- The benchmark for most efficient water pumps is MEI ≥ 0,70.- 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.

Cutting edge hydraulicsThe geometry of the impeller and the pump casing areoptimized to achieve maximum efficiency and the bestsuction capability.

FlexibilityThe option to choose between cast iron and bronze mate-rias for the hydraulic parts in contact with the pumpedliquid allows NM and NM4 series pumps to be selected foruse with different types of liquids.

Compact DesignThe compact design allows for easy installtion even inconfined spaces.

Exclusive designAn innovative, patented guard prevents contact with rota-ting parts, proving protection to the end user whilstallowing for inspection of the mechanical seal.

ReliabilityThe bearing and shaft are designed to ensure the reduc-tion of the stress, providing high reliability under all ope-rating conditions.

New lantern bracket constructionThe lantern brackets incorporate a thrust bearing on thehydraulic side which guarantees the elimination of addi-tional loads on the motor bearings. The flange is sized tobe used with standard motors B35.

Exclusive designAn innovative, patented guard prevents contact with rota-ting parts, proving protection to the end user whilstallowing for inspection of the mechanical seal.

Simplified motor maintenanceThe presence of the thrust bearing on the hydraulic sidemakes it easier to remove the motor, facilitating mainte-nance operations and eliminating the risks of damage tothe hydraulic parts.
