Industrial Hydraulic Pumps OEM Fluid Power Pumps High Pressure Oil Pumps

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:Extreme Pressure Capability:1.Engineered for reliable, continuous operation at very high pressures (often 350 bar+), delivering significant power density.
2.High Efficiency:Optimized designs minimize internal leakage (volumetric loss) and friction (mechanical loss), reducing energy consumption and heat generation.
3.Robustness & Long Life: Heavy-duty construction withstands harsh industrial environments, shock loads, contamination, and demanding duty cycles.
4.Precise Flow & Pressure Control: Enables accurate system operation and responsiveness, critical for complex machinery.
5.Custom Integration:OEM tailoring ensures optimal mounting, porting, shaft interfaces, and control compatibility for seamless machine integration.
6.Wide Application Range:Versatile designs (gear, vane, piston) suit diverse needs from mobile equipment to factory automation.
7.Proven Reliability: Utilizes established, field-tested hydraulic technologies. It is usually composed of a buffer plunger, a buffer chamber, and an orifice. Buffer plunger: generally installed at the end of
the piston rod or cylinder head of the oil cylinder. When the oil cylinder reaches the end of its stroke, the buffer plunger first
enters the buffer chamber. Buffer chamber: It is a specially designed space connected to the working chamber of the oil cylinder. When the buffer plunger
enters the buffer chamber, it compresses the oil inside the buffer chamber, thereby generating a buffering force. Throttle hole:
set between the buffer chamber and the working chamber, or on the buffer plunger. The size and number of throttle holes can adjust
the magnitude and buffering effect of the buffering force.
