6'/8'' SUBMERSIBLE ELECTRIC RADIAL PUMPS - 140 AND 180 RSX SERIES IN MICROCAST STAINLESS STEEL EN 1.4301
The RSX range of radial pumps are made entirely of microcast stainless steel EN 1.4301 (AISI304) and represent the most advanced and powerful solution in the RX range. The radial solution, with a particularly small axial footprint, allows a high number of stages to be used, giving very high heads for the same diameter.
The diffuser, thanks to the extended blade system up to the impeller outlet, allows the water to follow a forced trajectory, with a consequent increase in performance and hydraulic efficiency. The stage consists of Impeller, diffuser, cone and ring nut, intermediate bush, wear ring, O-ring.
In this type of pump, the impellers are secured to the pump shaft by means of the cone and ring nut, thus avoiding key cutting and the associated weakening of the shaft. The diffuser casings are interlocked by means of a threading system, thus eliminating tie rods that can expand and/or contract during operation, causing possible water leakage between the stages.
