The transportation of higher-temperature medium places greater needs within the framework, materials and auxiliary program on the pump. Let's discuss the cooling specifications of different temperature variations and the corporation's relevant pump variety:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling method, and the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume 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 higher limit is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately 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 must be equipped by using a sealing surface flushing line (made by having an interface).
2. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be supplied over check here 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 warmth exchanger).
3. For prime temperature medium higher than 300°C, not just the pump head aspect needs to be cooled, but in addition the suspension bearing chamber really should be equipped using a cooling technique. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the price is large ( The cost is much more than ten times that of a normal machine seal).
