The transportation of superior-temperature medium places better prerequisites over the composition, products and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature modifications and the organization's relevant pump style:
one. For media using a temperature reduced than 120°C, there is usually no Exclusive cooling process, as well as the medium itself is useful for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H quality when more than ninety°C); and DFCZ widespread kind 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 may be used 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 using a sealing area flushing line (created having 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 check here is not allowed to penetrate in the medium. It ought to be taken right after cooling its have medium (may be recognized by very simple heat exchanger).
3. For top temperature medium above 300°C, not merely the pump head section must be cooled, and also the suspension bearing chamber need to be equipped by using a cooling process. The pump structure is generally in the form of a central assist. The mechanical seal is if possible a metal bellows kind, but the value is significant ( The worth is more than 10 instances that of a standard device seal).
