Kawamoto Pump Mfg. Co., Ltd.

Submersible(drainage)

DUG2/DU2/DU4/DUM2


Application

  • General civil engineering and construction work.
  • Drainage for rain water and sump
  • Manhole and pit drainage

Feature

  • Adopting new developed small & high torque motor, and urethan rubber for Impeller so that is strength to lubrication, it performs excellent pump characteristics.
  • Aluminum die casted motor frame and adopting rubber materials brings weight and size down.
  • Vortex structure relieves Impeller lock from sand, and easy disassemble and assemble.
  • Built in auto-cut prevents motor from burn.
