Difference between diaphragm pumps and magnetic pumps

The difference between diaphragm pumps and magnetic pumps is reflected in various aspects, such as working principles, transport characteristics, pumping costs, structural design, performance parameters, etc. What they have in common is that they both have excellent leak-proof performance and can be used in the field of water transport with a high level of safety, without having to worry about the possibility of media leakage, see further below for details.

The unique advantages of the two types of pumps can be sorted out in order to give you a clear understanding of the difference between diaphragm pumps and magnetic pumps.

Magnetic pump: centrifugal pump body and magnetic coupling, and the transfer of motor pump movement is significantly different, is the use of magnetic force to complete the transfer of kinetic energy, does not produce mechanical friction, and therefore has a higher service life and superior safety, can effectively prevent media leakage, in the performance parameters slightly lower than the same caliber centrifugal pump, but higher than the pneumatic diaphragm pump, the medium is less adaptable, mainly transport pure water type media, including corrosive liquids, such as bleaching solution, nitric acid, ethanol, sodium hydroxide and other chemicals, while also having good tolerance to high temperatures.

Diaphragm pumps: mainly pneumatic pumps, can also be configured with motors to improve performance, compared to magnetic pumps in the internal structure design is simpler, so there is a lower failure rate, performance parameters and leak-proof grade than magnetic pumps, but both the durability of equipment or ease of use are much higher, compared to magnetic pumps require frequent attention to operating parameters, diaphragm pumps with reassuring automatic protection features, in the event of media cut-off, overload operation, clogging and other unexpected work. Compared to magnetic pumps, which require frequent attention to operating parameters, diaphragm pumps have a reassuring automatic protection function, which rarely damages the pump body in the event of media cut-off, overload operation, blockage and other unexpected conditions, and can be comparable to screw pumps to a certain extent.

Overall, the difference between diaphragm pumps and magnetic pumps is determined by the working characteristics, the user needs to select according to the actual working conditions, in general, if the transported medium is a single component of high-risk gas liquid, the choice of magnetic pumps, if the media composition is complex, or more remote environment with the pump, it is recommended to use diaphragm pumps, the relevant selection details and performance matching can be directly contacted with zhaoquan pump industry Communication, according to the actual transport needs of the batch can be customized pump type.
