The transportation of superior-temperature medium places better prerequisites over the framework, elements and auxiliary process on the pump. Let's speak about the cooling specifications of different temperature variations and the corporation's relevant pump form:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling program, and also the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around 90°C); and DFCZ typical style and IH chemical pump can use temperature to adopt suspension structure The higher limit is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately two hundred°C; only get more info 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 linked to the coolant (with double mechanical seal), once the coolant isn't permitted to penetrate into your medium. It should be taken immediately after cooling its own medium (might be understood by easy heat exchanger).
three. For top temperature medium over 300°C, not simply the pump head part has to be cooled, and also the suspension bearing chamber should be Outfitted that has a cooling system. The pump structure is usually in the form of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is significant ( The worth is more than 10 instances that of a standard device seal).
