from the motor bracket or disconnecting complex hydraulic plumbing.

• 100% True Plug-and-Play Interchangeability: Adhering strictly to SAE standards, the 4-bolt mounting flange, shaft dimensions, and port-to-port center distances mirror the original Vickers data perfectly. Customers achieve a seamless 1:1 replacement with zero need for welding, bracket modification, or pipe rerouting.

• Fully Hydrostatically Balanced Architecture: The internal cam ring features a dual-elliptical profile creating two diametrically opposed high-pressure and low-pressure quadrants. This engineered symmetry ensures that hydraulic radial loads acting on the rotor completely neutralize each other, entirely eliminating eccentric bearing wear and maximizing the operational fatigue life of the shaft and bearings.

Application Areas

Thanks to its robust dual-flow output and low-noise characteristics, the 4535V60A30-1AA22R double vane pump is heavily deployed in heavy-duty hydraulic machinery:

• Large Plastics & Die-Casting Machinery: Supplying rapid clamping and high-pressure injection dual-circuits for large-tonnage injection molding machines.

• Heavy Metal Forming Presses: Serving as the core power unit for hydraulic shears, press brakes, and forging presses requiring rapid-approach and slow-press dual-speed circuits.

• Material Handling & Baling Equipment: Powering scrap metal balers, rubber vulcanizing presses, and heavy-duty hydraulic lifting platforms.

• Industrial Hydraulic Power Units (HPU): Acting as the main centralized hydraulic power source for heavy metallurgical equipment and automated production lines.

Expert Maintenance Tips

• Mandatory Startup Bleeding & Priming: Because of its large displacement, starting this pump dry will cause instantaneous catastrophic failure. Before the initial start or after a cartridge rebuild, always pre-fill the pump casing with clean hydraulic oil through the highest port. Jog the electric motor 3 to 5 times (max 2 seconds per jog) to establish oil films and bleed trapped air before applying full system load.

• Strict Fluid Contamination Control: The micron-level internal clearances of high-pressure intra-vane pumps demand pristine fluid. Fluid cleanliness must be rigorously maintained at ISO 4406 Class 18/16/13 or better. Installing an absolute return-line filter rated at 10μm (or finer) is highly recommended.

• Inlet Vacuum & Cavitation Prevention: Given the massive fluid intake of this double pump, ensure suction lines are oversized, unobstructed, and free of excessive elbows. The inlet vacuum must never exceed 0.17 bar (5 in. Hg) during operation. High suction resistance will trigger severe cavitation, instantaneously stripping metal from the cam ring and producing a loud, high-frequency whining noise.
