Kawamoto Pump Mfg. Co., Ltd.




  • Household
  • Industrial
  • Small regional drinking water
  • Other general water supply


  • Clean water supply with stainless: Rust-less stainless steel adopted to Pump, motor and pipes in automatic operation unit provides clean water for long time.
  • Energy saving: Optimally controlling the pump speed according to the changes in working water rate with the VFD realize water supply with keen energy saving.
  • Maximum twice capacity: Compare to Jet pump, water capacity becomes to twice in maximum.
  • Conformable water supply with constant pressure: Supplied water pressure is always stable with constant pressure control by VFD without being affected by fluctuations in the well water level. Also, when installing in a shallow well, pressure reducing valv
  • Tough against sand: Adopting Stainless steel, Abrasion resistant resin, Rubber, and SiC bearings brings toughness to sand under sever usage situation. Moreover, equipped Dry-run protection enhance robustness.
  • Lightning resistant: High reliability to lightning due to twice surge resistance compare to our conventional model. In addition to that, quiet operation sound because of under water installation.
  • Soft start: VFD controlled soft start give less impact to power source (sudden start causes voltage drop), and well (sudden start swings pump).
