MKNS - DEIGN FEATURES                                                                               1 Volute Casing : Top centerline discharge, lined with PFA-P. Minimum lining thickness of 6 mm, lining locked by multiple locking grooves. Outer body ductile iron, other materials like stainless steel available on request. 4 Shaft: Solid stainless steel with PFA-P lining.             2 Impeller : All impellers precision moulded in PFA-P, light in weight, closed construction. Closed impellers result in lower power requirements and higher efficiencies. 5 Magnetic Coupling : Powertransmitted to the pump by high quality samarium cobalt magnet. Product side wetted rotor is PFA-P lined.             3 Bearings : Impeller, Shaft and Magnetic Rotor are mounted on Sintered Silicon Carbide Bearings lubricated by process media via internal grooves. Bearings withstand brief dry running and lack of lubrication. 6 Isolation Shell : Made from PVDF / carbon fibre reinforced plastic (CFRP) with PFA-P inner shell is free from Eddy Currents thus prevents additional heating of the Pumping Media.
