Magnetic pump and shield pump difference：
The difference between magnetic drive pump and shield pump is not obvious from the functional use, both are specifically used to avoid medium leakage sealing pump, used to deal with some hazardous liquid, but from the structural design and working principle, is completely different, and also belongs to the sealing pump, but the seal safety level is not the same, For example, the thickness of the magnetic pump isolation sleeve is far greater than the shield pump.
About the difference between magnetic pump and shield pump, simply put, magnetic pump is a higher standard shield pump, pump cost is relatively high, because of reliable safety and is widely used to transport flammable, explosive, volatile liquid. In terms of structure, the shield pump motor is directly connected with the pump, and the rotor and stator of the motor are isolated by the shield sleeve. Cooling and lubrication are realized by the circulating cooling structure in the motor. Magnetic pump is the use of magnetic coupler to achieve no mechanical contact to transfer kinetic energy, in terms of the working principle, completely eliminate the possibility of leakage, and, between the internal and external magnetic steel sealed isolation sleeve thickness is also more than three times the general shield pump, so the safety performance is far beyond the shield pump.
Visible, compared with magnetic pump, shield pump whether the cost or maintenance costs are relatively low, belongs to the economical type of pump. And magnetic pump is suitable for higher safety level requirements of transport occasions. However, it needs to be noted that, in addition to the relatively low cost, shielding also has several other advantages, such as more compact in volume, installation more space saving, compared to the magnetic pump can deal with the medium containing some metal particles, but the same disadvantage is that the structure is too compact, so if there is a failure, the customer is difficult to repair.
As can be seen above, the difference between magnetic pump and shield pump mainly lies in the sealing performance and reliability, it is recommended to transport general liquid medicine or chemical liquid, can consider the more suitable cost-effective shield pump, and for want to suction does not contain hard particles of water, or other liquids with greater harm, the use of magnetic pump, by strictly avoiding leakage to ensure the safety of transportation conditions. In addition, if there are other special transportation needs in the selection of model specifications, you can contact saiken pump industry directly to customize the non-standard pump type.
