The evacuation of wastewater and rainwater to the sewerage networks, the management of sanitation of buildings and populations, are now a fundamental chapter that must be addressed with great care, thus avoiding the danger to public health, if not eliminated quickly enough. The electric pumps of the ARS series are submersible units for the treatment of waste water, consisting of a hydraulic part and an electric motor. The hydraulic part has impellers of the following types: drainage, vortex, single-channel, multi-channel and shredders, which contributes to having a variety of solids passage between 6 and 105 mm. The suction and discharge flanges comply with EN 1092 (DIN 28605), from Ø40 to Ø300, and are drilled according to DIN 2501-PN10. The ARS electric pumps are groups of a great solidity and safety, thanks to their bearings and oversized shaft, probes of humidity and temperature (of series from 7,5 Cv), double mechanical seal, and oil chamber to lubricate the mechanical seals and to protect of the filtrations of water. Paint treatment by means of a double epoxy layer, reticulated with special polyamide for immersion and aggressive industrial environments. All groups have three-phase squirrel cage type electric motors. Power ratings range from 1.1 hp for drainage groups or crushers to 135 hp for multichannel groups. To select a submerged group, the following parameters must be taken into account: Manometric height Flow ph and electrical conductivity. Density and viscosity of the liquid to be pumped Application
