The transportation of high-temperature medium places higher specifications within the construction, components and auxiliary program from the pump. Let's talk about the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
1. For media which has a temperature decreased than one hundred twenty°C, there is normally no Unique cooling system, as well as medium by itself is used for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor ought to exceed H quality when in excess of 90°C); and DFCZ popular variety and IH chemical pump can use temperature to adopt suspension framework The upper Restrict is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump may be used approximately 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 should be Outfitted with a sealing floor flushing line (designed by having an interface).
2. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be offered click here over the pump go over. The sealing chamber shall even be linked to the coolant (with double mechanical seal), once the coolant will not be allowed to penetrate to the medium. It ought to be taken following cooling its individual medium (can be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must 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 bellows sort, but the cost is significant ( The worth is greater than 10 moments that of a standard equipment seal).
