The transportation of significant-temperature medium puts better prerequisites over the composition, elements and auxiliary process with the pump. Let us mention the cooling needs of various temperature alterations and the business's applicable pump type:
one. For media that has a temperature decrease than 120°C, there is generally no Distinctive cooling process, 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 frequent kind 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 well worth mentioning which the medium that is not difficult to crystallize or consists of particles really should be equipped which has a sealing surface area flushing line (built with the interface).
two. For mediums over one hundred twenty°C and below three hundred°C, a cooling chamber shall be provided about the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), when the coolant will not be permitted to penetrate in to the medium. It ought to be taken after cooling its possess medium (could be understood by easy heat exchanger).
three. For top temperature medium over three hundred°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 check here cooling system. The pump construction is mostly in the shape of the central support. 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).
