How to Use a Magnetic Drive Pump Correctly
2024-10-16
What should you pay attention to when using a self-priming magnetic drive pump so that it works at its best? Many people want to know the answer, so today, as a pump manufacturer, we have put together some precautions for using magnetic drive pumps correctly. If you are not familiar with them, take a look.
1. During use, be sure to note that no check valve should be fitted on the pump's discharge line. If a check valve must be used, a vent hole should be provided below the valve.
2. When the self-priming magnetic drive pump is in operation, the flow rate, head, and suction lift must be kept within the rated ranges. If they deviate greatly from the specified values, the pump may run dry and fail to operate normally.
3. It is strictly forbidden to convey fluids containing solid particles or crystallizing media.
4. When restarting the pump after a long period out of service, first check whether there is enough liquid inside the pump body, and only allow it to self-prime once the liquid has been topped up.
5. After the self-priming magnetic drive pump has been installed as required, you can connect the power supply and use the jog (inching) method to check whether the pump rotates normally and freely.
6. The self-priming magnetic drive pump must never be allowed to run dry, so when the liquid is nearly pumped out, someone should be specifically assigned to watch it to prevent the liquid from being completely drained.
In addition, the self-priming magnetic drive pump must never be run dry or run unloaded, because for this type of pump it is the conveyed medium itself that provides cooling and lubrication. Running it unloaded can easily burn out the motor of the self-priming magnetic drive pump. When using the pump, a strainer should be installed at its suction inlet; in particular, because the self-priming magnetic drive pump relies on magnetic force to operate, you must guard against the ingress of ferrous material, so a magnetic filter should be added to the strainer.
The motor of the self-priming magnetic drive pump operates best at a working temperature below 40 °C, and care should be taken that it does not exceed 75 °C. We recommend that the self-priming magnetic drive pump not be used to convey liquids containing particles or fibrous material; after conveying media that crystallize easily, the pump should be cleaned promptly, otherwise its maintenance will suffer. If the pump runs for more than one thousand hours, routine servicing and potential fault clearing should be carried out by qualified personnel. During operation, cavitation is a common hazard for self-priming magnetic drive pumps, so it deserves particular attention.
