Submersible pump in cast-iron for sewage water, 2 poles, 4kW,
Max head: 23 m,
Max capacity: 1050 L/min



Pump in cast-iron with "vortex" impeller. When the impeller turns, it creates a vortex pushing the water through the pump body. As the impeller is positioned in the upper part of the pump body it permits a wide free passage for the solid parts contained into the water. Thanks to its heavy duty construction, the double indipendent mechanical seals and the top quality oil bathed motor this model can be used to pump sewage water and manure.


The VORTEX 550 E is usually installed into block of flats' cellars to drain the rain water or the domestic sewage water in particular when a good head is required. This model is also often used in farms to pump out the manure of the stables, in industrial plants, in sewage water treatment plants, etc. This model cannot be used to pump water containing stones.
