How to choose stainless steel magnetic pump for different media?

Release Date:2023-03-15 10:59 Views:

  Stainless steel magnetic pump corrosion resistance is mainly dependent on its use of stainless steel (304, 316, 316L) made of flow-through parts, so in the selection of stainless steel magnetic pump pumps should be based on the delivery medium to determine whether to choose which stainless steel material magnetic pumps, and should not be caught in stainless steel that is the universal corrosion-resistant pumps of the misunderstanding.

  How to choose stainless steel magnetic pump for different media

  Stainless steel magnetic pumps have the following advantages:

  1, magnetic materials and magnetic circuit design has high requirements, the rest of the technical requirements are not high.

  2, maintenance and overhaul workload is small.

  3、Transferring power with overload protection.

  4, because the drive shaft does not need to penetrate the pump casing, but the use of magnetic field through the magnetic field and isolation sleeve thin-walled transmission torque driven internal magnetic rotor, so fundamentally eliminate the leakage channel of the shaft seal, to achieve complete sealing.

  There are a variety of different specifications on the market type of stainless steel magnetic pump, how should we judge the choice?

  In addition to the operating parameters, to be transported media temperature, viscosity, whether there is a hazard, etc. should also be enough to understand, this is in order to select the corresponding production material pump type, such as the transport of acid corrosion of high pharmaceutical liquids, fluoroplastic magnetic pumps can be used to transport high temperature hot oil hot water, you can use the heat-resistant magnetic pumps for the transportation of the composition of the media attributes, to choose the specific specifications, the correct selection can effectively improve the stability and safety of the transportation process. The correct selection can effectively improve the stability and safety of the transportation process.

  Sulfuric acid is a widely used important industrial raw materials, it is in different concentrations and temperatures under different conditions on the corrosion of the material is also very different, when the concentration is greater than 80%, the temperature is less than 80 ℃, you can choose carbon steel and cast iron as a corrosion-resistant materials, but carbon steel and cast iron can not bear the high-speed flow of sulfuric acid, and therefore can not be used as a stainless steel pump pump valve material; ordinary stainless steel such as 304, 316 on sulfuric acid The corrosion resistance of ordinary stainless steel such as 304, 316 on sulfuric acid is also very limited, so the stainless steel pumps for conveying sulfuric acid are usually made of high-silicon cast iron or high-alloy stainless steel (No. 20 alloy) pumps.

  Hydrochloric acid is also very corrosive, including a variety of stainless steel materials, including most of the metal materials are not resistant to hydrochloric acid corrosion, so the transportation of hydrochloric acid can not choose stainless steel pumps.

  Many metal materials in nitric acid will be quickly corroded, stainless steel is widely used nitric acid resistant materials, all concentrations of nitric acid at room temperature have good corrosion resistance, ordinary stainless steel (such as 304, 321) in many cases on the corrosion resistance of nitric acid is even better than molybdenum-containing stainless steel (such as 316, 316L).

  Acetic acid is one of the highly corrosive organic acids, ordinary stainless steel magnetic pumps are no longer applicable, molybdenum-containing 316 stainless steel for high temperature and dilute acetic acid vapor.

  In a simple understanding of stainless steel magnetic pumps how to choose this issue, as the user does not need to worry too much about selection matters, only need to specify the necessary operating parameters in advance, you can get professional selection guidance in the Schaederbauer technicians, if there is a special demand for transportation, but also customized pumps, Schaederbauer is committed to solving the various types of transport needs of the user at the same time to provide a super cost-effective pumps, reliable! Mature pump experience and considerate and perfect after-sales technical support, can fully protect the customer's pump experience.

  Key to note: In order to avoid overloading and overloading during transportation, it is generally recommended that the actual required operating parameters based on the enlargement of 10%, reserving a certain performance space can better protect the stability of transportation. In the selection process, if the selected pump type parameters over the transportation standard, will cause unnecessary waste, but if the upper limit of performance parameters is lower than the transportation standard, it may cause overfrequency overload and other negative situations, it is recommended that in advance with the stainless steel magnetic pump manufacturer to explain the transportation needs, under the guidance of professional and technical personnel to select the type.
