Engineered to comply with ISO 3601 & GOST standards for high-pressure hydraulic infrastructure in Samara.
Samara stands as one of the Russian Federation's most critical manufacturing and technological epicenters. Encompassing massive aerospace manufacturing complexes, automotive production lines (including the extended supply chain for AvtoVAZ in nearby Tolyatti), petrochemical processing along the Volga River, and heavy machinery production, Samara requires specialized fluid sealing architectures capable of surviving severe operational stresses.
The operational context of Samara presents a dual challenge for elastomeric component engineering: continuous high mechanical loads combined with aggressive thermal cycling. Ambient temperatures in the Samara Oblast swing dramatically from extreme winter freezes of -40°C to blistering summer highs exceeding +40°C. In hydraulic machinery, petroleum refining pumps, and heavy excavation gear, conventional off-the-shelf rubber seals suffer rapid micro-cracking, loss of radial lip energization, compression set failure, and fluid contamination.
Shaanxi Kelong New Materials Technology Co., Ltd. brings decades of specialized R&D to solve these tribological issues. Integrating European manufacturing technology from Austrian DMH systems and high-precision Italian extrusion bases, our product line delivers extended seal life, lower friction coefficients, and zero-leakage security under system pressures up to 80 MPa.
Domain-specific seal formulations designed to maximize Mean Time Between Failures (MTBF).
Serving Samara's tier-1 automotive manufacturing corridors. Our customized Polyurethane (PU) rod seals and dual-lip wipers maintain sealing integrity in automated assembly robotic arms, stamping hydraulic rams, and heavy commercial chassis suspension units.
Samara is world-renowned for space rocket and aviation engineering. We supply high-precision PTFE energized rings and low-friction bronze-filled rod seals engineered to operate seamlessly under severe low-temperature flight conditions and rapid pressure oscillation.
Volga oil refineries require elastomeric seals resistant to sour gas, hydrocarbons, and aggressive solvents. Our high-grade Fluoroelastomer (FKM) and modified NBR compounds prevent volatile organic compound (VOC) emissions and seal failures in process pumps.
