High temperature Metal Bellow is used for high temperature application such as refinery, Petrochemical & Chemical Industries. Due to its narrow seal cross section design, can replace most type of seal used in ANSI pumps. Secondary seals are made up of Grafoil which can withstand high temp upto 425 deg C. It is resistant to abrasive particles in pumpage and not Shaft / Sleeve fretting.
The edge welded bellows are produced by sta mping out a male and a female diaphragm and welding them edge to edge. These diaphragms typically have several ripples running from ID to OD.
These seals can be provided as Cartridge seals in Single and Double design. Metal Bellow Cartridge seal is ready to install Mechanical Cartridge Seal. All parts of Mechanical seal form a compact unit together with the shaft sleeve, casing parts, connection flange & torque transmission element. Cartridge seals benefit is to reduce down-time periods and enables mechanical seals to be installed in hand-to-access place. We have different Models like MBRC , MBSC, MBR DC & MBS DC to suit the various applications.
MBR Seal has a Rotating bellow assembly where as MBRC is a Rotating Bellow Single Cartridge assembly . MBRDC is a Rotary Bellow Double Cartridge assembly.
