Hydraulic Pump OEM A4VG Series Variable Displacement Swash Plate Axial Piston 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.High Power Density & Pressure:Handles extremely high continuous pressures (typically up to 400 bar), delivering significant power in a compact design.
2.Superior Efficiency: Optimized swash plate design minimizes internal losses, ensuring high volumetric and mechanical efficiency across the operating range.
3.Precise, Responsive Control:Enables smooth, dynamic adjustment of flow and pressure for optimal system performance and energy savings.
4.Robust & Reliable: Proven heavy-duty construction ensures long service life under demanding conditions.
5.Low Noise & Vibration:Advanced design features significantly reduce operational noise and vibration.
6.Electronic Control Ready: Easily integrates with modern electronic control systems (e.g., EP, DA, HW) for sophisticated functions.
7.Excellent Suction Performance: Designed for reliable operation with good suction characteristics.
8.Thermal Management:Efficient design helps manage operating temperatures.
9.Reduced Operating Costs: High efficiency and durability translate to lower total cost of ownership.
