The magnetic drive centrifugal pumps PD series, made by
the Japanese company SANSO, are plastic moulded pumps: the BLDC motors allow these
pumps to have various advantages compared with DC brushes or AC pumps:
- Better efficiency, due to the DC motor
- Better performances due to the higher totation speed
- Less pump weight and more compact design
- Longer life due to the static motor
- Less maintenance
- Very simple and inexpensive installation, due to the BL drive supplied onboard the pump
or on separate electronic board
