The transportation of substantial-temperature medium puts larger necessities to the framework, elements and auxiliary process with the pump. Let us mention the cooling demands of different temperature modifications and the organization's applicable pump style:
one. For media by using a temperature decrease than 120°C, there is usually no Distinctive cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor should exceed H quality when above 90°C); and DFCZ common form and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It truly is worth mentioning the medium that is straightforward to crystallize or incorporates particles must be equipped by using a sealing surface flushing line (made with an interface).
two. For mediums above one hundred twenty°C and down below 300°C, a cooling chamber shall be furnished around the pump deal with. The sealing chamber shall also be connected to the coolant (with double mechanical seal), if the coolant isn't allowed to penetrate into your medium. It should be taken soon after cooling its own medium (could be understood by easy heat exchanger).
three. For top temperature medium over 300°C, not simply the pump head part should be cooled, but will also the suspension bearing chamber ought to be Outfitted that has a cooling system. The pump construction is usually in the shape of the central support. The mechanical seal is preferably a steel bellows variety, but the worth is high ( The price is over read more ten periods that of a traditional equipment seal).
