Key Technical Advantages:

• High-Pressure Hydraulic Balance: Incorporates an advanced hydraulic balance port-plate design that automatically compensates for internal clearances, maintaining high volumetric efficiency even under continuous 210 bar heavy-duty cycles.

• Ultra-Low Noise Performance: Features a 12-vane rotor geometry and optimized internal fluid passage design that significantly reduces pressure ripples, delivering a quiet working environment tailored for modern industrial plants.

• Interchangeable Cartridge Design: Utilizes a modular internal cartridge kit that can be replaced within minutes without disconnecting the main pump body from the piping or motor bracket, minimizing maintenance downtime.

• True OEM Interchangeability: Engineered strictly to international SAE standards for mounting pilots, flanges, and shaft configurations, ensuring a direct drop-in replacement without the need for piping modifications.

Application Areas:

• Industrial Machine Tools: Hydraulic power systems for CNC machining centers, milling machines, and specialized multi-axis metal-cutting machines.

• Plastics & Rubber Machinery: Injection molding units, calendering machines, and rubber vulcanizing presses.

• Metallurgy & Heavy Equipment: Continuous casting lines, auxiliary rolling mill machinery, and heavy industrial hydraulic stations.

• Marine & Mobile Systems: Deck machinery, material handling equipment, and fixed hydraulic power packs.

Expert Maintenance Tips:

• Initial Pre-Lubrication: Prior to first startup or after extended storage, completely fill the pump casing with clean hydraulic fluid through the drain/fill port. Dry running is strictly prohibited to prevent immediate scuffing of internal elements.

• Thermal & Viscosity Control: Maintain fluid operating temperatures between -20°C and +60°C (for standard nitrile seals) to prevent oil thinning and breakdown of the lubricating film. For continuous operation above 60°C, specify the optional PE seal variant.

• Routine Filtration Monitoring: High-pressure vane pumps demand rigorous fluid cleanliness. Regularly inspect and service inlet strainers and return-line filters to prevent particulate contamination from scoring internal plates or causing valve sticking.
