Double Mechanical Seal

Seal Type : MFI-DBL 800

The Series 800 are multi spring double mechanical seal design where absolute leak proof sealing is necessary due to toxic, hazardous nature of fluid. This seals is a combination of two conventional seals installed back to back inside stuffing box.

The inner seal prevents the circulated fluid to enter the system and the outer seal prevents it from leaking it to atmosphere. The circulation of the fluid reduces the heat generated on the seal faces. This seals are available in different design combination suiting to service conditions.
