Tolerances according to UNI EN ISO 99: Regulation (EU) No 7/ The benchmark for most efficient water pumps is MEI,7. The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter. The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.

Flexible The option to choose between cast iron and bronze materias for the hydraulic parts in contact with the pumped liquid allows S and S series pumps to be selected for use with different types of liquids. New lantern bracket construction The lantern brackets incorporate a thrust bearing on the hydraulic side which guarantees the elimination of additional loads on the motor bearings. The flange is sized to be used with standard motors. Exclusive design n innovative, patented guard prevents contact with rotating parts, proving protection to the end user whilst allowing for inspection of the mechanical seal. Simplified motor maintenance The presence of the thrust bearing on the hydraulic side makes it easier to remove the motor, facilitating maintenance operations and eliminating the risks of damage to the hydraulic parts.
