Why do magnetic gear pumps not leak?

One of the main advantages of a magnetic gear pump is its fully sealed design without a mechanical seal. This completely eliminates fluid leaks even when working with aggressive and hazardous media.

1. What does "leak-free" mean?

Conventional pumps use mechanical seals that wear out over time and can leak fluid.

In magnetic gear pumps, the design completely isolates the working fluid from the external environment.

2. How does magnetic drive work?

The main principle lies in the magnetic coupling:

• The outer magnet is connected to the motor
• The inner magnet is connected to the pump rotor
• Rotation is transmitted through a magnetic field
• There is no physical contact between the shafts

 This completely eliminates the possibility of leakage through the shaft.

3. Sealed pump design

The internal pump chamber is completely isolated.

This means:

• no shaft seals
• no mechanical seals
• no direct shaft output to the outside
