The transportation of large-temperature medium puts larger demands to the framework, resources and auxiliary technique on the pump. Let's speak about the cooling needs of different temperature changes and the company's relevant pump variety:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling program, and 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 typical style and IH chemical pump can use temperature to adopt suspension structure 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 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 around 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 into your 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 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 cost is higher ( The value is in excess of ten times that of a normal website machine seal).
