In-line PumpsNR EI, NR4 EIPumps with frequency converter
The NR EI, NR4 EI, pumps are available with power from 0,25 kW up to 18,5 kW, the pumps are equipped with I-MATinstalled on board which allows to realize a variable-speed system extremely compact and efficient, ideal in applications ofwater supply 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 0,25 kW to 18,5 kWControl range from 1750 to 2900 rpm (2-pole) Control range from 870 to 1450 rpm (4-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.
