The transportation of higher-temperature medium places higher needs to the composition, materials and auxiliary technique on the pump. Let us take a look at the cooling needs of different temperature changes and the company's relevant pump variety:
1. For media having a temperature lower than 120°C, there is usually no Particular cooling method, as well as the medium by itself is utilized for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical style and IH chemical pump can use temperature to undertake suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be used approximately 200°C; only CQB normal magnetic pump use temperature would not exceed a hundred°C. It truly is value mentioning that the medium that is straightforward to crystallize or consists of particles ought to be equipped that has a sealing surface flushing line (intended with the interface).
two. For mediums above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), when the coolant will not be allowed to penetrate into your medium. It ought to be taken after cooling its have medium (could be realized by basic heat exchanger).
3. For top temperature medium previously mentioned three hundred°C, not only the pump head element ought to be cooled, but also the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is if possible a metal bellows kind, but the price is substantial ( The value is a lot more more info than 10 occasions that of a standard machine seal).
