The transportation of superior-temperature medium places better needs over the construction, products and auxiliary program of your pump. Let's mention the cooling requirements of different temperature variations and the business's relevant pump type:
1. For media that has a temperature reduce than one hundred twenty°C, there will likely be no Unique cooling process, and the medium itself is employed for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection amount of shielded motor really should exceed H grade when more than 90°C); and DFCZ prevalent type and IH chemical pump can use temperature to adopt suspension construction The higher Restrict is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be utilized approximately two hundred°C; only CQB everyday magnetic pump use temperature does not exceed 100°C. It truly is worthy of mentioning which the medium that is easy to crystallize or includes particles must be Outfitted which has a sealing area flushing line (designed with the interface).
2. For mediums over one hundred twenty°C and under three hundred°C, a cooling chamber shall be furnished to the pump deal with. The sealing chamber shall even be linked to the coolant (with double mechanical seal), in the event the coolant is not really permitted to penetrate into the medium. It ought to be taken after cooling its personal medium (may be realized by easy heat exchanger).
3. For top temperature medium above three hundred°C, don't just the pump head section really should be cooled, but will also the suspension bearing chamber should be Geared up which has a cooling procedure. The pump composition is mostly in the shape of a central assistance. The mechanical seal is preferably a metal bellows style, but the worth is significant ( here The cost is a lot more than 10 occasions that of a normal equipment seal).
