NKM-GE NKP-GE ENBLOC ELECTRONIC CENTRIFUGAL PUMPS CONDITIONING, IRRIGATION, INDUSTRIAL APLLICATION silent and durable operation. Speed of rotation: 1450 - 2900 1/min. Operating range: from 1 a 450 m3/h head up to 72 metri. Liquid temp. range: from -10°C to +140°C. Pumped liquid: clean, free from solids or abrasive substances, not viscous, not aggressive, not crystallised and chemically neutral and close to the characteristics of water. Installation: normally horizontal or vertical provided the motor is always above the pump. Max. ambient temperature: +40°C. Maximum operating pressure: 16 bar - 1600 kPa (for DN 200 max. 10 bar). Protection rating: IP 55. Insulation class: F. Flanging: PN 16 DIN 2533. Special versions on request: Pumps for liquids other than water. Other voltages and/or frequencies. Inverter modulation with 0-10V signal Enbloc electric centrifugal pumps with coupling, designed for a wide range of applications such as: • Circulation of hot water for heating. • Circulation of cold water for air conditioning. • Circulation of cold water for cooling. Highly versatile pumps thanks to the use of the MCE/C inverter, to guarantee performance able to automatically adapt to the various system requirements, while maintaining constant differential pressure. Spiral singlestage body in cast iron according to DIN-EN 733 (ex DIN 24255), cast iron support, flanges according to DIN 2533 and DIN 2532 for DN 200. Cast iron impeller, sealed and dynamically balanced with compensation of the axial thrust via balancing holes, operating (on request) on interchangeable wear rings. Pump shaft in AISI 304 stainless steel. Seal: standardised mechanical seal according to DIN 24960 in carbon/silicon carbide with O-rings in EPDM. Asynchronous, closed motor cooled by external ventilation, construction design B3/B5, 2-pole for NKPGE and 4-pole for NKM-GE.
