Metallic MAG. DRIVE
Process Pumps
Product Overview

2. 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
