The transportation of higher-temperature medium puts greater needs about the framework, resources and auxiliary process with the pump. Let us mention the cooling demands of different temperature modifications and the company's relevant pump kind:
one. For media with 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 standard of shielded motor need to exceed H grade when around 90°C); and DFCZ common style and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ 160°C; IHF lining fluorine pump may be used around two hundred°C; only CQB regular magnetic pump use temperature does not exceed one hundred°C. It's truly worth mentioning the medium that is easy to crystallize or is made up of particles ought to be Outfitted having a sealing floor flushing line (developed by having an interface).
2. For mediums earlier mentioned 120°C and underneath 300°C, a cooling chamber shall be presented on the pump protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), once the coolant is not really allowed to penetrate in the medium. It ought to be taken right after cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than read more 300°C, not just the pump head aspect needs to be cooled, but in addition the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is normally in the form of a central help. The mechanical seal is ideally a steel bellows style, but the price is large ( The value is in excess of ten times that of a normal machine seal).
