The transportation of higher-temperature medium places higher specifications within the construction, components and auxiliary program in the pump. Let's discuss the cooling requirements of different temperature modifications and the organization's relevant pump style:
one. 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 degree of shielded motor should exceed H quality when above ninety°C); and DFCZ widespread sort and IH chemical pump can use temperature to undertake suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized up to two hundred°C; only CQB normal magnetic pump use temperature would not exceed one hundred°C. It is worthy of mentioning that the medium that is not hard to crystallize or is made up of particles ought to be Geared up having a sealing floor flushing line (developed having an interface).
2. For mediums earlier mentioned 120°C and underneath 300°C, a cooling chamber shall be presented on the pump deal with. 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 immediately magnetic pump 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 must be Geared up with a cooling program. The pump framework is normally in the shape of a central help. The mechanical seal is ideally a metallic bellows style, but the price is large ( The cost is in excess of ten times that of a normal machine seal).
