The transportation of higher-temperature medium places greater needs within the construction, supplies and auxiliary method from the pump. Let's take a look at the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
one. For media that has a temperature decrease than one hundred twenty°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor should exceed H quality when above ninety°C); and DFCZ prevalent sort and IH chemical pump can use temperature to undertake suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump may be used as much as two hundred°C; only CQB regular magnetic pump use temperature does not exceed one hundred°C. It's truly worth mentioning that the medium that is easy to crystallize or is made up of particles ought to be Geared up having a sealing floor flushing line (developed by having here an interface).
2. For mediums earlier mentioned 120°C and under three hundred°C, a cooling chamber shall be offered over the pump go over. The sealing chamber shall even be connected to the coolant (with double mechanical seal), once the coolant is not really allowed to penetrate to the medium. It ought to be taken following cooling its individual medium (can be recognized by uncomplicated heat exchanger).
3. For prime temperature medium higher than 300°C, not just the pump head aspect needs to be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the price is substantial ( The cost is much more than ten instances that of a standard device seal).
