The transportation of significant-temperature medium places better necessities over the composition, products and auxiliary procedure with the pump. Let us mention the cooling demands of different temperature modifications and the organization's relevant pump style:
one. For media using a temperature reduced than 120°C, there will likely be no Exclusive cooling technique, along with the medium itself is useful for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H grade when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be utilized nearly 200°C; only CQB ordinary magnetic pump use temperature would not exceed one hundred°C. It is value mentioning that the medium that is not hard to crystallize or includes particles should be equipped having a sealing floor flushing line (developed by having an interface).
2. For mediums earlier mentioned 120°C and underneath three hundred°C, a cooling chamber shall be offered over the pump go over. The sealing chamber shall even be connected to the coolant (with double mechanical read more seal), once the coolant is not really allowed to penetrate in the medium. It ought to be taken right after cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must be cooled, and also the suspension bearing chamber should be equipped by using a cooling procedure. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metal bellows kind, but the value is substantial ( The worth is more than 10 instances that of a standard device seal).
