Seal Support System

Seal Support System

Liquid-lubricated dual mechanical seals require an external source of clean, cool lubricating fluid. The ANSI LITE barrier fluid reservoir system creates this enhanced sealing environment, enabling longer operational life for dual seals. The closed loop system allows for monitoring of the inboard seal, noting changes in the ANSI LITE barrier fluid reservoir’s levels.

Features

Standard Options:

Plan 52 – Used with Unpressurized Barrier Fluid

  • Tank with aluminum tubular level gauge
  • ½” NPT bronze vent & drain ball valves
  • 304 stainless steel orifice union
  • 2½” dial 316 stainless steel pressure gauge (0-160 PSI)

Plan 53 – Used with Pressurized Barrier Fluid

  • Tank with aluminum tubular level gauge
  • ½” NPT bronze vent & drain ball valves
  • 2½” dial 316 stainless steel pressure gauge (0-160 PSI)

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 is a visual tool to inform the operator 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.
