The transportation of substantial-temperature medium puts better prerequisites on the composition, materials and auxiliary system of your pump. Let us look at the cooling demands of different 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 degree of shielded motor should exceed H quality when above 90°C); and DFCZ prevalent sort and IH chemical pump can use temperature to adopt 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 includes particles should be Outfitted with a sealing floor flushing line (designed by having an interface).
2. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be supplied within the pump cover. The sealing chamber shall also be linked to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its very own medium (is usually realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not only the pump head element really should be cooled, but additionally the suspension read more bearing chamber must be Geared up with a cooling program. The pump composition is generally in the form of a central assist. The mechanical seal is ideally a metallic bellows type, but the price is large ( The cost is much more than ten times that of a normal machine seal).
