Magnet Driven Chemical Pumps safely handle hazardous, highly corrosive, explosive and toxic chemicals. They provide safe, leak-proof service because the magnetic coupling eliminates the need for traditional sealing methods, such as mechanical seals or gland packing, which is the main source of leakage problems on pumps. As a result, down time and maintenance cost is greatly reduced and there are no warn seals to replace. These chemical pumps minimizes exposure of humans to hazardous chemicals, eliminates contacting seal faces, which are prone to wear and leakage, provides superior corrosion resistance, reduces downtime and maintenance costs and also eliminates alignment problems inherent in direct-coupled units. These chemical pumps are ideal for vacuum service and transfer of expensive, toxic, radio active, hazardous and corrosive chemicals.
