The transportation of high-temperature medium places larger needs around the composition, resources and auxiliary program of the pump. Let us speak about the cooling prerequisites of various temperature changes and the corporation's applicable pump style:
1. For media with a temperature decrease than 120°C, there is frequently no Unique cooling procedure, as well as the medium alone is utilized for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety volume of shielded motor ought to exceed H quality when over 90°C); and DFCZ popular sort and IH chemical pump can use temperature to undertake suspension structure The upper Restrict is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be employed as much as two hundred°C; only CQB standard magnetic pump use temperature doesn't exceed one hundred°C. It is actually well worth mentioning which the medium that click here is easy to crystallize or is made up of particles need to be equipped by using a sealing area flushing line (designed using an interface).
two. For mediums higher than 120°C and beneath three hundred°C, a cooling chamber shall be furnished on the pump go over. The sealing chamber shall even be linked to the coolant (with double mechanical seal), in the event the coolant is not allowed to penetrate in to the medium. It should be taken immediately after cooling its have medium (may be realized by basic warmth exchanger).
three. For top temperature medium higher than three hundred°C, not only the pump head component has to be cooled, but in addition the suspension bearing chamber really should be Geared up which has a cooling system. The pump structure is generally in the form of a central support. The mechanical seal is preferably a metal bellows type, but the price is higher ( The price is greater than 10 occasions that of a normal machine seal).
