Magnetic pump and peristaltic pump differences

　　Magnetic pumps and peristaltic pumps in a number of aspects there are significant differences, these differences are mainly reflected in their working principle, applicable scenes, advantages and disadvantages.

　　First, the working principle

　　Magnetic pump: magnetic pump is a kind of transmission force through the magnetic force to realize the transmission of non-leakage liquid transfer equipment. Its working principle is to use the magnetic force to make the impeller rotate, so as to transfer the liquid to the place where it is needed. Magnetic transfer medium can be gas or liquid, so it is also known as magnetic drive pump.

　　Peristaltic pump: peristaltic pump is a kind of pump through the compression and expansion of the hose in the pipeline or complex piping system to achieve fluid transfer. The working principle is to generate fluctuations through the deformation of the hose, hose compression, the negative pressure in the pipeline to suck the liquid, hose rebound when the liquid is pushed into the downstream, this working principle makes it known as peristaltic pump.

　　Second, the applicable scene

　　Magnetic pumps: Due to its leak-free characteristics, magnetic pumps are particularly suitable for conveying flammable and explosive, toxic and hazardous, high temperature and high pressure and other special occasions of the medium. These characteristics make the magnetic pump in the petroleum, chemical, metallurgy, electric power, paper, food, pharmaceutical and synthetic fiber and other sectors have a wide range of applications.

　　Peristaltic pumps: peristaltic pumps are suitable for conveying fluid flow requirements are high, the conveyor fluid churning and pressure requirements of low occasions. Because of its simple structure, easy to clean and disinfect, peristaltic pumps in the pharmaceutical, beverage, chemical, environmental protection, laboratory and other fields have a wide range of applications. Especially in the laboratory, peristaltic pumps are often used for cell tissue transport, specimen decolorization, perfusion, liquid chromatography analysis and acidic or alkaline solution transport.

　　Third, the advantages and disadvantages

　　Advantages of magnetic pumps:

　　No leakage, can well ensure the safety of the production environment.

　　Suitable for conveying flammable and explosive, toxic and harmful, high temperature and high pressure and other special occasions under the medium.

　　Simple structure, easy to maintain.

　　The life span is up to 10 years without maintenance.

　　The motor stator and circuit board part adopts epoxy resin potting and is completely isolated from the rotor, which solves the problem of water leakage caused by long-term diving of the motor-type DC water pump, and it can be installed underwater and is completely waterproof.

　　Small power consumption, high efficiency, and damping vibration damping effect.

　　Disadvantages of magnetic pump:

　　The rotational speed of the impeller is subject to the influence of the external magnetic field, and problems such as rotational speed change will occur when the magnetic field changes.

　　Higher cost, can not withstand too high a pressure.

　　Advantages of peristaltic pumps:

　　Conveying flow rate is accurate, stable, good fluid controllability.

　　Simple structure, easy maintenance.

　　Strong corrosion resistance, small shear effect.

　　Transportation of high precision, simple operation.

　　Disadvantages of peristaltic pumps:

　　Prone to wear and tear, easy pipe rupture.

　　In summary, although magnetic pumps and peristaltic pumps are used for conveying media equipment, but they have significant differences in the working principle, applicable scenarios and advantages and disadvantages. Users should be based on their own production needs and media characteristics of a reasonable choice of applicable pump type.
