The transportation of high-temperature medium puts greater specifications on the framework, components and auxiliary system with the pump. Let's talk about the cooling necessities of different temperature variations and the business's applicable pump form:
1. For media that has a temperature reduce than a hundred and twenty°C, there is normally no special cooling technique, and the medium by itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection amount of shielded motor really should exceed H grade when in excess of ninety°C); and DFCZ frequent style and IH chemical pump can use temperature to adopt suspension framework The higher limit is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized as many as 200°C; only CQB regular magnetic pump use temperature would not exceed 100°C. It truly is worth mentioning that the medium that is a snap to crystallize or contains particles must be Geared up with a sealing surface area flushing line (intended having an interface).
2. For mediums previously get more info mentioned one hundred twenty°C and down below 300°C, a cooling chamber shall be offered about the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), once the coolant is just not permitted to penetrate into your medium. It should be taken following cooling its possess medium (is often understood by simple heat exchanger).
3. For high temperature medium previously mentioned 300°C, not simply the pump head aspect really should be cooled, but also the suspension bearing chamber ought to be Outfitted using a cooling technique. The pump framework is mostly in the shape of the central guidance. The mechanical seal is if possible a metallic bellows form, but the worth is higher ( The value is over 10 instances that of a standard machine seal).
