3.3 For dual seal un-pressurized operation, supply a clean

compatible buffer uid to the inlet port at a pressure below the

stufng box pressure. See Figure 9. Consult your Flowserve Sales

and Service Representative for assistance. Flowserve can supply

information on buffer uid ow requirements based on seal size,

product temperature, barrier uid characteristics, and shaft speed.

3.4 The Flowserve Supply Tank is designed to work with the CPM

PP seal to form a self-contained sealing system. The circulating

feature in the CPM PP seal 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 CPM PP seal in both the dual pressurized or dual

unpressurized operating modes.
