TG120BTG120B is conical spring and O-ring pusher construction mechanical seals,designed for large batch production. This type of mechanical seal is easy to install. covers a wide range of applications and reliable performance. It is frequently used in paper industry,sugar industry, chemical and petroleum, food processing, sewage treatment industry.
Conical spring,unbalanced,O-ring pusher construction Torque transmission via conical spring, independent of direction of rotation. Wide option in seal face material 。 Spring with deep coils to reduce the risk of clogging in solids content or viscous liquids.
Paper and sugar industry,Food Processing,waste water technology Low solids content or viscous media Sewage pumps, chemical pumps, screw pumps, process pumps Other Rotating Equipment.
