The transportation of superior-temperature medium places higher specifications within the construction, components and auxiliary program in the pump. Let's discuss the cooling specifications of different temperature changes and the corporation's relevant pump form:
1. For media using a temperature reduce than a hundred and twenty°C, there will likely be no Exclusive 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 (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 construction The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed one hundred°C. It is website actually value mentioning that the medium that is not hard to crystallize or includes particles should be Outfitted having a sealing floor flushing line (developed by having an interface).
2. For mediums earlier mentioned 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 allowed to penetrate in the medium. It should be taken soon after cooling its have medium (could be understood by simple heat exchanger).
three. For top temperature medium above 300°C, not simply the pump head part should be cooled, but will also the suspension bearing chamber ought to be Outfitted that has a cooling system. The pump construction is mostly in the shape of the central support. The mechanical seal is preferably a metallic bellows kind, but the value is substantial ( The worth is more than 10 instances that of a standard device seal).
