The transportation of superior-temperature medium places bigger prerequisites on the composition, materials and auxiliary system of your pump. Let us look at the cooling necessities of different temperature adjustments and the organization's applicable pump type:
one. For media by using a temperature reduced than 120°C, there is usually no Distinctive cooling process, along with the medium alone 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 quality 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 used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°C. It is actually value mentioning click here that the medium that is a snap to crystallize or includes particles should be Outfitted with a sealing floor flushing line (designed using an interface).
two. For mediums previously mentioned a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall also be linked to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its very own medium (is usually realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned 300°C, don't just the pump head component should be cooled, but will also the suspension bearing chamber ought to be Outfitted that has a cooling system. The pump construction is mostly in the shape of the central aid. The mechanical seal is preferably a metal bellows variety, but the cost is superior ( The price is over 10 moments that of a traditional equipment seal).
