Kawamoto Pump Mfg. Co., Ltd.

Household

NR


Application

  • Pump up from reservoir
  • Booster from elevated tank
  • Lift up from shallow well
  • Other general water supply

Feature

  • Sanitary stainless. Stainless steel, bronze, and resin materials are adopted for major parts, thus preventing pump from rusting and red discolorment of water and highly durable.
  • The smallest model in industry. Realized the smallest household shallow well pump in industry. Compared with previous model (N3 250W) volume is reduced to 89% and weight is reduced to 93% (according to our survey of electric drive shallow well pump in 250
  • Constant pressure water supply. A stable water supply pressure is anticipated with both the pressure switch and the flow switch.
  • High reliability. It is realized excellent moisture resistance, with adoption of epoxy resin molded hybrid IC to the control circuits of automatic operation, and glass epoxy resin to the PC board, and the moisture resistant coating to the entire board. I
  • Silent operation design. silent operation design by improved pump cover (material change and opening shrinking)
  • Fulfilling protective functions. Temperature sensor is equipped to stop pump when abnormal water temperature rise for protection, as well as overload and restraint protection.
  • Adoption of ceramic heater. Using a long life and low power ceramic heater with thermostat for anti-freezing.
  • It is available either in suction lift up and inflow use by switching the fine sensor setting.
