Kawamoto Pump Mfg. Co., Ltd.

Sea water

KZB


Application

  • For processing plant's cleaning and various sea water supply

Feature

  • Industry's first automatic packaged seawater booting unit: It is the industry's first sea water automatic packaged booster pump with unique how-how based on our actual achievement of sea water use.
  • Excellent corrosion resistance: Composed of nylon coated major parts contacting liquid, such as the casing.
  • Other parts contacting liquid are made from SUS316 and resins, and are ideal for pumping sea water thanks to their superior corrosion resistance.
  • It shows excellent corrosion resistance to organic matter corrosion with our original nylon coating structure under conditions where fresh seawater does not come in.
  • Constant pressure water supply: An operation method with a optical pressure sensor and flow sensor has been adopted, so a stable water supply pressure can be achieved, with very little pressure fluctuation during water supply.
  • High reliability: Adopting a special design which uses the optimal materials for resistance to sea water in the pressure sensor and flow sensor, which are the key component for automatic operation.
  • Resistant to corrosion and clogging from foreign objects, and provides a stable water supply.
  • In addition to that, Control panel is contact-less type, thus, long machine life without worn out of magnetic contactor. (excluding sole operation model) * periodical replacement is necessary. (Pressure sensor, Flow sensor, Check valve disk, Flexible pipe
