slurry pump seal manufacturer in China
– Engineered for Abrasive & Corrosive Media
Custom-engineered mechanical seals for slurry, mining, and dewatering pumps.Designed for long life in abrasive, high-solid, and high-pressure environments.
Sealing Challenges for Slurry Pumps
When conveying high-concentration, highly abrasive media with substantial solids content, slurry pumps face exceptionally demanding sealing conditions. Particles within the slurry continuously erode the sealing surfaces, leading to wear, blockage, and leakage.Furthermore, the media often contains acids, alkalis, or corrosive chemicals. High temperatures, pressures, and pump shaft vibrations further exacerbate seal failure.
Consequently, conventional seals or packing struggle to withstand such conditions. Only mechanical seals specifically engineered for slurry applications can effectively address this issue. Slurry pump mechanical seals offer wear resistance, corrosion resistance, flushability, and automatic compensation, enabling long-term, stable, leak-free operation in these extreme environments.
Sakowit slurry pump seals are precisely engineered for this purpose, serving heavy-duty slurry systems in mining, desulfurization, power plants, chemical processing, and other industries.
