The transportation of significant-temperature medium places bigger prerequisites on the composition, products and auxiliary procedure from the pump. Let us take a look at the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
one. For media which has a temperature decreased than one hundred twenty°C, there is normally no Unique cooling system, as well as medium by itself is utilized for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security 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 ~ 160°C; IHF lining fluorine pump may be used around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It's truly worth mentioning 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 above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be linked to the coolant (with double mechanical seal), in the event the coolant just isn't permitted to penetrate into the medium. It should be taken immediately after cooling its personal medium (is often realized by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element really should be cooled, but additionally the suspension check here bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central help. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is in excess of ten times that of a normal machine seal).
