Pusher Mechanical Seals
A non-pusher type seal consists of a bellows assembly. The bellows is a component that acts as both the load element (like a spring in a pusher type) and a secondary sealing element (like an ‘O’ ring in a pusher type). Because the bellows prevents any leakage to the atmospheric side of the seal, and has a large clearance between itself and the shaft or sleeve, it can move freely in the axial direction (no dynamic ‘O’ ring), reducing the potential for hang up.
It is a Compact Single Spring Rubber Bellow Mechanical Seals for universal general purpose for Water / Water Based Solution like Oils, Fuels and Other Fluids and even with some Content with Abrasive and for a very wide operating condition designed for Centrifugal Pump. Rotary Equipment and Industrial applications (Food Processing, Water System, Waste Water Treatment for Petrochemical Processing, Pulp and Paper)

Metal Bellow mechanical seals are destined for petrochemical, chemical, pharmaceutical and food processing industry, for process pumps and other equipment with rotating shaft. Rotating bellows design acts to clear convolutions and prevent accumulation of debris. These bellow seals are constructed by welding a series of diaphragms together at the edges to form a bellows unit. Recommended for high temperature mediums e.g. hot oils, pitch, tar and other hydrocarbons, fuels, liquid gases and other mediums with low content of abrasives.
