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

Premium Quality Hydraulic Cylinders - Quality Assured

1. 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.
2. Buffering:Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
3. 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.
4. Sealing:All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
5. 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.
6. Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period. Advantages:1. Precision Variable Control:Swashplate design enables real-time flow/pressure adjustment for optimal compaction speed and force.
2. High Efficiency:Minimizes energy loss during vibration and travel modes, lowering fuel costs.
3. Rugged Construction:Reinforced bearings/seals withstand shock, dust, and temperature extremes on construction sites.
4. Contamination Resistance:Optimized clearances and filtration compatibility extend component life.
5. Reduced Vibration/Noise:Balanced piston design ensures smoother operation and operator comfort.
6. Extended Durability:Hardened materials and OEM customization prevent wear under high-pressure cycling.
7. Seamless Integration: Tailored mounting, shaft, and porting for exact roller hydraulic system fit.
8. Dedicated OEM Support: Application-specific expertise for maintenance and performance optimization.
