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.

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.
