Application

  • Automatic water supply from shallow & deep well
  • Pump up from reservoir
  • Booster from elevated tank
  • Other general water supply

Feature

  • Clean water supply: Adopting Casted stainless steel for Pump casing and rust-less materials such as stainless, resin, or rubber for other major parts enable to clean water supply for long period. Complied with Japanese drinking water standard.
  • Energy saving: Adopting Permanent magnetic motor brings high energy saving with optimal operation control.
  • Constant pressure water supply: By optimally controlling the pump speed according to the changes in working water rate with the inverter, constant pressure water supply with little fluctuation is possible regardless of fluctuation in the well water level.
  • Dual use for shallow & deep well: By selecting jet parts, it is available both for shallow well and deep well. Moreover, adopting inverter makes it possible as hertz free operation. * Adoptable to conventional jet parts.
  • Compact and lightweight (in case of independent operation): Compact design realizes further compactness and weight reduction, achieving compactness of the same size up to 750 W at 250 W size or less of conventional products. Moreover, the mass is also abo
  • Plenty of protective functions: As well as overload/restraint protection, a freezing prevention function without heater, which forcibly operates the pump by temperature detection sensor is equipped.
  • Noise & harmonic suppression: Equipped noise filter and reactor suppress noise and harmonic.
  • Soft start: Inverter reduces starting current and impact to power source, may causes voltage drop.
