  • PRODUCT DESCRIPTION
Enbloc centrifugal electric pumps with integral shaft 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

    Pump construction characteristics Single-stage, cast iron spiral body made to DIN-EN 733 (formerly DIN 24255), cast iron support, flanges in accordance with DIN 2533. 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. Motor construction characteristics: closed, asynchronous motor with external ventilation, 2 poles for NKP and 4 poles for NKM. 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.
