  • Vertical, Top-Entry Tank Mounting eliminates potentially hazardous side or bottom connections.
  • A Gas Mechanical Seal provides the lowest fugitive emissions without complex piping, instrumentation or regulation. A complete instrumentation package is available to control the flow of buffer gas to the seal chamber and monitor critical operating parameters.
  • An Optional Emergency Seal isolates the storage vessel from the atmosphere should a packing or mechanical seal failure occur.
  • An Optional Excess Flow Check Valve operates independently to stop the flow of liquid chlorine should a downstream line rupture occur while the pump is running.
  • Numerous Materials of Construction are available to suit application requirements.
  • The Diffuser Casing Design completely balances the radial thrust.
  • Regardless of the number of stages used, or the head developed by the pump, the radial load carried by the sleeve bearings is minimal.
