Helpful Hints

  • Add emulsions to water only
  • Ensure very high shear at polymer and water interface
  • Use soft tempered water 20-30 Deg. C
  • Standard Emulsions 30 -35 % Active
  • Concentrations .25 – 1.5% – consider Neat Polymer as 100% active when calculating feed rates
  • Modulate polymer flow – not water – keeps systems cleaner with higher flow & pressure
  • PC pumps recommended for neat polymer feed
  • Agitate Neat Polymer
  • Use “Desiccant Dryer” on Neat Polymer tank vent if high humidity is a concern
  • Pumps SS/Viton – shaft speeds 450 rpm max., ENSURE flooded suction
  • Consider Bag Filters in applications as advised by your chemical supplier
  • “Critical” polymer application avoid direct to process system, use mix/age tank where possible
  • Consider 20 – 30 minutes age time (use tanks when possible)
  • Prevent leaks; avoid using water to clean spills, emulsions are very slippery when water is added
  • For spills consider using dri-rite material and sweep up

Neat Polymer Feed Pumps – intermittent use;

  • re-cycle polymer to neat storage vessel – or/
  • Flush with mineral oil
  • W/ Mineral oil lay-up Rotate pumps each month
  • Inspect and clean check valves after usage

Process Feed Pumps – intermittent use;

  • Flush with water rotate at low speed
  • Lay-up with mineral oil
  • W/ Mineral oil lay-up Rotate pumps each month
  • Inspect and clean check valves after usage

Neat Storage Tanks;

  • Do not flush or use water
  • Inspect for build-up on side wall
  • May require high pressure hot water , ensure all water is removed & completely dried before going back in service

Application Tanks – intermittent use;

  • Flush with water after each use
  • Remove as much water as able, not a problem for these tanks to have water in them
  • Neat Polymer – Maintain consistent temperature & low humidity
