The transportation of superior-temperature medium places better prerequisites on the composition, products and auxiliary procedure with the pump. Let us mention the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature reduce than a hundred and twenty°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include 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 prevalent sort 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 website of particles ought to be Geared up having a sealing floor flushing line (developed having an interface).
2. For mediums earlier mentioned 120°C and underneath three hundred°C, a cooling chamber shall be offered on the pump go over. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant is not really allowed to penetrate in the medium. It ought to be taken right after cooling its possess medium (might be understood by easy warmth exchanger).
three. For high temperature medium over three hundred°C, don't just the pump head component ought to be cooled, but also the suspension bearing chamber needs to be Geared up which has a cooling method. The pump framework is mostly in the shape of the 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 normal machine seal).
