Tapflo magnetic drive pumps
CTM pumps are used in most industries where liquids are pumped. The pumps handle many types of low and normal viscous clean liquids such as chemical aggressive and toxic.
How they work
The power from the motor is transmitted to the centrifugal impeller by means of a magnetic coupling. A so called isolation shell between the drive magnet and the impeller magnet separate the liquid side from the drive.
Typical applications
| Industry | Example of application |
| Chemical stockists |
Transfer of various chemicals from storage tanks to smaller containers |
| Surface treatment | Transfer, filtering and circulation of surface treatment baths |
| Food and beverage | Pumping of CIP detergent used for cleaning of pipes and other food process equipment |
| Water treatment | Dosing of acids and alkalis used as cleaning chemicals in nanofiltration |
| Chemical manufacture | Pumping of chemicals in industrial detergent equipment |
| Demineralizing | Demi-water circulation and transfer in many industrial applications |
| Photo processing | Transfer of photo develop chemicals and inclusion in processing machines |
| Liquid crystal manufacture | Pumping of concentrated acids and alkalis |
