The transportation of higher-temperature medium puts greater needs about the construction, resources and auxiliary technique in the pump. Let's discuss the cooling specifications of various temperature variations and the corporation's applicable pump type:
one. For media that has a temperature decrease than 120°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor need to exceed H quality when more than 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 nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed one hundred°C. It is actually value mentioning that the medium that is not hard to crystallize or includes particles needs to be Geared up by using a sealing surface flushing line (made with an interface).
2. For mediums higher than one hundred twenty°C and down below 300°C, a cooling chamber shall be furnished around 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 after cooling its personal medium (might be understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, don't just the pump head element ought to be cooled, but also the suspension bearing chamber must be Geared up by using a stamping pump cooling system. The pump construction is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows variety, but the cost is superior ( The value is in excess of ten times that of a normal machine seal).
