Application

• Sewage and sump drainage
• Sewage including solid and drainage facility for office building, hotel, factory, hospital, condominium, and etc.

Feature

• Excellent ability to pass foreign objects without entangling with adoption of circle figure casing and flat blade impeller. (Can discharge spherical solids with a diameter which equals to the bore size.)
• Excellent ability to pass foreign objects and superior pumping performance with our original casing structure.
• Vortex impeller decreases worn out caused by sand etc., and prevents startup failure due to rusted impellers.
• Equipped with a motor with built-in auto-cut (7.5kW or less) to prevent motor burnout.
• Motor with output of 11kW or above can detect abnormal temperature rise of the motor coil as an external signal. (Implement a circuit in the control panel when use it as a protection devise)
• Two types available: flange type and pedestal support type for easy maintenance and inspection.
• Built-in automatic type ("L") and automatic alternative type ("LN") with float switch are available.
• Protection circuit for electric parts is equipped on the models with float switches.
• Evaluated item of by (C) Public Buildings Association., Ltd. in Japan.
