The transportation of significant-temperature medium places better prerequisites on the composition, products and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature modifications and the organization's applicable 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 employed for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor should exceed H quality when more than ninety°C); and DFCZ widespread sort and IH chemical pump can use temperature to undertake suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized nearly two hundred°C; only CQB ordinary get more info magnetic pump use temperature won't exceed one hundred°C. It is actually value mentioning that the medium that is a snap to crystallize or includes particles should be Outfitted with a sealing surface area flushing line (designed using an interface).
two. For mediums over a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be provided 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 previously mentioned three hundred°C, not only the pump head element really should be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling technique. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the value is substantial ( The cost is much more than ten times that of a normal machine seal).
