Engineered for extreme desert dust, high pressure, and heavy mechanical stress
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, evolving from the Xianyang Kelong Rubber Products Institute. Over the last 27 years, we have grown into a high-technology innovation powerhouse integrating R&D, production, and sales. We specialize in engineering high-pressure hydraulic seal sets, robust rubber seals, and high-pressure hose products designed for the most punishing industrial environments globally.
Equipped with Austrian-imported DMH manufacturing systems and state-of-the-art Italian hydraulic hose production lines, Shaanxi Kelong supplies elite engineering solutions across the globe. Our advanced seal components are trusted by top-tier enterprises in coal mining, civil aviation, high-speed rail, offshore energy, and wind power generation.
Namibia is home to some of the world's most intense mining, marine maritime, and infrastructure sectors. Operating hydraulic components in the Erongo Region's massive open-cast uranium mines (such as Husab and Rössing) or handling deep-sea offshore diamond extraction along the Sperrgebiet coast places extraordinary stresses on sealing materials. Traditional seals deteriorate rapidly when subjected to Namibia's characteristic atmospheric extremes: ultra-fine, abrasive silica desert dust, severe UV radiation, and high marine salinity.
This is where Shaanxi Kelong's engineering value becomes critical. Rather than offering basic elastomeric rings, we formulate material matrices specifically for intense abrasive zones. Our polyurethanes (PU) feature unique molecular chains that prevent hydrolysis in saltwater, while our PTFE compound seals exhibit superior resistance to sand particles that cause premature rod pitting and fluid leaks. By extending mean time between failures (MTBF) from months to years, we significantly lower operational downtime for Namibian heavy equipment.
In Namibia's dry desert and coastal mining operations, fine abrasive particles breach standard hydraulic seals, scratching the cylinder rod and causing catastrophic oil leaks. Our specialized KL-93 Double-Lip Wiper Seal features an optimized geometric lip configuration that acts as a dry scraper, excluding up to 99.8% of micro-particulates, preserving hydraulic oil integrity and extending cylinder life cycles.
The global sealing industry is shifting from traditional passive elastomeric rings to smart, high-durability polymer compounds. Modern heavy engineering demands materials that survive higher pressure profiles, wider temperature ranges, and less lubrication. Key trends include:
| Material Type | Operating Temp Range | Max Pressure Limit | Primary Strengths in Namibian Operations |
|---|---|---|---|
| PTFE (Carbon/Bronze Filled) | -60°C to +200°C | 60 MPa | Zero stick-slip, superior chemical resistance, exceptional dry-running ability. |
| Specialized Polyurethane (PU) | -35°C to +110°C | 40 MPa | Outstanding wear resistance, high tear strength, superb extrusion resistance. |
| NBR (Nitrile Rubber) | -30°C to +120°C | 15 MPa (Static) | Excellent mineral oil compatibility, cost-effective static and low pressure sealing. |
| FKM (Fluorocarbon) | -20°C to +200°C | 35 MPa | Resistant to high chemical aggression, ozone, weathering, and intense acids. |
Uncompromising quality assurance from raw polymers to high-pressure certified hoses
Our custom seals are machined using manufacturing centers and processing technologies imported from DMH Company in Austria, allowing us to hit dimensional tolerances within micrometers.
Our hydraulic hose base utilizes complete manufacturing systems imported from Italy. We produce ultra-resilient wire-spiral and braided hoses designed to thrive under continuous dynamic pulsing.
Operating with certified ISO 9001 and IRIS systems, Shaanxi Kelong ensures that every sealing element and hose undergoes 100% inspection before departing our facility.
