Canned motor pumps are advanced centrifugal pumps with an electric motor hermetically-sealed and mounted on a single shaft, which in turn eliminates the requirement for mechanical seals. The entire rotating assembly of canned motor pumps is immersed in liquid, with motor stator and rotor isolated from pumped liquid by using a corrosion-resistant non-magnetic sleeve and liner. Petrol’s energy density makes it an imperative raw material in every combustible, and an irreplaceable raw material utilized in petrochemical industries for manufacturing a wide range of everyday life products. However, the environmental impact including leaks from petroleum extractions, carbon dioxide emissions and degassing effects of petrol has become a major concern among regulatory authorities. Environmental sensibilization has resulted into enforcement of standards with regard to petrochemical installations based on severe security and health protection requirements. Canned motor pumps that are leak-proof...
