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 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 quality 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 consists of particles need to be Outfitted which has a sealing surface area flushing line (built using an interface).
two. For mediums over 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), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its possess medium (is usually realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion needs to be cooled, but in addition the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a steel bellows form, but the worth is higher ( The worth is click here greater than 10 instances that of a standard device seal).
