Elastomer Bellows mechanical seal
Elastomer Bellows mechanical seal

Elastomer bellows mechanical seal is indentified by the use of an elastomer bellows or diaphragm for the secondary sealing member. Elatomer bellows seal units require a positive abutment at the back of the bellows or spring, positioned so as to give the correct seal working length

O-ring Pusher Mechanical seals
O-ring Pusher Mechanical seals

O-ring Pusher seals use a sliding secondary seal and in this design the O-ring is pushed along the outside diameter of the equipment shaft or sleeve. The O-ring retains the sealed liquid and follows along the shaft to compensate for face wear.

PTFE Bellows Mechanical seals

Type 10T and 10R both use PTFE bellows, and are designed for external mounting on extremely corrosive duties including acids, salts and organic compounds.

Metal Bellows Mechanical seals
Metal Bellows Mechanical seals
