CVN are
vertical-shaft centrifugal pumps built from PP or PVDF thermoplastic material (parts in contact with the process liquid). They are installed on a metal baseplate with protective coating on the tank side and connected to the driving part by means of a flexible coupling. Depending on the length requested, they are fitted with between one and three shaft supports. The supports consist of extremely reliable and hard-wearing separately-flushed friction bearings. CVN pumps are available in the standard versions with lip-seal system or liquid seal to prevent the outflow of rising vapours and gases.
These pumps are typically used in all industrial sectors for the transfer of corrosive, toxic or hazardous liquids.
