Hydraulic Plunger Pump For Road Roller Swashplate Hydraulic Axial Piston Variable Pump

Premium Quality Hydraulic Cylinders - Quality Assured

• 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.
• 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.
• Testing & Certification: Factory testing strictly complies with GB/T15622-2005 standards and internal premium standard Q/GAKY014-2023.
• Warranty: One-year warranty from shipment date with free repair or replacement for defects.

• Precision Variable Control: Swashplate design enables real-time flow/pressure adjustment
• High Efficiency: Minimizes energy loss during vibration and travel modes
• Rugged Construction: Reinforced bearings/seals withstand shock, dust, and temperature extremes
• Contamination Resistance: Optimized clearances and filtration compatibility
• Reduced Vibration/Noise: Balanced piston design ensures smoother operation
• Extended Durability: Hardened materials and OEM customization prevent wear
• Seamless Integration: Tailored mounting, shaft, and porting
• Dedicated OEM Support: Application-specific expertise
