Enbloc centrifugal electric pumps with coupling designed for a wide range of applications such as:
  • Water supply.
  • 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.

    Particularly versatile thanks to the use of the HYDRODRIVER, it offers performance features that automatically adapt to various system requirements whilst keeping differential pressures constant. 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. Cast iron impeller, encased and dynamically balanced with compensation of the axial thrust by means of balancing holes, operating (on request) with interchangeable consumable rings. AISI 304 stainless steel pump shaft. Seal: standardised mechanical seal made to DIN 24960 in carbon / carborundum with O’ rings in EPDM. Closed, asynchronous motor with external ventilation, construction type B3/B5, 2 poles for NKP-GE and 4 poles for NKM-GE. Rotor mounted on oversized ball bearings to ensure silent running and long life. We recommend using overload protection for the motor, in accordance with current norms. In the case of liquids denser than water, the motors must be proportionally more powerful.
