There are many liquids that require tight containment and not allow any leakage. Liquids can be environmentally sensitive such as amines, volatile like LPG or dangerous to human health such as chlorine. When leakage to atmosphere cannot be tolerated pumps can utilise dual seals with complex seal systems or sealless pumps can be installed.
AFH are experts in the supply of sealless pumps both in canned motor and magnetic drive technology. This paper briefly discusses both technologies and their benefits.
