Submersible electric pump for draining sewage and wastewater, water from septic tanks, infiltration and rainwater and, in general, water loaded with solids in household applications.

It is designed using highly abrasion-resistant materials and it has a very compact, sturdy appearance, including a brass offset vortex impeller.

They have a reliable double mechanical closure system made of silicon carbide, ceramic and graphite with ceramic, to prevent malfunctions in the electric motor. They can be supplied with a level switch included in the single-phase versions to save as much time as possible during installation and to ensure optimum automatic operation. 

All parts in contact with water are coated with an anti-corrosion treatment.

Their oversized motor makes them excellent for prolonged, worry-free operation. It allows the passage of 32-mm solids. 

They are supplied with 10 m of cable and an external condenser.

They are equipped with 1 1/4" H axial outlet to minimise the installation space required.
