The transportation of substantial-temperature medium puts bigger prerequisites to the framework, materials and auxiliary procedure on the pump. Let's speak about the cooling requirements of various temperature alterations and the corporate's applicable pump type:
one. For media by using a temperature reduced than 120°C, there is often no Specific cooling method, plus the medium itself is employed for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security degree of shielded motor really should exceed H grade when in excess of ninety°C); and DFCZ frequent style 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 utilized as many as 200°C; only CQB regular magnetic pump use temperature would not exceed 100°C. It truly is really worth mentioning which the medium that is not difficult to crystallize or incorporates particles should be Outfitted that has a sealing surface flushing line (created by having an interface).
two. For mediums over one hundred twenty°C and down below three hundred°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 get more info coolant will not be permitted to penetrate into the medium. It should be taken right after cooling its possess medium (is often understood by easy heat exchanger).
3. For prime temperature medium previously mentioned three hundred°C, not simply the pump head section needs to be cooled, but additionally the suspension bearing chamber needs to be Outfitted by using a cooling process. The pump composition is normally in the shape of the central aid. The mechanical seal is if possible a metallic bellows style, but the worth is high ( The price is more than 10 times that of a normal equipment seal).
