OEM Hydraulic Pump For Agricultural Machinery Construction Machinery

• Internals: Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used.
• Buffering: Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
• Welding: 100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength.
• Sealing: All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
• Testing & Certification: Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates.
• Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period.

• Robust Design: Engineered for extreme dust, moisture, shock, and load cycles.
• High Efficiency: Optimizes fuel/power consumption and reduces operating costs.
• Precision Fit: Custom specs ensure seamless integration with specific machinery models.
• Reliable Performance: Consistent flow/pressure under heavy, continuous operation.
• Durability: High-grade materials resist wear, contamination, and harsh environments.
• Cost Savings: Wholesale OEM pricing lowers acquisition/maintenance expenses.
• High Torque: Delivers power needed for demanding tasks like digging or lifting.
