How to Repair a Magnetic Pump?

Magnetic Pump Repair

Magnetic pump is a common chemical pump in industrial applications, mainly used in chemical processing, pharmaceuticals and wastewater treatment. Compared with traditional centrifugal pumps, they are more suitable for handling corrosive or hazardous fluids, while maintaining low maintenance costs. However, magnetic drive pumps, like other mechanical equipment, sometimes need maintenance. The next chapter will introduce how to maintain magnetic drives.

Step 1: Identify the problem

To repair a magnetic pump, you must first find out the problem. Common problems with magnetic pumps include leakage, low flow rate, and vibration. When you find a problem, you should inspect the pump to determine the cause of the problem.

If you notice any of these problems, you should check the pump to determine the cause of the problem.

Step 2: Check the pump

When you have located the problem, you should inspect the pump to determine the cause of the problem.

This may require disassembling the pump and inspecting magnetic pump components such as impellers, magnetic couplings, housings, etc.

Step 3: Replace damaged components

If damaged or worn parts are found during the inspection, they should be replaced promptly. If the damage is serious, you can also replace the damaged one with a new one.

QEEHUA PUMP is a manufacturer of magnetic pumps. Its products are corrosion-resistant and durable, and have been recognized by many customers.

Step 4: Reassemble the pump

After replacing damaged parts, the magnetic pump should be reassembled, making sure that all parts are installed correctly and within specifications. After replacing the new magnetic pump, you should check whether the pump is operating normally.

Step 5, Test the Pump

After the pump has been reassembled, it should be tested to ensure it is functioning properly.

This may involve running the pump at various flows and pressures to ensure it performs within the manufacturer’s specifications. You should also check for leaks and vibrations during the test.

Step 6: Maintain the Pump

In order to prevent possible problems with the magnetic pump in the future, a regular maintenance plan should be established, including regular inspections of the pump for wear or damage, leakage, corrosion, etc.


Through the above steps, you can quickly identify problems and formulate corresponding solutions. With a regular maintenance plan, you will no longer worry about the damage to the magnetic pump affecting production
