The transportation of high-temperature medium places higher specifications around the structure, supplies and auxiliary program from the pump. Let's take a look at the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
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 standard of shielded motor need to exceed H grade when around 90°C); and DFCZ common style 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 truly worth mentioning the medium that is simple to crystallize or has particles needs to be Geared up using a sealing area flushing line (created having an get more info 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 isn't allowed to penetrate into your medium. It ought to be taken soon after cooling its own medium (could be understood by simple heat exchanger).
three. For top temperature medium over 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 procedure. The pump structure is usually in the shape of the central guidance. The mechanical seal is if possible a metal bellows kind, but the value is significant ( The worth is more than 10 occasions that of a standard device seal).
