The transportation of high-temperature medium places better prerequisites on the composition, products and auxiliary procedure of your pump. Let us mention the cooling demands of different temperature modifications and the company's relevant pump form:
1. For media having a temperature reduce than a hundred and twenty°C, there is frequently no Specific cooling system, and also the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around 90°C); and DFCZ common style and IH chemical pump can use temperature to adopt suspension structure 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 has particles needs to be Geared up using a sealing area flushing line (created having an interface).
2. For mediums higher than 120°C and underneath 300°C, a cooling chamber shall be presented on 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 (can be recognized by uncomplicated heat exchanger).
3. For high temperature medium previously mentioned three hundred°C, not only 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 assistance. The mechanical seal is ideally a steel bellows form, but the worth is higher ( The value is a lot more than ten situations that of a traditional machine more info seal).
