CGV-S Cantilever sump pumps-Image

The CGV-S range of cantilever pumps was designed to meet a demand for vertical pumps that could operate without any risk of damage to the shaft guide bushings from abrasive solid particles contained in the fluid or from dry running, such that the design does not foresee any guide mechanisms close to the impeller.

The carbon steel 39NiCrMo3 pump shaft coated in corrosion-proof plastic, assembled in a cantilever manner and guided by strong bearings housed in the cast iron intermediate adaptor, is connected to the motor with an elastic coupling.

All parts in contact with the fluid pumped are made of thermoplastic material (PP-PVDF-PEHD-PE/UHMW); column length available ranges from 500 to 1500 mm.

ATEX 94/9/EC certificates are available for the CGV-S range.
