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.

They are provided with DIN flanges on the DN50 delivery side and they are very versatile, such that they can be installed with 90º elbows or with automatic anchorage systems. This makes them sturdy pumps for difficult, demanding applications. 

They have a silicon carbide and ceramic mechanical double closure system to prevent malfunctions of the electric motor. 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 40-mm solids. 

ATEX (ATEX II 2G d II B T4) versions are manufactured to order.
