Key Technical Advantages:

• High-Pressure Axial Design: Features high-performance tapered roller bearings and high-strength piston groups, ensuring mechanical stability and extended service life under 350 bar continuous operating pressure.

• Optimized Flow Path: Internal flow geometries are computer-simulated to minimize throttling losses at high flow rates, significantly enhancing overall volumetric efficiency.

• Elite Suction Capability: Advanced port-plate design ensures superior self-priming capability even during cold starts or extreme operating conditions, effectively mitigating cavitation risks.

• Seamless Compatibility: Manufactured to strict Rexroth A17FO specifications, ensuring identical mounting footprints, shaft dimensions, and port layouts for a true “plug-and-play” replacement.

Application Areas:

• Mobile Machinery: Auxiliary power sources for concrete pump trucks, mixers, and heavy engineering vehicles.

• Industrial Manufacturing: Hydraulic presses, metal-forming equipment, and large-scale centralized power units.

• Marine & Drilling: Hydraulic winch drives and power transmission systems for drilling rigs.

Expert Maintenance Tips:

• Inlet-Side Integrity: Piston pumps are highly sensitive to suction-side leaks. Ensure all intake connections are airtight using high-grade gaskets to prevent air ingestion.

• Filtration Standards: Maintain ISO 4406 18/16/13 fluid cleanliness standards. If fluid becomes discolored or contains metallic particulates, perform an immediate oil and filter change.

• Pre-fill Before Startup: Always fill the pump housing with clean hydraulic fluid through the case-drain port before the initial start to ensure immediate lubrication of the rotating group.
