The transportation of higher-temperature medium places higher specifications within the construction, components and auxiliary program in the pump. Let's talk about the cooling requirements of various temperature improvements and the corporate's applicable pump sort:
1. For media which has a temperature decreased than one hundred twenty°C, there is normally no Unique cooling system, as well as medium by itself is used for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense 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 one hundred forty°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 area flushing line (developed 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 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 (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head element really should be cooled, but additionally the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central help. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is in excess of ten situations that of here a normal machine seal).
