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.
