Kawamoto Submersible Pump

WUO

Product code: WUO

Application

Drainage of sump or sewage
Pit drainage
Sump drainage
Septic tank drainage

Feature

Light weight and easy handling sewage submersible pump.
Stainless steel made frame motor and plastic parts increase operating life.
Starting/stopping water levels are adjustable in L and LN types.
Uses glass fiber reinforced plastic for the impeller and casing, and equipped with a motor with built-in auto-cut (Klixon in 0.15S and 0.25S ) for stable operation.
As well as excellent performance to pass foreign objects because of vortex type, furthermore, high water pumping performance.
Double mechanical seal prevents water immersion into motor.
Built-in automatic type ("L") and automatic alternative type ("LN") with float switch are available.
Automatic alternate/parallel operation is possible without control panel by using automatic alternate type and automatic type in combination. in addition to that, it will carry out parallel operation in abnormal water level rise just in case.
