The transportation of significant-temperature medium places higher needs within the construction, components and auxiliary technique in the pump. Let's discuss the cooling specifications of different temperature variations and the corporation's relevant pump variety:
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. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical style 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 standard magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning that the medium that is simple to crystallize or incorporates particles must be Geared up 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 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 (is often understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element really should be cooled, but additionally the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is generally in the form of a central assist. The more info mechanical seal is if possible a metallic bellows type, but the value is substantial ( The worth is more than 10 occasions that of a standard device seal).
