4" submerged sump pump equipped with a special system of floating impellers with front shim, which allows it to operate even in particularly heavy conditions without blocking and which gives the electric pump a low axial load.
It is a very quiet product that boasts high hydraulic efficiency that can be coupled with motors in water bath or oil bath.
It can also be used in a horizontal position.
