YPPC’s Metallic MAG. DRIVE Process Pumps Product Overview

Introduction 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
