Enbloc, centrifugal electric pumps with coupling designed for a wide range ofapplications such as:• supplying water.• circulation of hot water for central heating.• circulation of cold water for air conditioning and refrigerating.• transfer of liquids in agriculture, horticulture and industries.• implementation of pumping systems.Single-stage, cast iron spiral body made to DIN-EN 733 (formerly DIN 24255),cast iron support, flanges in accordance with DIN 2533 and DIN 2532 for DN 200.Impeller in cast iron, encased and dynamically balanced with compensation of theaxial thrust by means of balancing holes, operating (on request) with interchan-geable consumable rings. AISI 304 stainless steel pump shaft. Seal: standardisedmechanical seal made to DIN 24960 in carbon/carborundum with O’ rings inEPDM. Closed, asynchronous motor with external ventilation, construction typeB3/B5, 2 poles for NKP and 4 poles for NKM.We recommend using overload protection for the motor, in accordance with cur-

Speed of rotation: 1450 - 2900 1/min.Operating range: from 1 to 500 m3/h with a head of up to 100 metres.Pumped liquid: clean, without solid or abrasive substances, not viscous, notaggressive, not crystallised and chemically neutral, close to water characteristics.Liquid temperature range: from -10°C to +140°C.Maximum ambient temperature: +40°C.Maximum working pressure: 16 bar - 1600 kPa (for DN 200 max. 10 bar).Flanging: PN 16 DIN 2533 - PN 10 DIN 2532 for DN 200Installation: normally horizontal or vertical provided the motor is always abovethe pump.Special versions on request: pumps for liquids other than water.Other voltages and/or frequencies.
