Close Coupled Centrifugal Pumpswith threaded portsNM, NMDNM, NMD
1ConstructionClose-coupled, centrifugal pumps; electric motor withextended shaft directly connected to the pump.NM: single-impellerNMD: with two back-to-back impellers (with axial thrust balancing).Connections: threaded ports ISO 228/1 (BS 2779).NM, NMD: version with pump casing and lanter bracket in cast iron.B-NM, B-NMD: version with pump casing and lanter bracket in bronze.
(the pumps are supplied fully painted).
Applications- For clean liquids without abrasives, which are non-aggressive
for the pump materials ( solids content up to 0.2%).- For water supply.- For heating, air-conditioning, cooling and circulation plants.- For civil and industrial applications.- For fire fighting applications. - For irrigation.
Operating conditionsLiquid temperature from -10 °C to +90 °C.Ambient temperature up to 40° C.Total suction lift up to 7 m.Maximum permissible working pressure up to 10 bar(16 bar for pumps NMD 25/190; NMD 32/210; NMD 40/180).Continuous duty.
Motor2-pole induction motor, 50 Hz (n = 2900 rpm).NM, NMD: three-phase 230/400 V ± 10% up to 3 kW;
400/690 V ± 10% from 4 to 9,2 kW;NMM, NMDM: single-phase 230 V ± 10%, with thermal protector.Insulation class F. Protection IP 54.Classification scheme IE2 for three-phase motors from 0,75 kW.Constructed in accordance with EN 60034-1; EN 60034-30.
EN 60335-1, EN 60335-2-41.
Special features on request- Other voltages. - Frequency 60 Hz (as per 60 Hz data sheet).- Protection IP 55. - Special mechanical seal- Higher or lower liquid or ambient temperatures.- Motor suitable operation with frequency converter.

Compact DesignThe compact design allows for easy installtion even in confined spaces.
RobustnessThe mechanical structure of the hydraulic parts in contact with the pumped liquid aredimensioned to guarantee the maximum resistence to mechanical stress.
A unique designThe lantern bracket design prevents contact with the pumps rotating parts, providingprotection to the end user whilst allowing for inspection of the mechanical seal.
ReliabilityThe bearing and shaft are designed to ensure the reduction of the stress, providinghigh reliability under all operating conditions.
