Mechanical Seal for Lowara SV/SVI Pump | Sealing Tech-G

The Sealing Tech-G Lowara SV/SVI Pump Mechanical Seal is a direct replacement seal specifically designed for Lowara SV and SVI series vertical multi-stage centrifugal pumps, ensuring a secure, leak-free, and long-lasting seal in high-pressure applications. Available in 2 shaft diameters: 12 mm and 16 mm, with Carbon-Silicon (C/SiC) faces and an EPDM elastomer. The C/SiC combination offers superior chemical, thermal, and mechanical resistance compared to conventional ceramic seals, making it the optimal choice for the demanding operating conditions of vertical multi-stage pumps. Origin: Spain / Taiwan. Manufacturer: Sealing Tech-G.

Sealing Face Materials

• Carbon/Graphite (rotating face): Self-lubricating, low friction, and excellent wear resistance. Performs well in clean water and low-viscosity fluids.
• Silicon Carbide — SiC (stationary face): Maximum hardness, resistance to abrasive fluids and high temperatures. Superior to conventional ceramic in high pressure and temperature conditions.
• EPDM Elastomer: Resistant to hot water, steam, glycols, alkaline fluids, and diluted acids. Temperature range: -40 °C to +150 °C. Not compatible with mineral oils or hydrocarbons.

Applications

• Direct replacement for shaft seals in Lowara SV and SVI series vertical multi-stage pumps.
• Potable and industrial water pressure systems: high-pressure pumps for buildings, industry, and municipalities.
• HVAC and air conditioning systems: hot and cold water circulation pumps in high-demand installations.
• Technified irrigation and water supply systems: pressure pumps for agriculture and water infrastructure.
• Water treatment industry: high-pressure pumps for reverse osmosis, filtration, and distribution.
• Applications with aggressive or high-temperature fluids where conventional ceramic is insufficient.
• Preventive and corrective maintenance of Lowara SV/SVI pumps in industrial, commercial, and infrastructure installations.
