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 bronzematerias for the hydraulic parts in contact with the pum-ped liquid allows NM and NM4 series pumps to be selec-ted for use 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.

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 bronzematerias for the hydraulic parts in contact with the pum-ped liquid allows NMS and NMS4 series pumps to beselected for use with different types of liquids.

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.

ConstructionClose-coupled centrifugal pumps; electric motor with extended shaftdirectly connected to the pump up to 15 kW, new bracket construc-tion for standard motors (Stub-shaft construction) from 18,5 to 75kW with integrated thrust bearing. Pump casing with axial suctionand radial delivery on top, main dimensions and performance accor-ding to EN 733 with additional sizes for completion.NM(S)4: version with pump casing and lanter bracket in cast iron.B-NM(S)4: version with pump casing and lanter bracket/casing

Features


NM4

Cutting edge hydraulicsThe geometry of the impeller and the pump casing are optimized to achieve maximum efficiencyand the best suction capability.

FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contactwith the pumped liquid allows NM and NM4 series pumps to be selected for use with differenttypes of liquids.

Compact DesignThe compact design allows for easy installtion even in confined spaces.

Exclusive designAn innovative, patented guard prevents contact with rotating parts, proving protection to the enduser whilst allowing for inspection of the mechanical seal.

ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providing high reliabi-lity under all operating conditions.

NMS4

Cutting edge hydraulicsThe geometry of the impeller and the pump casing are optimized to achieve maximum efficiency andthe best suction capability.

FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contact withthe pumped liquid allows NMS and NMS4 series pumps to be selected for use with different types ofliquids.

New lantern bracket constructionThe lantern brackets incorporate a thrust bearing on the hydraulic side which guarantees the elimina-tion of additional loads on the motor bearings. The flange is sized to be used with standard motorsB35.

Exclusive designAn innovative, patented guard prevents contact with rotating parts, proving protection to the end userwhilst allowing for inspection of the mechanical seal.

Simplified motor maintenanceThe presence of the thrust bearing on the hydraulic side makes it easier to remove the motor, facilita-ting maintenance operations and eliminating the risks of damage to the hydraulic parts.

Features

Cutting edge hydraulicsThe geometry of the impeller and the pump casing are optimized to achieve maximum efficiencyand the best suction capability.

FlexibilityThe option to choose between cast iron and bronze materias for the hydraulic parts in contactwith the pumped liquid allows N-N4 series pumps to be selected for use with different types ofliquids.

RobustnessThe mechanical structure of the hydraulic parts in contact with the pumped liquid are dimensio-ned to guarantee the maximum resistence to mechanical stress. Also the casing cover is provi-ded with wings that prevent turbulence in the area of the mechanical sea, increasing the reliabi-lity.

ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providing high reliabilityunder all operating conditions.
