Kawamoto Pump Mfg. Co., Ltd.

Sea water

NFZ


Application

  • A variety of seawater Intake and supply.
  • General service water in ship
  • Other general water supply

Feature

  • Excellent corrosion-resistant package pump with casing and other main parts contacting liquid made of stainless steel and resin. Other parts contacting liquid also adopt dedicated design products that use optimum materials for sea water resistance, making
  • Constant discharge pressure: 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.
  • Energy saving operation: Adopting Low noise type VFD and high efficiency motor, and enhancing pump efficiency realize energy saving operation with quiet operation sound.
  • Standard built in noise filter and reactor suppress noise and harmonics.
  • Soft start: Inverter smooths starting current. This also suppresses bad effect to power source like as voltage drop.
  • Compact and less weight design.
