Even with low water levels and high-temperature liquid, we want to suppress cavitation with a land-based horizontal pump!
Since aluminum electrolytic capacitors are directly related to the safety and quality of automobiles, there is a demand for further improvement in their performance and quality. In the manufacturing equipment for aluminum electrolytic capacitors, vertical axis pumps of the tank type are used for transferring electrolyte liquid close to its boiling point (95°C). However, in the new product manufacturing process, the electrolyte liquid becomes even hotter, and it was found in internal tests by users that the existing pumps could not meet the required suction performance of NPSH.Av1.3m or higher, leading to cavitation. We received a consultation from users who wanted to consider a maintenance-friendly horizontal land pump that would not cause cavitation, instead of a tank-type pump. [Case Study] ■ Site: Aluminum electrolytic capacitor manufacturing factory ■ Challenge - To suppress cavitation even with high-temperature liquid at low water levels using a horizontal land pump ■ Proposal - Introduction of a low NPSH stainless steel vortex pump, MAP type ■ Effect - Achieved stable transfer of high-temperature liquid and reduction of initial and running costs *For more details, please refer to the PDF document or feel free to contact us.
