Seal Support System

ANSI Lite Barrier Fluid Reservoir

Capacity:
(3) Gallons 11.5 liters

Tank Material:
304 S.S.

Max. Working Pressure:
160 PSIG at -20 to 100F 11.3 kg/cm2 to -29 to 38C

Liquid lubricated dual mechanical seals require an external source of clean, cool lubricating fluid. By using a dual seal with the ANSI LITE BARRIER FLUID RESERVOIR system it will provide an enhanced sealing environment which promotes longer seal life.

This closed loop system allows the ability to determine the condition of the inboard seal by noting changes in the fluid level of the ANSI LITE BARRIER FLUID RESERVOIR.

Basic Reservoir:

Tank with Aluminum Tubular Level Gauge

Flex-A-Seal WCS2 Water Conservation system utilizes the pressure available from the plant water line to pressurize the barrier fluid inside the reservoir. This provides a pressurized barrier fluid that maintains a clean, cool stable fluid film across the seal faces. The check valve protects the plant water line from process contamination and also maintains the maximum pressure from the plant water line. The Sight Flow Indicator visually makes the user aware that an inboard seal leak has occurred. The WCS2 is a self regulating system which can both refill and re-pressurize itself upon any mechanical upset.

Note: To control the Barrier Fluid temperature all of the options above can be supplied with 316 S.S. ½“ cooling coils inside the tank.
