The transportation of significant-temperature medium puts increased necessities to the composition, elements and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature modifications and the organization's applicable 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 nearly 200°C; only CQB everyday magnetic pump use temperature isn't here going to exceed 100°C. It can be well worth mentioning which the medium that is a snap to crystallize or consists of particles need to be Outfitted that has a sealing surface flushing line (intended with the interface).
two. 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 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 personal medium (might be understood by easy warmth exchanger).
three. For top temperature medium over three hundred°C, don't just the pump head component ought to be cooled, but also the suspension bearing chamber needs to be Outfitted which has a cooling method. The pump construction is mostly in the shape of the central support. The mechanical seal is preferably a steel bellows variety, but the worth is high ( The price is over ten periods that of a traditional equipment seal).
