Submersible Axial, Mixed Flow Propeller Pump


The model DSZ3 submersible pumps are constructed of rugged cast iron with heavy-duty, high-efficiency motors suitable for moving high volumes of water at low heads typically evident in industrial and municipal water and wastewater installations such as storm water and flood control applications. The large, submersible non-clog pump has an axial flow impeller design.

Key Features

  • Heavy-duty, air-filled Class F insulated motor – operates cooler with higher efficiencies
  • Watertight cable entry system – protects against moisture and capillary action and reduces maintenance costs
  • Self-cooling jacket – provides high reliability and effectively dissipates heat
  • Double and triple row lubricated thrust bearings – L-10 life of 100,000 hours equates to long, dependable operation and lower maintenance costs
  • Float type leakage detector – provides early warning of mechanical seal failure avoiding costly motor repairs
  • Cartridge type, duplex mechanical sealsassembled in tandem arrangement leading to high reliability and easy maintenance
  • High-efficiency, axial flow impellers – are able to pass large diameter solids with high outputs, preventing clogging and lower operating costs
  • Replaceable case liner ring – maintains working clearances while reducing casing costs
