The transportation of superior-temperature medium places higher necessities over the composition, elements and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature modifications and the organization's relevant pump style:
one. For media using a temperature reduce than 120°C, there will likely be 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 really should exceed H grade when over ninety°C); and DFCZ frequent type and IH chemical pump can use temperature to undertake suspension construction 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 really worth mentioning which the medium that is not difficult to crystallize or incorporates 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 furnished around the pump deal with. The click here sealing chamber shall also be connected to the coolant (with double mechanical seal), in the event the coolant isn't permitted to penetrate into your medium. It should be taken immediately after cooling its own medium (might be understood by easy heat exchanger).
three. For top temperature medium over 300°C, don't just the pump head component should be cooled, but will also the suspension bearing chamber ought to be Outfitted that has a cooling system. The pump construction is mostly in the shape of the central aid. The mechanical seal is preferably a metal bellows variety, but the cost is superior ( The price is over 10 moments that of a traditional equipment seal).
