Applications SKA self-priming rotodynamic, pumps with side ring channel and open impeller, serve to pump liquids within the corrosion resistance limits of materials used for their construction. Liquids of a temperature up to 110oC, discharged liquid density up to 1 300 kg/m3 and viscosity up to 150 mm2/s contaminated with solid particles up to 0.5 mm in trace amounts can be pumped. Pumps can cooperate with 50 Hz or 60 Hz motors. SKA pumps can be used in: waterwork systems, , individual farms, industry.
