NKM-GE / NKP-GE MCE-C FOR CIRCULATION SYSTEMS MCE-P FOR PRESSURIZATION SYSTEMS TECHNICAL DATA Rotation speed: 1450 - 2900 1/min. Operating range: from 1 to 470 m3/h with head up to 72 metres. Liquid temperature range: from -10 °C to +140 °C (MCE/C) from -10 °C to +80 °C (MCE/P) Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water. Installation: normally in horizontal or vertical position, provided that the motor is always above the pump. Maximum ambient temperature: +40 °C. Maximum operating pressure: 16 bar - 1600 kPa (for DN 200 max 10 bar). Insulation class: F. Flanging: PN 16 DIN 2533. Standardised centrifugal electronic pumps on base with elastic coupling, designed for a wide range of applications, such as: MCE/C: Circulation of the hot water of the heating system, of the cold water of the air conditioning and refrigeration systems. MCE/P: Pressure increase, supply of drinking water and sprinkler and watering systems. CONSTRUCTION FEATURES OF THE PUMP Cast iron single stage spiral body complying with DIN-EN 733 (formerly DIN 24255), cast iron support, flanges complying with DIN 2533, and DIN 2532 for DN 200. Cast iron impeller, closed and dynamically balanced, with compensation of the axial thrust through balancing holes, operation on interchangeable wear rings (on request). AISI 304 stainless steel pump shaft. Seal device: standardised mechanical seal according to DIN 24960 in carbon/silicon carbide with EPDM OR rings. CONSTRUCTION FEATURES OF THE MOTOR Closed asynchronous type motor with external ventilation, B3/B5 construction, two poles for NKP-GE and four poles for NKM-GE. Rotor running on ball bearings, largely oversized to ensure low noise and durability. For liquids with densities higher than water, motors with proportionally higher powers are required. Construction according to CEI 2-3. Controlled by MCE inverter. Protection class: IP 55 Standard single-phase voltage: 1x230 V / 50-60 Hz Special version on request: three-phase 3x400 V / 50 Hz or three-phase 3x460 V / 60 Hz Standard three-phase voltage: 3x400 V / 50 Hz Special version on request: 3x460 V / 60 Hz DAB PUMPS reserves the right to make modifications without notice. CENTRIFUGAL ELECTRONIC PUMPS STANDARDISED MONOBLOC CENTRIFUGAL ELECTRIC PUMPS WITH INVERT

CENTRIFUGAL ELECTRONIC PUMPS NKM-GE / NKP-GE STANDARDISED MONOBLOC CENTRIFUGAL ELECTRIC PUMPS WITH INVERTER MCE/C INVERTERCONSTRUCTION FEATURES OF THE ELECTRONICS: MCE/C INVERTER MCE/C inverters have been designed for managing circulation pumps. By allowing a simple adjustment of the differential pressure, they give the possibility of adjusting the performance of the circulation pump to the actual system requirements. They are fitted on the fan cover of the motor. This makes the installation of the pump with MCE/C particularly easy and quick. The protection class of the MCE/C is IP55. The easy...

NKM-GE / NKP-GE MCE/P INVERTER CONSTRUCTION FEATURES OF THE ELECTRONICS: MCE/P INVERTER The inverter continuously adjusts the rotation speed of the electric pump, keeping the pressure constant, even when the flow rate varies. The other electric pumps, also with variable speed, are activated in cascade after the first one has reached maximum speed. Through modulation, they compensate the pressure fluctuations of the system. For every operating cycle, it is possible to switch the restart to a different pump, therefore ensuring even use of all electric pumps. It is possible to set operation times...
