VORTEX 550-750

Professional submersible pumps in cast-iron for heavy sewage water, 4 poles, from 4kW to 5.5kW,
Max head: 18 m,
Max capacity: 3.000 L/min

 

Description

Pumps in cast-iron with single-channel impeller. This kind of impeller grants a good free passage for the solid and fibrous parts contained into the water but it gives also an higher flow and head than the "vortex" impeller. These models with an heavy duty construction, double mechanical seals and 1450 rpm motor can be used to pump heavy sewage water.

Use

The VORTEX 550 and VORTEX 750 are usually installed into big block of flats' cellars to drain the dirty water or in public sewage water nets. These models are also often used in farms to pump out the manure of the stables, in industrial plants, in sewage water treatment plants, in sludges treatment plants, etc. These models cannot be used to pump water containing stones.

Operation conditions

Max liquid temperature: 50 °C (122 °F)

pH: 6-10

Max density < 1100 kg/m³

Max immersion depth: 20m
