SERIES 140 RHX

The radial pumps in the RHX range are made entirely of microcast AISI 304 stainless steel and represent the most advanced and high-performance solution in the radial range. The radial solution, which has a very small footprint in the axial direction, allows the use of a high number of stages, with the consequence of obtaining very high heads with the same diameter. The diffuser, thanks to the extended blade system up to the outlet of the impeller, allows the water to follow a compulsory 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 fixed to the pump shaft by the cone and ring nut, thus avoiding key cutting and the associated weakening of the shaft. The diffuser body is locked to each other by n° 8 captive screws.
