The transportation of superior-temperature medium places bigger requirements on the composition, materials and auxiliary system of your pump. Let us look at the cooling necessities of various temperature adjustments and the business's applicable pump type:
one. For media that has a temperature decrease than one hundred twenty°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 amount of shielded motor ought to exceed H quality when in excess of 90°C); and DFCZ popular variety and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump may be used as much as two hundred°C; only CQB everyday magnetic pump use temperature will not exceed a hundred°C. It is value mentioning which the medium that is straightforward to crystallize or has particles should be Outfitted that has a sealing surface flushing line (created by having an interface).
two. For mediums above one hundred twenty°C and underneath three hundred°C, a cooling chamber shall be supplied within the pump deal with. The sealing chamber shall even be connected to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate into your medium. It should be taken following cooling its possess medium (is often understood by simple heat exchanger).
3. For high temperature medium previously mentioned three hundred°C, not simply the pump head section needs to be cooled, but additionally the suspension bearing chamber needs to be Outfitted check here that has a cooling procedure. The pump composition is normally in the shape of the central support. The mechanical seal is preferably a metallic bellows sort, but the cost is superior ( The price is over 10 moments that of a normal device seal).
