The transportation of substantial-temperature medium places greater demands about the framework, resources and auxiliary procedure with the pump. Let us look at the cooling demands of different temperature modifications and the business's applicable pump sort:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling program, and also the medium alone is employed 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 structure The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used as many as 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning the medium that is simple to crystallize or incorporates particles must check here be equipped by using a sealing surface flushing line (built using an interface).
two. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be offered on the pump protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant isn't allowed to penetrate into your medium. It should be taken just after cooling its very own medium (can be realized by very simple heat exchanger).
three. For high temperature medium earlier mentioned 300°C, not simply the pump head portion needs to be cooled, but in addition the suspension bearing chamber really should be equipped by using a cooling procedure. The pump construction is mostly in the shape of the central assistance. The mechanical seal is ideally a steel bellows form, but the worth is higher ( The cost is over ten situations that of a normal machine seal).
