Key Features

  • Heavy-duty, high efficiency, air-filled motor – operates cooler with higher efficiencies, resulting in reduced operating costs.
  • Watertight cable entry system – protects against moisture and capillary action; reduces maintenance costs
  • Self cooling jacket
  • 60,000 hour single and double row thrust bearings – long dependable operation, lowers maintenance costs
  • High-efficiency impellers – handle stringy, fibrous material with the ability to pass large solids and prevent clogging; impellers are optimized for hydraulic coverage lowering operating costs
  • Double mechanical seals – operate in an oil bath providing longer service life and lower maintenance costs
  • Stainless steel shaft – high tensile strength and corrosion resistance
  • Replaceable wear components – maintain working clearances while reducing casing and volute costs
