Product Name: High durability double mechanical seal for corrosive fluids


Description:

Double mechanical seal is a combination of two seals mounted either back-to-back, or single seal having sealing faces on both sides or tandem type. These seals can be single-coiled or multi springs type besides they can have a combination of unbalance / unbalance, unbalance / balance or balance / balance tandem types. These seals are suitable for handling media which otherwise cannot be handled by single seals. For cooling the seal faces during operation, a clear compatible liquid is circulated between two seals at a higher pressure of one bar than the pumped liquid. The internal seal prevents the liquid from entering the circulation system while the external seal prevents it from leaking to the environment.
