Features

Magnetic power transmission

No leakage

Seal-less pump

Hermetic system
Magnetic drive series

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.

Benefits:

No mechanical seal problems

Safe working environment and environmental friendly

Safe handling of hazardous fluids

No poisonous or dangerous vapors

How it Works:

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.

Working Principle:
  1. Drive magnet, connected to the motor
  2. Isolation shell (rear housing) separating the liquid side from the atmosphere
  3. Impeller magnet assembly, driven by the drive magnet
