YPPC MAG. DRIVE PUMP
IntroductionIntroduction
• Definition of Magnetic drive pump
-. A type of Sealless Pump -. Utilizes an outer ring of permanent
magnets to drive an internal rotating assembly consisting
of an impeller, shaft, and inner drive member through
a corrosion resistant containment shell
• Application
-. Hazardous and toxic fluids -. Heat transfer fluids -. Where high seal maintenance costs
are considerations • Requirement for sealless pumps
-. Based on the need for a clean and safe environment
