Submersible Pumps do not require cleaning.

Press Release Summary:
N-Pumps employ open-type self-cleaning impeller, and while operating, each leading edge passes across sharp stationary relief-groove. This action ensures that rags, stringy materials and solids are sheared, cleaned from impeller and pumped away. Pumps maintain high level of efficiency, even in fluids with high solids and fibrous content. Original Press Release:
Submersible Pumps Provide Sustained High Efficiency And Reduced Power Consumption
A new series of pumps introduced by ITT Flygt Corp. features an innovative hydraulic design, which ensures efficient, reliable, trouble-free pumping over long operating periods. Designated the "N-Pump" series, the units maintain a high level of pumping efficiency, even in fluids with high solids and fibrous content.
N-Pumps employ a unique open-type self cleaning impeller, and while operating, each leading edge of the rotating N-pump impeller passes across a sharp stationary relief-groove. This dynamic action ensures that rags, stringy materials and solids are sheared, cleaned from the impeller and pumped away. The risk of clogging is almost non-existant. As a result, the units maintain their operating efficiency over long operating periods.
Additionally, the pumps do not require labor-intensive periodic cleaning, a common requisite in other designs.
Increased efficiency translates into lower overall energy consumption, a significant factor in reducing the whole life cost of a pumping operation. Extensive field and laboratory tests have proved that the N-Pumps are superior to any other pump design in both efficienicy and clog resistance. Power savings as great as 45% have been achieved.
