Submersible electric pumps for draining sewage, wastewater, water from septic tanks, infiltration and rainwater and, generally, water with a solid load.

They can be used in household and residential, industrial and agricultural environments and in general construction.  

They have been designed using highly abrasion-resistant materials, making them look very compact and sturdy. On the delivery side, they are fitted with a DN65 DIN flange and are very versatile, allowing them to be installed with 90º elbows or with an automatic anchorage system. This makes them sturdy pumps for difficult, demanding applications. 

They have a silicon carbide and ceramic mechanical seal system to prevent malfunctions of 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. 

All parts in contact with water are coated with an anti-corrosion treatment. Their oversized motor makes them excellent for prolonged, worry-free operation.

They can operate partially submerged although, for optimum operation, it is advisable to make sure they are submerged.

Passage of 60 mm solids.
