The transportation of high-temperature medium places bigger requirements on the structure, materials and auxiliary system of your pump. Let us mention the cooling demands of different temperature modifications and the organization's applicable pump style:
one. For media using a temperature reduced than a hundred and twenty°C, there is frequently no Specific cooling program, and also 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 undertake suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately 200°C; only CQB standard magnetic pump use temperature will not exceed a hundred°C. It truly is worth mentioning the medium that is simple to crystallize or incorporates particles must be Geared up by using a sealing surface flushing line (made with an interface).
2. For mediums higher than one hundred twenty°C and down below 300°C, a magnetic pump cooling chamber shall be presented on 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 in the medium. It should be taken soon after cooling its have medium (is often realized by uncomplicated warmth exchanger).
3. For prime temperature medium earlier mentioned three hundred°C, not just the pump head aspect needs to be cooled, but additionally the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is generally in the form of a central help. The mechanical seal is ideally a metallic bellows style, but the price is large ( The cost is in excess of ten times that of a normal machine seal).
