Magnetic Drive Centrifugal Pumps are a type of pump used to prevent liquid leakage under specific conditions or when there is a need to transfer hazardous or toxic chemicals. These pumps utilize a magnetic system to transfer power to the pump shaft without requiring a direct mechanical connection between the motor and the pump.

Main Components of Magnetic Drive Centrifugal Pumps:

1. Electric Motor:

- This part provides mechanical energy to set the pump in motion.

2. Magnetic Drive:

- One of the key features of these pumps is the use of a magnetic system that transfers power from the motor to the pump shaft. This system consists of two magnetic assemblies, one located in the motor section and the other in the pump section.

3. Internal Shaft:

- The internal shaft, which moves inside the pump, is rotated by magnetic forces generated from the external shaft (which is connected to the motor).

4. External Magnet:

- This magnet is located outside the pump and is connected to the motor. Its function is to transfer rotational force to the internal shaft.

5. Internal Magnet:

- This magnet is located inside the pump chamber and causes the internal shaft to rotate.

6. Pump Casing:

- The pump casing is responsible for holding and protecting the internal components of the pump. This casing is usually made from corrosion-resistant and pressure-resistant materials.

7. Pump Cover:

- This part covers the pump casing and prevents liquid leakage.

8. Seals:

- Magnetic pumps require seals that prevent liquid leakage at the shaft contact areas. These seals are usually available in two types: mechanical seals and magnetic seals.

9. Impeller:

- The impeller is a rotating component that generates the necessary force to transfer the liquid. This part is located inside the pump casing and transfers kinetic energy to the liquid.

Advantages of Magnetic Drive Centrifugal Pumps:

- No liquid leakage: Due to the use of a magnetic system, there is no need for sealing shafts or sealing strips, and liquid cannot leak from the pump.

- Environmental protection: Due to the non-leakage feature, these pumps are very suitable for transferring hazardous or toxic chemicals that may be harmful to the environment.

- Energy savings: These pumps typically have high efficiency and operate with minimal energy consumption.

- Low maintenance requirements: Due to the design without a mechanical shaft that directly contacts the liquid, they require less maintenance and fewer part replacements.
