CORROSION AND WEAR OF WASTEWATER PUMPING SYSTEMS

The submersible pumps are submerged in the fluid that must be pumped, this type of pump is capable to push out large volumes of water. The watertight subassembly of this equipment includes a variable power engine that can be used for various household applications or industrial purposes. Wastewater transported by pumps corrodes and wear the transport system. The materials used for the construction of these pumps must withstand the acidity of the water, capitation phenomenon, the wear caused by the particles in the suspension and maintain their operating properties. The paper presents an analysis of the wear and corrosioneffects on the wastewater pumps and an analysis of the pump impeller material.
