Salvatore - Model RD (RDB-RDL-RDM) - Centrifugal Pumps - Datasheet

This range includes centrifugal pumps with closed impeller [RD] type and open impeller [RG] type, both unified with the hydraulic part according to the EN 22858 chemical rule and the mechanical one according to EN 25199 , which defines the max. shaft deflection, mechanical resistance and ball bearings’ minimum life. The main aspects of this series are mechanical parts modularity, interchangeability, wide sealing systems’ choice, but also hydraulic design interchangeability (open and closed impellers mounted on the same pump casing) and low NPSH values. This allows to use these pumps from the easiest applications with aggressive liquids to the most difficult applications with suspended solids, high temperatures, high viscosity and specific gravity. Max. operating pressure is 16BAR, but it can reach 20 BAR, when used for not aggressive liquids.
