  • Agitator can easily put heavy solids into suspension to be pumped away with the liquid
  • Replaceable wear plate’s hardened surface on the suction side prevents erosion
  • Impeller can handle abrasive solid concentrations as high as 70% by weight
  • Include a top discharge and slim design that allows them to fit into tighter and thin spaces
  • Protected by Class H motor insulation and built-in amperage ( FLA ) and temperature overload protection
  • Include double silicon carbide mechanical seals in a separate oil-filled seal chamber and a heavy-duty lip seal
  • Stainless steel shaft and shaft sleeve saves on shaft wear due to abrasives and corrosion
