High Temperature Bellow Seal

This design is comply with api682 technical requirements and has the flexibility to fit into ansi+ and din standard pumps

Metal Bellow Seals of MB1 are commonly used for moderate Temperature Oils & Hydrocarbons, MB1 provides a high degree of axial flexibility to compensate for lack of concentricity of the shaft or misalignment due to thrust movement of the shaft. Moreover, these seals are used for high temperature application such as refinery, Petrochemical, and Oil & Gas industries. These seals do not have a dynamic o rings eliminating the fretting of Shaft or Sleeve.

Salient features:

Welded Diaphragm Bellow Design
Suitable for High Temperature Media.
Axial compensation of movement 1 mm.
Perfect for standardization purposes.
No Dynamic O Rings
Inherently Balanced Design
