Speroni CUTTY Industrial Submersible Sewage Pumps

The Speroni CUTTY series grinder pumps are of cast iron construction. They are used in sewage stations and for servicing individual, or groups, of houses where drainage by gravity is not possible. They are ideally suited to applications where effluent is required to be pumped over a long distance, through a small bore pipe. They have cast iron impellers and cutting devices constructed in 304 stainless steel which are designed to pump and pulverise sewage, soft solids or shreddable fibres. The high heads produced, with only limited horsepower motors, also make them suitable for agricultural disposal systems that feed sprinklers.  In industrial applications they are used for pumping fibrous material.  Each model has a 304 stainless steel shaft with a double mechanical seal (ceramic/graphite/NBR & silicon/silicon/NBR). Single phase models are supplied with an external starter box. They are available free-standing or for guide rail mounting when supplied with the auto-coupling accessory.  Supplied with 10 metres of heavy duty rubber power cable. 

APPLICATIONS
The Cutty series comprehend electric pump with plunged impeller, this impeller is multi-pipe, open, with a cutting system in the suction. It is particularly suitable in presence of long, filamentous or fibrous fibres, of destroyable solids also of big dimensions and in biologic liquids or in civil waters.
