The transportation of superior-temperature medium places better prerequisites on the composition, products and auxiliary system of your pump. Let us look at the cooling necessities of different temperature adjustments and the organization's applicable pump sort:
1. For media which has a temperature lessen than one hundred twenty°C, there is often no Unique cooling system, as well as medium by itself is utilized for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security amount of shielded motor ought to exceed H quality when in excess of 90°C); and DFCZ popular variety and IH chemical pump can use temperature to adopt 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 is worthy of mentioning that the medium that is not hard to crystallize or is made up of particles ought to be Geared up having a sealing floor flushing line (developed by having 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 click here chamber shall even be linked to the coolant (with double mechanical seal), once the coolant will not be allowed to penetrate in the medium. It ought to be taken right after cooling its have medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must 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 large ( The cost is much more than ten times that of a normal machine seal).
