The transportation of superior-temperature medium places bigger prerequisites on the composition, products and auxiliary procedure of your pump. Let us speak about the cooling demands of different temperature modifications and the organization's relevant pump form:
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 volume of shielded motor really should exceed H grade when over ninety°C); and DFCZ typical type and IH chemical pump can use temperature to undertake 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 will not exceed 100°C. It truly is really worth mentioning which the medium that is straightforward to crystallize or contains particles really should be equipped 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 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 just 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 ought to be cooled, but also the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. double suction pump The mechanical seal is ideally a steel bellows form, but the worth is higher ( The value is a lot more than ten situations that of a traditional machine seal).
