Description
Technical Data
This SAER 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.
MG4 With Motor (Motor replacing Capability)
Applications
- Recycling plants.
- Heating.
- Air conditioning.
- Heat recovery.
- Plants of water supply procurement.
- Pressurizing units.
- Firefighting.
- Irrigation.
Constructive Characteristics
MG4 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.
Hydraulics
- Pump body in Cast iron, 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, flanges (UNI EN 1092-2): up to DN 150: PN16, from DN 200: PN10.
- Motor: asynchronous with 4 poles and with external ventilation.
- Protection: IP55.
- Insulation: class F.
- Frequency: 60 Hz.
