The transportation of high-temperature medium places higher specifications around the structure, materials and auxiliary method of the pump. Let us take a look at the cooling requirements of various temperature variations and the corporation's relevant pump sort:
1. For media with a temperature lessen 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 (security standard of shielded motor need to exceed H grade when about 90°C); and DFCZ common style and IH chemical pump can use temperature to adopt suspension composition The higher limit 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 needs to be Geared up using a sealing area flushing line (created with an interface).
2. For mediums higher than 120°C and underneath 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), once the coolant will not be 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 merely the pump head aspect needs to be cooled, but in addition the suspension bearing chamber really should be equipped using a cooling technique. The pump composition is generally in the form of a central help. The mechanical seal is ideally a stamping pump metallic bellows type, but the price is large ( The cost is in excess of ten times that of a normal machine seal).
