How to Choose a Right Magnetic Drive Pump

Magnetic drive pump is a new type of seal-less pump which applies the principle of permanent magnetic drive technology to realize contactless transmission of torque. As a non-leakage, non-polluting fluid transfer equipment, the type of pump without sealing, can achieve zero leakage, especially suitable for transporting flammable, explosive, volatile, toxic, corrosive and precious liquids, magnetic drive pumps are mostly used for the requirements of the pump can only be slightly leaky or even non-leakage occasions, as well as mechanical seals are more difficult to cope with the occasion of a high vacuum, is now widely used in many industrial fields.

However, due to the existence of a variety ofmodels and specifications of magnetic drive pumps on the market, in order to ensure the selection of suitable magnetic drive pumps, need to consider some key points. In this article, we will analyze how to choose the right magnetic drive pump to help readers make an informed decision during the purchasing process.

Consider the Process Requirements

• Flow requirements: Determine the required flow range to ensure that the magnetic drive pump can meet the expected fluid transfer requirements.
• Head requirements: According to the height difference of the conveyed fluid and friction resistance, to determine the required head range.
• Temperature requirements: To understand the temperature range of the conveyed fluid, to select the appropriate magnetic drive pump materials and sealing systems. 

Material Selection

Magnetic drive pumps are usually made of stainless steel, plastic and other materials. According to the nature of the conveyed liquid, it is very important to choose the material that is compatible with it in order to avoid the problem of material corrosion or leakage. For corrosive or high hygiene requirements of the occasion can choose stainless steel pump. For corrosive liquids, choose materials with good corrosion resistance, such as 316 stainless steel. For chemical transportation, you can choose chemical-resistant plastic materials.

Sealing Systems

The sealing system of a magnetic drive pump is a critical component in preventing leakage. Common sealing systems include static and dynamic seals. Static seals use static seals or isolation housings to prevent leakage and are suitable for conveying low-viscosity liquids.

Dynamic seals use mechanical seals and are suitable for conveying high-viscosity or corrosive liquids. Select the appropriate sealing system according to the specific requirements and ensure its reliability and ease of maintenance.

Functionality and Safety

Adjustable Flow and Head:

For example, the selection of magnetic water pumps should be based on the design flow, the required head selection of pumps, and consider the magnetic water pump due to wear and tear and other reasons caused by the magnetic water pump force decline, according to the calculation of head H multiplied by a factor of 1.05~1.10 to select the pump.

Should be selected due to the flow characteristic curve resulting in a gradual decline in the head of the magnetic water pump, so that the pumps are stable and reliable parallel operation. The operating point of the magnetic water pump should be kept in the high efficiency area of the magnetic water pump operation, which is not only energy-saving and not easy to damage the machine parts.

Some applications may require adjustable flow and head depending on the situation, so choosing a magnetic drive pump with adjustable flow and head features is a wise choice.

Overload Protection and Troubleshooting:

Magnetic eddy current loss is expressed in the form of heat, which will reduce the efficiency of the whole machine by 1%~7%. At the same time, it will make the temperature of the isolation sleeve rise, once the temperature at the isolation sleeve rises above the maximum use temperature of the permanent magnet, it will have an impact on the use of the permanent magnet. Therefore, in the design of the magnetic pump, the temperature of the isolation sleeve must be controlled to ensure the safe and reliable operation of the permanent magnet.

Compared with ordinary pumps, magnetic pumps have the advantages of being fully enclosed and leak-free, so that they can achieve the purpose of anti-virus, explosion-proof, and ensure safe production. At the same time, it also shortens the contact time between the operator and toxic, harmful, flammable, and explosive media. The operator's safety and health play a role in safeguarding. Some advanced magnetic drive pumps have overload protection and troubleshooting features that can detect andprevent equipment overloads or malfunctions promptly, improving operational safety.

Silence and Vibration Control:

Choosing a magnetic drive pump with noise reduction and vibration control features can reduce operating noise and vibration, providing a better working environment.

Brand Reputation and After-sales Service:

Choosing magnetic drive pumps from well-known brands can provide better quality assurance and reliable after-sales service. The brand's reputation and long-term market performance are important indicators for assessing the quality and performance of its products. In addition, understanding the after-sales service policy, feasibility of repairs, and replacement parts are also considerations in decision-making.

Cost and Value for Money

Considering the cost and value for money of magnetic drive pumps should focus not only on the purchase cost but also on the life of the equipment, energy consumption, and maintenance costs.

Choosing a magnetic drive pump with low operating costs and long service life can help reduce the total cost of ownership.
Selecting the right magnetic drive pump is a comprehensive process based on key points such as process requirements, material selection, sealing systems, functionality and safety, brand reputation and after-sales service, as well as cost and value for money.
