This Centrifugal Electric pumps with rigid couplings offer a solid and reliable design which allows easy maintenance. Ideal for firefighting and irrigation, heating and air conditioning systems, heat recovery and pressurization groups.

Constructive Characteristics

Pumps are single-impeller, centrifugal type with rigid coupling, bare shaft pump. The coupling is obtained by means of a block with ball bearing on which the pump shaft is secured and integrated with a rigid coupling. The motor unit and the rotating part of the pump can be taken away without removing the pump body from the system piping.

  • Pump body with dimension and performances according to EN 733 rules, closed impeller dynamically balanced and with balance holes for the balancing of the axial thrust.
  • Shaft completely in stainless steel, greased ball bearings.
  • Motor: asynchronous with 4 poles and with external ventilation.
  • Protection: IP55.
  • Insulation: class F.
  • Frequency: 60 Hz.

Applications

  • Recycling plants.
  • Heating, air conditioning.
  • Heat recovery, plants of water supply procurement.
  • Pressurizing units.
  • Firefighting.
  • Irrigation.
