Description

<p>In Pulp and Paper process various type of pumps are using for from Digester application, Paper Machine application to Waste water application, including so called Water pump, Pulp slurry pump, Quantitative chemical pump. However, the majority of operation in use might be just Centrifugal process pumps than some specialized pump. There should be some specialties of technology depending on pump manufactures, of course. It may be able to say that the pump is exactly “The heart of your process” in the sense of functionality in your process as of pumping liquid. I am pleased to introduce basic issues and some application of centrifugal pumps including our process pumps made by Sulzer Pumps.</p><p>Then we get onto the points what is better to take into consideration at the suction area, such as NPSH and Cavitation. We also explain in the latter half of paragraph that pressure loss in the piping, and the advisable piping layout especially for pulp pumping. We also mention here about the performance change led by the difference of impeller diameter and speed. At the first paragraph, we hereby explain about the discharge function of pump generated by centrifugal force.</p><p>In the end we introduce pump selection guide for various application in pulp & paper industry process, and then the material selection of pump as well.</p><p>This is last but not least, we introduce here cutting edge of technology of Sulzer pumps.</p>
