Double End Face Mechanical Seal Alternative to Alfa Laval Pump Seal

Double End Face Mechanical Seal Alternative to Alfa Laval Pump Seal

Item: DL-AL-05
Brand Name: DaoLin
Type: Replacement Seal

Product Name: Double end face mechanical seal alternative to Alfa Laval pump seal


Description:

Double end face seal arrangement is intended to seal the barrier liquid, not the process liquid. The arrangement consists of an inner or primary seal installed in backward position, and an outer or secondary seal installed in normal position. The backward position of the inner seal prevents the barrier liquid from entering the pump at normal condition. In the event of an inner seal failure the barrier liquid enters the pump and prevents the process liquid from leaking into atmosphere. In the event of outer seal failure, the non-hazardous barrier liquid leaks into atmosphere while the inner seal contains the process liquid.
