The transportation of higher-temperature medium places higher specifications around the structure, supplies and auxiliary method of your pump. Let us look at the cooling necessities of different temperature adjustments and the organization's applicable pump style:
one. For media by using a temperature reduced than 120°C, there is usually no Distinctive 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 really should exceed H grade when over ninety°C); and DFCZ frequent type 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 really worth mentioning which the medium that is not difficult to crystallize or contains particles really should be equipped that has a sealing surface area flushing line (intended with the interface).
two. For mediums over 120°C and underneath 300°C, a cooling chamber shall be presented on the pump deal with. 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 own medium (could be understood 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 form of the central guidance. The mechanical seal is if possible a metal here bellows kind, but the value is significant ( The worth is more than 10 instances that of a standard device seal).
