The transportation of significant-temperature medium puts better prerequisites over the composition, elements and auxiliary process with the pump. Let's speak about the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature lower than 120°C, there is usually no Unique cooling system, as well as medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor ought to exceed H quality when above 90°C); and DFCZ prevalent variety and IH chemical pump can use temperature to adopt suspension framework The upper Restrict is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°C. It is actually well worth mentioning which the medium that is a snap to crystallize or consists of particles need to get more info be Outfitted which has a sealing surface area flushing line (designed using an interface).
two. For mediums previously mentioned a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), once the coolant will not be allowed to penetrate to the medium. It ought to be taken following cooling its possess medium (can be recognized by uncomplicated 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 structure is generally in the form of a central guidance. The mechanical seal is if possible a metal bellows kind, but the value is significant ( The worth is over ten times that of a normal machine seal).
