The transportation of large-temperature medium puts larger necessities to the framework, products and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature adjustments and the organization's applicable pump style:
1. For media 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 kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°C. It is actually value mentioning that the medium that is a snap to crystallize or includes particles should be Outfitted with a sealing floor flushing line (designed by having an axial flow pump interface).
2. For mediums previously mentioned 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), once the coolant will not be allowed to penetrate to the medium. It should be taken just after cooling its personal medium (is often realized by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element really should be cooled, but also the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is in excess of ten situations that of a normal machine seal).
