The transportation of significant-temperature medium puts better demands to the composition, products and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature adjustments and the business's applicable pump type:
one. For media by using a temperature decrease than 120°C, there is usually 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 (defense degree of shielded motor should exceed H quality when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The upper Restrict is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be utilized nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed one hundred°C. It is actually value mentioning that the medium that is not hard to crystallize or includes particles really should be equipped that has a sealing surface area flushing line (built with the interface).
two. For mediums over a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be provided about the pump cover. 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 possess medium (is usually realized by uncomplicated warmth exchanger).
3. For prime temperature medium earlier mentioned 300°C, not just the pump check here head aspect needs to be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. 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 occasions that of a normal device seal).
