3 Liquid Barrier Supply
The MW-200 Seal design is engineered to operate with a liquid
barrier fluid 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 fluid must
be compatible with the process fluid. The liquid barrier fluid to be used,
maximum vessel pressure, shaft speed, temperature, equipment, and
shaft size must be specified when the seal is ordered. Do not attempt
to use this seal under other conditions without consulting Flowserve.
4 MW-200 Seal Piping
4.1 Install piping for the liquid barrier fluid to the canister taps.
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.
4.2 Bearings (optional) have been pre-lubricated during seal assembly.
