The transportation of higher-temperature medium places higher requirements around the structure, materials and auxiliary system on the pump. Let us take a look at the cooling prerequisites of various temperature adjustments and the business's applicable pump type:
one. For media by using a temperature reduced than 120°C, there is usually no Distinctive cooling process, along with the medium itself is useful for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H grade when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning which the medium that is not difficult to crystallize or contains particles really should be equipped that has a sealing surface flushing line (intended with the interface).
two. For mediums above 120°C and underneath 300°C, a cooling chamber shall be furnished around 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 (could be understood by simple heat exchanger).
three. For high temperature medium previously mentioned three hundred°C, not just the pump head portion really should be cooled, but additionally the suspension bearing chamber really should be Geared up having chemical pump a cooling technique. The pump framework is normally in the shape of a central help. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is a lot more than ten situations that of a normal machine seal).
