VORTEX 300

Submersible pump in cast-iron for sewage water, 2 poles, 2.2kW,
Max head: 13 m,
Max capacity: 700 L/min

Description

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 the VORTEX 300 can be used to pump sewage water and manure.

In case an electrical problem occurs, the reparation of the pump is extremely easy because the electric connections are positioned under the cover and completely isolated from the motor; so if some water enters into the pump from a cut in the cable the motor will be safe.

Use

The VORTEX 300 is usually installed into block of flats' cellars to drain the rain water or the domestic sewage water but 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.
