Impeller pump MPP201

waterwith electric motormagnetic-drive

Operating principle The distinctive feature of magnetic drive pump is the absence of a connection between motor and pump. The rotation of the impeller is obtained by the magnetic force between two magnets : one is coupled to the motor, the other drives the impeller. This construction guaranties the highest reliability and avoids any leackage, so maintenance interventions are reduced and simplified. The materials used are: • Polypropylene and PVDF for plastic components. • Ceramics (Al2 O3 99,7%) for shaft and thrust ring. • Rulon for bearings • EPDM or Viton for the O-ring. DIRECTIVES: • The pump should never run dry. • Dirty liquids and crystals reduce the life of the bearings. • The ambient temperature should be between 0 and 40 °C. • Flame proof motors should be used in explosive atmospheres. • The liquid should not crystallize in the pump. • The maximum temperature of the pumped liquid should be: 70 °C (for PP) 95 °C (for PVDF)
