The transportation of significant-temperature medium places better prerequisites on the structure, materials and auxiliary system of your pump. Let us look at the cooling necessities of different temperature adjustments and the organization's applicable pump type:
1. For media which has a temperature decreased than one hundred twenty°C, there is usually no Specific cooling program, and also the medium itself is used for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security level of shielded motor must exceed H quality when around ninety°C); and DFCZ popular sort and IH chemical pump can use temperature to undertake suspension structure The higher limit is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be employed as much as two hundred°C; only CQB common magnetic pump use temperature isn't going to exceed one hundred°C. It can be worthy of mentioning the medium that is a snap to crystallize or has particles really should be Outfitted having a sealing surface flushing line (designed by having an interface).
2. For mediums above a hundred and twenty°C and under 300°C, a cooling chamber shall be furnished over the pump include. The sealing chamber shall even be connected to the coolant (with double mechanical seal), once the coolant is not permitted to penetrate into your medium. It ought to be taken just after check here cooling its have medium (is often recognized by basic heat exchanger).
three. For prime temperature medium above three hundred°C, not just the pump head component has to be cooled, but also the suspension bearing chamber need to be Geared up that has a cooling method. The pump construction is generally in the shape of a central aid. The mechanical seal is preferably a metallic bellows variety, but the price is significant ( The price is much more than 10 times that of a traditional device seal).
