What are the advantages and disadvantages of electromagnetic pump

The advantages and disadvantages of electromagnetic pumps can be summarized as follows:Advantages:
High accuracy: the electromagnetic pump can precisely adjust the flow rate to meet the high precision flow requirements.
Good safety: The electromagnetic pump does not use flammable and explosive liquids, avoiding the risk of fire and explosion.
Long service life: The electromagnetic pump works in a unique way, without mechanical contact, so the service life is relatively long.
Non-contact transport: The electromagnetic pump can transport the liquid without contact, avoiding the possibility of contamination of the liquid.
Strong adjustability: the electromagnetic pump can adjust the flow and pressure according to the need, with high flexibility.
Energy saving: The electromagnetic pump can effectively save energy during the working process.
Simple operation: The use and operation of the electromagnetic pump is relatively simple, reducing the operating cost.
Widely used: electromagnetic pumps have been widely used in chemical drug transportation, food and beverage processing, petrochemical transportation and medical equipment and other fields.
Cons:
Low efficiency: Although the efficiency of the electromagnetic pump can reach more than 70%, its efficiency is still low compared to other types of pumps.
Limited transmission capacity: the electromagnetic pump can only transport clean liquid, and the transmission capacity is limited, can not transport a large amount of liquid or liquid containing impurities.
High cost: The cost of electromagnetic pumps is high and may not meet the needs of most users.
High requirements for manufacturing materials: The structure of some electromagnetic pumps (such as DC flat electromagnetic pumps for casting) has very high requirements for manufacturing materials, which is difficult to manufacture and high cost.
Need preheating: Some electromagnetic pumps (such as DC flat electromagnetic pumps for casting) require preheating and inversion in air at high temperatures, which increases the complexity and cost of use.
Low utilization rate of liquid metal: For some electromagnetic pumps (such as DC flat electromagnetic pumps for casting), the required crucible size is large, which may lead to low utilization rate of liquid metal.
In summary, the electromagnetic pump has significant advantages in precision, safety, service life, non-contact transportation, adjustable, energy saving and simple operation, but there are obvious shortcomings in efficiency, transportation capacity, cost, manufacturing material requirements, preheating requirements and liquid metal utilization. Therefore, when choosing whether to use electromagnetic pumps, it is necessary to weigh them according to specific application scenarios and needs.
