DDLFU - Ebara Pump

Dry pit cast iron wastewater, sewage pump

Model DDLFU

The model DDLFU submersible pumps are constructed of cast iron with heavy-duty motors and high-efficiency impellers that make it possible to pass slurries, sludge, sewage and large solids up to 3 1/4″. The DDLFU is suitable for various dry pit applications including industrial and municipal water and wastewater, lift stations and treatment facilities.

Key Features

  • Heavy-duty, high-efficiency, air filled, Class H insulated motor – rated for 356°F with a 1.15 service factor dissipates heat easily; thermal protection in each phase of windings protects; operates cooler with higher efficiencies; longer service life with lower operating costs
  • Watertight cable entry system – protects against moisture and capillary action; reduces maintenance costs
  • Self-cooling jacket - eliminates the need for external pumping devices or special heat transfer fluids; offers simplicity and high reliability by effectively dissipating heat in dry pit applications only
  • 60,000 hour single and double row thrust bearings – long dependable operation, lowers maintenance costs
  • High-efficiency impellers – ability to pass large solids with high outputs prevent clogging and handles stringy material better, 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

Applications

  • Industrial
  • Municipal
  • Water supply
  • Wastewater
  • Storm water, flood control
  • Sewage
  • Lift stations
