• Fluid Compatibility: Mineral oils, synthetic hydraulic fluids

Key Technical Advantages:

• Superior Variable Response: Features a high-response pressure compensator that adjusts the swashplate angle instantaneously according to load changes, providing smooth flow regulation. This minimizes pressure overshoot and system oscillation, enhancing actuator control precision.

• Precision Valve-Plate & Wear-Resistant Coatings: Utilizes high-performance valve-plate technology with precision-honed piston components. This ensures micron-level sealing even under 280 bar pressure, pushing volumetric efficiency to the limit and reducing energy waste and heat generation.

• High-Rigidity Cast Iron Housing: The pump body is crafted from high-strength cast iron, providing exceptional vibration damping and structural rigidity. This ensures shaft concentricity and prevents bearing wear caused by body deformation under high-frequency 300 bar load cycles.

• 100% Drop-in Interchangeability: Genlu strictly adheres to Vickers original technical specifications, from SAE flange standards to splined shaft angles and control port threads. This ensures a seamless 1:1 replacement, drastically simplifying maintenance and equipment upgrade processes.

Application Areas:

• Industrial Presses: Forging presses and high-performance injection molding power systems.

• Metallurgical Equipment: Lubrication pressure supply for continuous casting machines and hydraulic shear power units.

• Port Logistics Equipment: Hydraulic drives for crane rotation and hydrostatic transmission systems.

• Heavy Construction Machinery: Auxiliary systems for tunnel boring machines (TBMs) and large crushing/screening plants.

Expert Maintenance Tips:

• Case Priming Protocol: Before initial start-up, manually prime the pump by filling the housing with clean hydraulic oil through the top case-drain port. This ensures full lubrication and prevents initial dry-start friction.

• Fluid Cleanliness Standards: PVM pumps are highly sensitive to contaminants. Use high-performance 10μm filtration to maintain fluid cleanliness at ISO 4406 17/15/12 standards.

• Case-Drain Back-Pressure Control: Ensure the case-drain line is clear and unrestricted. Direct this line straight to the reservoir (avoid shared return paths) to prevent internal pressure buildup, which can lead to front shaft seal failure.
