The transportation of large-temperature medium puts increased necessities over the composition, elements and auxiliary procedure with the pump. Let us mention the cooling needs of different temperature changes and the company's relevant pump variety:
1. 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 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 double suction pump the medium that is not difficult to crystallize or consists of particles really should be equipped that has a sealing surface flushing line (intended with the interface).
two. For mediums above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered around the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), in the event the coolant isn't permitted to penetrate into your medium. It should be taken soon after cooling its personal medium (might be understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element ought to be cooled, but also the suspension bearing chamber needs to be Geared up which has a cooling method. The pump framework is mostly in the shape of the central assistance. The mechanical seal is ideally a steel bellows form, but the worth is higher ( The value is a lot more than ten situations that of a traditional machine seal).
