TG74UWave Spring, O-ring pusher mechanical seal Type TG71U is a robust and highly interchangeable seals. Used in the different media conditions due to extend material options. It is ideal for use in paper industry, textile printing, chemical petroleum, shipbuilding and sewage treatment industry.
Wave Spring, O-ring pusher construction Transmission by Pin and groove，independent of direction of rotation . Solid seal faces material are easily interchangeable. Good heat dissipation Low risk of clogging in solids content or viscous liquids Can meet two standard dimensions when change in stationary seat
Paper and textile printing industry, petrochemical industry and sewage treatment industry Low solids content or viscous media Sewage pumps, chemical pumps, screw pumps, Gear wheel feed pumps and multistage pumps Other Rotating Equipment.
