The transportation of significant-temperature medium puts better prerequisites over the construction, elements and auxiliary process with the pump. Let us speak about the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature lower than a hundred and twenty°C, there will likely be no Exclusive cooling technique, as well as the medium itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor really should exceed H grade when over ninety°C); and DFCZ frequent type 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 as many as 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 consists of particles need to be equipped which has a sealing floor get more info flushing line (made with an interface).
two. For mediums above one hundred twenty°C and down below 300°C, a cooling chamber shall be furnished around the pump cover. The sealing chamber shall also 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 individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is more than 10 instances that of a standard device seal).
