Product Description

The model DDLFU submersible pumps are constructed of rugged cast iron with heavy duty, high efficiency motors suitable for industrial and municipal water and wastewater, drainage and sewage applications. The high efficiencies impeller make it possible to pass large solids up to 3 1/4″.

Applications

Industrial
Municipal
Water
Wastewater

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
