BBC Semisom 300 GR 230v Auto

They are supplied with a grinder whose blades in forged and tempered stainless steel allow to chop the solids and filaments
in the waste or sewage water and thus to expel them even through relatively small pipeworks or when high head is required.
They are recommended to pump waste water coming from domestic, civil and industrial installations as well as the drainage of
septic tanks.
