How to select a circulation pump for superheated water in manufacturing processes?
Thread Content
Dear Haihao friends: I am working on a hot water circulation system that uses pressurized hot water at 110 degrees Celsius； To create a relatively insulated circulation within a system, how should the circulation pump be selected for optimal performance? Thank you.
110°C is not considered too high either; a high-temperature centrifugal pump will suffice, and Plan23 can be used for seal flushing.
Fos, Morui, and Aitiiti all have hot water pumps; there are also domestic ones, so just provide them with the specifications.
The temperature isn’t too high, so domestic heat-resistant water pumps will work just fine
Reply to 4# hghbxy: The answer above is based on the situation where the positive pressure at the inlet is high (at least 0.3 MPa or more); only in such cases can one follow their recommendations. Of course, this is a good option. However, if the inlet pressure is low, then the cavitation margin of the device must be taken into consideration. The cavitation margin required for the pump is low; it depends on specific parameters.
