The transportation of substantial-temperature medium puts larger demands to the framework, resources and auxiliary technique on the pump. Let's discuss the cooling specifications of different temperature improvements and the corporation's relevant pump variety:
1. For media with a temperature lower than a hundred and twenty°C, there is often no Particular cooling method, and the medium alone is utilized for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection standard of shielded motor need to exceed H grade when about 90°C); and DFCZ widespread 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 may be used 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 click here has 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 go over. The sealing chamber shall even be connected to the coolant (with double mechanical seal), when the coolant is not really permitted to penetrate into your medium. It ought to be taken after cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head aspect must be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. The pump composition is generally in the form of a central assist. The mechanical seal is ideally a metallic bellows type, but the price is large ( The cost is in excess of ten times that of a normal machine seal).
