The transportation of significant-temperature medium places increased necessities over the composition, elements 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 reduce than 120°C, there will likely be no Exclusive cooling technique, as well as the medium itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor really should exceed H grade when over ninety°C); and DFCZ frequent type and IH chemical pump can use temperature to undertake suspension construction The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used as many as 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be really worth mentioning which the medium that is straightforward to crystallize or consists of particles need to be Outfitted which has a sealing surface area flushing check here line (designed using an interface).
two. For mediums earlier mentioned 120°C and underneath 300°C, a cooling chamber shall be presented on the pump protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant is not really allowed to penetrate in the medium. It should be taken right after cooling its have medium (could be recognized by simple heat exchanger).
3. For top temperature medium above 300°C, not simply 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 the central guidance. The mechanical seal is if possible a metal bellows kind, but the value is significant ( The worth is more than 10 instances that of a standard device seal).
