type 1 mechanical seal in stock

A pusher-type seal consists of a primary sealing ring assembled with an "O" ring and springs which force the sealing liquid across the face and keep it from leaking to the ID side of the seal.

The dynamic O-ring is designed to be pushed axially along the shaft. The surface underneath the dynamic Oring must therefore be very smooth to allow for axial movement. If solids are abundant in the sealing fluid, they can build up on the o-ring and prevent this axial movement.

Pusher types seals are less expensive and are readily available in a wide range of sizes and designs. The only disadvantage being a tendency to hang up and fretting of the shaft.

The global mechanical seals market size stood at USD 3.20 billion in 2018 and is projected to reach USD 4.77 billion by 2026, exhibiting a CAGR of 5.2% during the forecast period.

The key utility of a mechanical seal is to prevent leakage of fluids or gases through the clearance between the shaft and the container. Mechanical seals consist of a set of 2 faces separated by carbon rings. The first face is in contact with the rotating equipment whereas the second face is stationary. Moreover, the main part of the seal is the seal ring (first face) on which the mechanical force is acting, generated by springs, bellows, or fluids in the equipment. In recent years, mechanical seals are playing an important role in varied industrial applications, enabling efficient operations. Mechanical seals are made up of several flexible materials such as Polytetrafluoroethylene (PTFE), Polyurethane (AU, EU), industrial rubber, Fluorosilicone (FVMQ), and many more.
