Description

Unpressurised external buffer fluid circulation from a central pressure source or by a stand alone pumping unit.

Features

  1. Ensures higher flow rate, better heat dissipation and positive circulation of buffer fluid.
  2. Can also be given as a stand-alone unit per pump.
  3. Increases cooler efficiency due to higher flow rate to the heat exchanger
  4. No process contamination.
  5. No direct leakage to atmosphere.

Use

  1. For media where product dilution is not allowed but leakage to atmosphere in diluted form may be allowed.
  2. Preferred for clean, non-polymerizing media that may solidify in contact with atmosphere.
  3. For media with high pressures and/or high temperature and/or high heat generation between faces.
  4. Wherever Plan 52 circulation is insufficient to dissipate heat.

Caution

  1. Carefully consider the reliability of buffer fluid source, if a central source is used.
  2. Circulating system pressure must be less than seal chamber pressure and less than 28bar.
  3. Always check filter/strainer in the system for any possible blockages.
  4. Not suitable for polymerizing media.
  5. Ensure suitable flow is maintained at all times.
