The transportation of substantial-temperature medium places better demands within the structure, elements and auxiliary technique from the pump. Let us speak about the cooling requirements of various temperature modifications and the company's applicable pump type:
one. For media with a temperature decreased than 120°C, there will likely be no Specific cooling system, along with the medium itself is utilized for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection level of shielded motor need to exceed H quality when above ninety°C); and DFCZ typical form and IH chemical pump can use temperature to adopt suspension construction The higher limit is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump can be used approximately click here two hundred°C; only CQB normal magnetic pump use temperature won't exceed a hundred°C. It really is worthy of mentioning that the medium that is not difficult to crystallize or incorporates particles needs to be Outfitted which has a sealing surface flushing line (made having an interface).
2. For mediums over one hundred twenty°C and down below 300°C, a cooling chamber shall be supplied about the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), once the coolant is just not permitted to penetrate into your medium. It ought to be taken following cooling its very own medium (is often understood by very simple heat exchanger).
3. For high temperature medium over 300°C, not merely the pump head portion really should be cooled, but also the suspension bearing chamber ought to be equipped using a cooling program. The pump framework is mostly in the shape of a central assist. The mechanical seal is ideally a steel bellows type, but the value is large ( The value is a lot more than 10 moments that of a standard device seal).
