The transportation of substantial-temperature medium puts larger demands to the framework, resources and auxiliary process on the pump. Let's speak about the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature reduce than a hundred and twenty°C, there is frequently no Exclusive cooling technique, as well as the medium itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical style and IH chemical pump can use temperature to adopt suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately 200°C; only CQB standard magnetic pump use check here temperature will not exceed a hundred°C. It truly is really worth mentioning which the medium that is straightforward to crystallize or contains particles must be equipped by using a sealing surface flushing line (made with an interface).
two. For mediums above one hundred twenty°C and down below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), in the event the coolant isn't permitted to penetrate into the medium. It should be taken immediately after cooling its personal medium (might be understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element ought to be cooled, but also the suspension bearing chamber needs to be Geared up by using a cooling procedure. The pump structure is usually in the form of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The worth is greater than 10 moments that of a standard equipment seal).
