The transportation of substantial-temperature medium puts increased necessities to the framework, elements and auxiliary process with the pump. Let us speak about the cooling needs of different temperature modifications and the company's relevant pump style:
one. For media using a temperature reduced than 120°C, there will likely be 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 really should exceed H grade when over ninety°C); and DFCZ frequent 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 utilized nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed one hundred°C. It is value mentioning that the medium that is simple to crystallize or has particles needs to be Geared up using a sealing area flushing line (made with an interface).
2. For mediums higher than one hundred twenty°C read more 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), if the coolant isn't permitted to penetrate into your medium. It should be taken soon after cooling its own medium (might be understood by easy heat exchanger).
three. For top temperature medium over 300°C, don't just the pump head component should be cooled, but will also the suspension bearing chamber ought to be Geared up using a cooling process. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is more than 10 instances that of a standard device seal).
