Feature

Evaluated item of "Submersible motor pump (for dirty water: bore 40 or 50mm, for miscellaneous waste: 50mm)" by (C) Public Buildings Association., Ltd.
Starting/stopping water levels are adjustable in L and LN types.
Light and easy to handle, due to resinified pump parts and motor with stainless steel frame.
Adopting Resin & Stainless materials brings long machine life with corrosion resistance.
Very robust with limit load characteristics in pump and built-in auto cut (0.15S and 0.25S model adopt Klixon) in motor.
As well as excellent performance to pass foreign objects because of vortex structure, furthermore, high water pumping performance.
Strainer is quick detachable type for easy cleaning and maintenance.
Double mechanical seal prevents water immersion into motor.
Built-in automatic type (-L) and automatic alternative type (-LN) with float switch are available.
Automatic/parallel operation type works automatic alternate & parallel operation without control panel when combines with automatic operation type. When water level will increase, they operate parallel automatically. Just in case of one pump malfunction,
