Due to automation, changing from one coating to another is no longer a time consuming task. Users of KBA sheetfed presses can choose between Harris & Bruno's single line pumping system or Tresu's dual line system. Since KBA has found in the tests that the results obtained by the two systems are basically the same, the level of automation and the input involved in manual operations have changed, so their advantages and basic principles are also different. At the end of each shift and...

One of the most important issues in multi-stage pump assembly is to check that the center of the impeller exit is the same as the center of the guide (deflector) inlet. That is, each impeller exit center must be aligned with the center of the guide wing inlet. Adjusting the "center of consistency" not only ensures the normal efficiency of the pump, but also to prevent the rotation, or impeller and other hazards before and after touch. The center of the "center" is mainly determined by the...
