MOC: Carbon, Silicon, TC | SS304, SS316, SS316L
Metal Bellow Mechanical Seals
Welded metal bellow (non-pusher) seals with no dynamic O-rings, eliminating hang-up and fretting corrosion. Superior fatigue resistance for high-temperature, high-pressure applications. PTFE, Viton, and Grafoil secondary sealing options for extreme chemical compatibility.
MOC: Carbon, Silicon | SS304, SS316, SS316L
PTFE / Teflon Bellow Mechanical Seals
Chemically inert PTFE and GFT (Glass Filled PTFE) bellow seals for handling strong acids, alkalis, and oxidizing agents. Available in GFT and RCF bellow types with SS clamp construction. Purpose-built for pharmaceutical, chemical processing, and food-grade applications.
MOC: GFT, Carbon, Silicon, TC | SS304, SS316, SS316L
Double Mechanical Seals
Dual-seal arrangement providing an additional barrier for hazardous, toxic, or volatile media. Face-to-face and back-to-back configurations with SS housing and key washer assembly. Essential for applications requiring zero-emission sealing in chemical, dairy, and refinery environments.
MOC: Carbon, Silicon, TC, Ceramic | SS304, SS316, SS316L
Cartridge Mechanical Seals
Pre-assembled, pre-set cartridge seals for straightforward installation and removal — no shaft measurements needed. Single acting, balanced, inside mounted with multi-spring design and sturdy drive mechanism. Available in standard and GUF variants for paper, petrochemical, and refinery applications.
MOC: Carbon, Silicon, TC | SS304, SS316, Alloy-20, Hastelloy
Agitator Mechanical Seals
Heavy-duty single and double seal configurations designed for top-entry and bottom-entry agitators, mixers, and reactors. Single acting, multiple coil spring, balanced design with independent direction of rotation. Handles axial and radial shaft movement in chemical vessels.
