PVG-100-F1UV-LSFY-F-1NN/FNN Oilgear Hydraulic Pump 345 Bar

Product Overview

The PVG-100-F1UV-LSFY-F-1NN/FNN axial piston variable displacement pump (built on the renowned Oilgear PVG 100 platform) is engineered for high-pressure open-loop hydraulic systems and heavy-duty industrial or mobile machinery. Manufactured strictly to Oilgear OEM technical standards, this pump guarantees 100% direct drop-in interchangeability. Every unit undergoes 100% factory bench testing under simulated high-pressure full-load conditions to ensure maximum volumetric efficiency, fast control response, and exceptional durability even when operating with low-viscosity fluids.

Key Technical Advantages

• 100% Direct Drop-in Interchangeability: Precision-machined mounting flanges, drive shafts, and fluid ports strictly match Oilgear OEM specifications, enabling seamless plug-and-play installation without piping modification.

• Proprietary Hard-on-Hard Technology: Features Oilgear’s advanced hard-on-hard rotating wear surfaces, offering superior contamination tolerance and extreme wear resistance under high-pressure conditions.

• Hydrodynamic Barrel Bearing Support: Utilizes a proprietary hydrodynamic bearing to support the cylinder barrel, reducing overall envelope size, minimizing noise, and absorbing heavy radial stress.

• Fast-Response Four-Way Pilot Control: Incorporates a high-response pilot-operated control system to achieve near-instantaneous displacement adjustments and precise load-sensing performance.

Application Areas

• Industrial Heavy Machinery: Primary hydraulic power source for metal forging presses, stamping machines, injection molding units, and extruders.

• Mobile & Offshore Equipment: High-pressure hydraulic drives for heavy-duty cranes, oilfield drilling rigs, mining machines, and marine deck equipment.

Expert Maintenance Tips

• Case Priming Prior to Startup: Fill the pump casing completely with clean hydraulic fluid through the highest case drain port before initial operation. Operating the pump dry will cause immediate internal damage.

• Fluid Cleanliness Management: Maintain oil cleanliness at or cleaner than ISO 4406 18/16/13 to protect the precision pilot control valve and internal rotating group.

• Inlet Line Vacuum Inspection: Periodically check suction lines and flange seals to prevent air ingestion, which leads to cavitation and premature wear.
