The development of intensive shrimp farming business in the last decades has created a need to design special features for seawater pumping. High water demand, extreme corrosion due to salt water, and unstable terrain conditions to place civil works are just some of the design challenges for ETEC engineers.

Dieter Klefoth and Stefan Seemer look at a demand-based speed-controlled pump system. This, with new submersible pumps together with state-of-the-art control systems, has been instrumental in lowering the power consumption and raising the reliability and quality of a copper wire manufacturing process in Germany.

Torrential rain waterlogged building works at a road in Prague, causing a deep crater to appear. A pump solution was needed which could deal with the emergency situation. Two vacuum assisted self-priming pumps were deployed to clear the excess water, and deal with the slurry created during the drainage process.

The pumps in a Scottish distillery were struggling to cope with the abrasive lime used for dosing. A peristaltic hose pump was selected for its abrasion resistance and ability to ensure the smooth passage of the liquid, regardless of its viscosity. Since its installation, costs and downtime have decreased.

The use of seawater for all of Gibraltar’s flushing needs is both economical and problematic. The Waterport pumping facility required a system which could cope with salt water corrosion and the heavy rag and solids in the wastewater. A solution was found which provides reliable service and brings significant cost-savings.

When archaeologists discovered a haul of 16th century shipwrecks at a Norwegian building site, they realised that quick and efficient drainage had to be attempted to ensure both safe examination of the ships and timely completion of the building. A range of Tsurumi drainage pumps provided the answer.

A new CFdesign module, which facilitates carrying out multi-scenario design studies, has allowed Cornell Pump to spend more time on pump design, and much less time on expensive rework. CFD allows reliable simulation and optimization of the design, placement and performance of critical components, as this article shows.
