VORTEX 75

Submersible pump in cast-iron for sewage water, 2 poles, 0.55kW,
Max head: 8 m,
Max capacity: 225 L/min

 

Description

Small 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 and the top quality oil bathed motor the VORTEX 75 can be used also to pump sewage water and manure. In the model VORTEX 75 the capacitor is always positioned in an external control box to reduce the dimensions of the pump permitting the installation in really small pits.

Use

The VORTEX 75 is usually installed into houses' cellars to drain the rain water or the domestic sewage water but it is also used in farms to pump out the dirty waters of the stables containing manure and solid parts. This model cannot be used to pump water containing stones.
