The MW-200 Seal design is engineered to operate with a liquid

barrier uid supplied to the seal chamber at a consistent pressure

2 bar (25 psig) above the maximum vessel pressure. Cooling water

may be required to cool the seal chamber. The liquid barrier uid must

be compatible with the process uid. The liquid barrier uid to be used,

maximum vessel pressure, shaft speed, temperature, equipment, and

shaft size must be specied when the seal is ordered. Do not attempt

to use this seal under other conditions without consulting Flowserve.

A supply tank with a pressure source and pressure gauge are

recommended. Install cooling water piping to the canister cooling

coils if required. See Figure 2.
