DESIGNING INDUSTRIAL PUMPS
ATEX CERTIFIED CHEMICAL PUMPS
Savino Barbera pumps can also be provided with ATEX Certification to enable them to work safely with flammable liquids and in the presence of potentially explosive atmospheres (Zone 1 and Zone 2). Pumps with these explosion-proof properties are: magnetic drive pumps (electric centrifugal pumps), double diaphragm pumps (air driven pumps) and drum transfer pumps (electric centrifugal pumps). Outside of these types, all other Savino Barbera chemical pumps can be equipped with ATEX explosion-proof motors (where only the motor has ATEX approval).
ATEX magnetic pumps
Magnetic drive pumps with ATEX certification. BM magnetic pumps are certified for use in ATEX Zone 2 environments (both plastic and metal versions) and ATEX Zone 1 (metal version). The construction materials in contact with liquids are: acid-proof plastic (PP, PVDF) and stainless steel (AISI 316).
ATEX DIAPHRAGM PUMPS
Air-operated double diaphragm pumps, Atex compliant. Standard materials used for all models of pneumatic pumps: non-conductive plastic and metal (for use in Zone 2). Conduct" series on request: pumps made of metal or conductive plastic loaded with carbon fibre (for use in Zone 1).
ATEX drum transfer pumps
The only drum pump for ATEX classified areas is the TR JP in metal (AISI 316), in both electric and pneumatic versions. For pneumatic drum pumps operated in potentially explosive environments, the supply air must have a temperature not exceeding the limits of the ATEX environment (-20°C to +40°C max).
