The transportation of substantial-temperature medium puts increased necessities over the composition, products and auxiliary procedure of your pump. Let us look at the cooling necessities of different temperature adjustments and the organization's applicable pump type:
one. For media with a temperature lessen than one hundred twenty°C, there is often no Particular cooling method, and the medium alone is utilized for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security standard of shielded motor must exceed H grade when about 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 around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It really is worth mentioning the medium that is simple to crystallize or incorporates particles needs to be Geared up by using a sealing area flushing line (made with an interface).
2. For mediums higher than 120°C and underneath 300°C, a cooling chamber shall be presented on the pump protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant is not really allowed to penetrate in the medium. It ought to be taken soon after cooling its own medium (could be understood by simple heat exchanger).
three. For check here 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 a central guidance. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The cost is much more than 10 occasions that of a standard device seal).
