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.
