Editorial 3 Ladies and Gentlemen Several years ago in the sera news editorial I quoted the Greek statesman Pericles (around 495-429 B.C.): ”It is not important to predict the future, but to be prepared for the future.“ My intention was to point out that one cannot predict the future but must actively shape it. The effects of the worldwide financial and economic crisis now make this strikingly obvious. sera was also put to the test by these developments but has been able to master them quite well so far, due to the many internal improvements in the company over the past years, accompanied by the...

sera customers are satisfied customers! 5 A summary of results from the large-scale 2010 customer survey In the spring of 2010, sera conducted a worldwide customer satisfaction survey. One of the objectives of this survey was to ascertain whether sera’s corporate philosophy, i.e. to always focus on the customers with their individual requests, and the scope of services offered by sera, were actually appreciated by the customers. A high response rate within a short amount of time was the first positive surprise. This showed us that the customers also thought it was important to take time for sera...

Always up-to-date for our customers 6 The implementation of European directives at sera The implementation of European directives is generally very demanding for businesses. The associated effort for the individual company is very high, but it pays off in the long run as it leads to significant improvements in the innovation process of the products. At the same time, the company ensures that the customers can always rely on acquiring products that conform with the latest legal directives. The objectives of the European guidelines include: The determination of basic objectives, for example, the...

The sure answer to high counterpressure 7 The newly engineered lifting gears of the 510.1 and 511.1 model series, designed as adjustable eccentric gear units, are the basis of this new model series. Adjustable eccentric gear units for precise dosing with high delivery rates and high pressures The adjustable eccentric gear unit permits linear and precise stroke length adjustment and thus highly precise dosing. The optimised motion sequence, even with partial stroke operation, results in a reduction of wear and noise compared to conventional lifting gears, especially with higher delivery rates...

8 Because of the benefits outlined above the sera piston diaphragm pump is suitable for a very large range of applications. This encompasses dosing tasks in the food industry to applications in pharmaceuticals or petrochemicals. Optionally also available with ATEX approval or API 675 conformity To permit their use in crude oil pumping and processing, these pumps will optionally be available for explosion-protected areas as well as for the API Standard 675. The latter is especially made possible through the form-fitting connection of the individual components. Comprehensive accessories complete...

9 The new C410.2ML with PROFIBUS interface sera C410.2ML with Profibus interface Process reliability redefined with improved communication capabilities Based on the proven diaphragm pump model series 410.2, sera now also offers multi-layer diaphragm pumps with the proven integrated sera control electronics (C series). For operating pressures in the range of up to 16 bar, sera can thus offer solutions for performance ranges between 70 l/h and 1,200 l/h. The scope of applications for the multi-layer diaphragm pumps ranges from the chemical, petrochemical and pharmaceutical industry (e.g. for the...

10 sera dosing technology for the CIP cleaning processes at R&R Ice Cream Communication via Profibus DP The multifunctionally selectable C410.2ML pumps are optionally available with PROFIBUS DP interface (slave). The PROFIBUS DP interface replaces the conventional selection options via analogue or contact signal, permits the straightforward integration of the dosing pumps in complex systems of the process industry and reduces the wiring effort required. R&R Ice Cream developed from the merging of Roncadin in Germany and Richmond Ice Cream in Great Britain and is one of Europe’s largest ice cream...

11 Four sera DAV 75. 1 units provide for the highly accurate dosing of disinfectants, soda lye and nitric acid in the CIP process The cleaning processes are performed according to so-called CIP recipes. There are eight recipes for 230 objects altogether. Example for a recipe: Hot water (40 °C), pre-rinsing without chemicals 1% soda lye (increase to 5% quantity-proportional subsequent regeneration) Intermediate rinse Nitric acid Subsequent rinsing with cold fresh water Discharge (extracting the system content with H2O) Disinfectant Subsequent rinsing to discharge disinfectant The dosing systems...
