The transportation of substantial-temperature medium puts increased prerequisites over the composition, products and auxiliary procedure of your 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 should really exceed H grade when over ninety°C); and DFCZ frequent 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 used nearly 200°C; only CQB ordinary magnetic pump use temperature would not exceed one hundred°C. It's worthy of mentioning that the medium that is easy to crystallize or click here is made up of particles ought to be Geared up having a sealing area flushing line (created having an interface).
2. For mediums higher than 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 allowed to penetrate in the medium. It should be taken soon after cooling its have medium (could be recognized by simple heat exchanger).
three. For top temperature medium above 300°C, not simply the pump head part has to be cooled, and also the suspension bearing chamber should be equipped by using a cooling procedure. The pump structure is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The price is greater than 10 moments that of a traditional equipment seal).
