Why is a coupling needed for magnetic pump?
Thread Content
Why is a coupling needed for the IMC type magnetic pump in Taicang? Why isn’t the motor shaft connected directly to the outer magnet? . . The two images show magnetic pump couplings with and without couplings respectively; could someone expertly analyze the advantages and disadvantages of each?
The advantage of a direct connection is that it requires less space, is easy to install, and does not require the removal of pipes during maintenance, making it convenient for repairs.
What are the advantages of adding a coupling?
Those with couplings provide cushioning during startup, offering better stability. There are advantages and disadvantages to each approach compared to direct connection, but for larger models, it is generally recommended to use those with couplings.
There are also those with a direct connection base
The magnetic coupling of a magnetic pump is cooled by the medium that the pump transports. If there are hard particles in this medium, it can easily cause scratches or punctures in the isolation sleeve; sometimes, improper maintenance methods can also lead to damage to the isolation sleeve
1. Save magnets 2. Reduce eddy current losses in the isolation sleeve
One is a horizontal motor, and the other is a vertical motor
Direct connection has its advantages, such as smaller floor space and no need to adjust concentricity; whereas connections using couplings result in lower maintenance costs~~
The manufacturer states that the version with a coupling provides cushioning during startup, resulting in better stability. There are advantages and disadvantages to each option compared to a direct connection, but for larger models, it is generally recommended to use the version with a coupling. 】
