Close Coupled Centrifugal Pumpswith flanged connections NM EI
Pumps with frequency converter
The NM EI pumps are available with power from 0,55 kW up to 22 kW, the pumps are equipped with I-MAT installedon board which allows to realize a variable-speed system extremely compact and efficient, ideal in applications of watersupply and in the distribution of hot and cold water. The pump is equipped with transducers suitable for operation and is already programmed at the factory.
Advantages- Energy saving- Compact design- Easy to use- Programmable to suit the system requirements- Reliability
CostructionThe system comprises of:- Pump- Induction motor- I-MAT Frequency converter- Motor adapter for the motor mounting of the frequency converter- Connection cable between frequency converter and induction motor- Transducers
Main featuresRated motor power output from 0,55 kW to 22 kWControl range from 1750 to 2900 rpm (2-pole) Protection against dry runningProtection against operations with closed valve portsProtection against system leakagesProtection against overcurrent in the motorProtection agains overvoltage and undervoltage of the power supplyProtection against current unbalances between phases
Constant pressure mode with pressure transducer
In this mode, the system maintains the preset pressure when the flow required bythe installation changes.
Proportional pressure mode with pressure transducer
In this mode the system changes the working pressure according to the requiredflow rate.
Constant flow mode with flow meter
In this mode the system maintains a constant flow rate value in a point of the instal-lation according to the required pressure.
Fixed speed mode with setting of the speed preferential rotation.
In this mode, by changing the working frequency, you may choose any operationalcurve included within the working range.
Constant temperature modewith temperature transducer
In this mode the system keeps the temperature constant inside a system by chan-ging the speed of the pump.

Features
Close Coupled Centrifugal Pumpswith flanged connections NM, NMS
NMS
NM
Cutting edge hydraulicsThe geometry of the impeller and the pump casing areoptimized to achieve maximum efficiency and the bestsuction capability.
FlexibleThe option to choose between cast iron and bronze mate-rias for the hydraulic parts in contact with the pumpedliquid allows NM series pumps to be selected for use withdifferent 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.
ReliableThe 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.
