4.4 The Flowserve Supply Tank is designed to work with the ISC Dual

Seal to form a self-contained sealing system. The new circulating

feature in the ISC provides a positive barrier uid ow from the seal

cavity to the Supply Tank and back to the seal. In most cases the

natural cooling of the piping and tank are adequate to remove seal

generated heat. Cooling coils are available with the Supply Tank to

increase heat dissipation. The Supply Tank can be used with the

ISC dual seal in both the dual pressurized or dual unpressurized

operating modes.

Recommendation: For enhanced seal performance and reduced

coking, use DuraClear as a barrier uid. Refer to DuraClear brochure

FSD123 or contact a Flowserve seal application engineer for further

details.
