The transportation of higher-temperature medium puts greater needs within the construction, resources and auxiliary technique on the pump. Let's discuss the cooling specifications of various temperature variations and the corporation's relevant pump variety:
1. For media with a temperature lower than a hundred and twenty°C, there is often no Particular cooling method, and the medium alone is employed for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection standard of shielded motor need to exceed H quality when about 90°C); and DFCZ common form 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 can be employed around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It really is worth mentioning 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).
2. For mediums higher than one hundred twenty°C and below three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its possess medium (is usually realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion really should be cooled, but additionally the suspension bearing chamber really should be Geared up which has a cooling method. The pump framework is mostly in the shape of the central assistance. The mechanical seal is preferably a steel bellows form, but mixed flow pump the worth is high ( The value is a lot more than ten periods that of a traditional machine seal).
