IN FOCUS

Operators looking for the most reliable, low-maintenance and efficient solution for discharging digested residual sludge at a sewage plant in Germany recently began a comparison of an inclined conveyor versus four-stage progressive cavity pumps.

It is always satisfying for a pump manufacturer to learn that its products have lived up to expectations after many years operation. For KSB Pumps Inc., Canada, this was the scenario when the City of Montreal approached them in 2013 to submit a tender for an additional pump set in order to expand its Charles-J.-Des Baillets drinking water production plant where five KSB ME type pumps had been operating since 1978.

Technology group Voith has won an order for the manufacture, supply and commissioning of two StreamDivers for the small hydropower plant Gradiste in Macedonia. The company will also supervise installation and supply the gate valves.

Even though Canaragua has installed dozens of SWRO plants throughout the Canary Islands, the project in Puerto de Mogán was unusual because of the focus on compactness.

Celje is the third largest city in Slovenia and sits at the junction of the Savinja, Hudinja, Ložnica, and Voglajna rivers in the lower Savinja Valley. Serving a population of 85,000 people, the city’s waste water treatment plant (WWTP) used two progressive cavity (PC) pumps to feed a centrifuge with settled sludge.

Elbphilharmonie in Hamburg draws thousands of Germans and tourists with an interest in culture. The new cultural centre in the HafenCity metropolis in northern Germany not only boasts top class cultural experiences – there are also hidden pump performers in the corridors.

In modern paper and cardboard production there are endless dosing tasks, for which precision and high reliability are especially critical. Mindful of these factors, European carton maker Moritz J Weig GmbH is increasingly turning to Qdos peristaltic pumps from Watson-Marlow Fluid Technology Group.

Voith was recently awarded two contracts in China. The first contract involves the supply of four pump turbine generator units for the Xiamen Pumped Storage Plant. The second order is for large-scale pumps for the Wan Jia Zhai project, aiming to expand the existing water supply network in Bejing.

A number of Bredel pumps from Watson-Marlow Fluid Technology Group (WMFTG) are proving highly successful in the circulation and transfer of waste return slurry from concrete slab manufacturing processes.

How precisely silane can be metered during continuous plastics processing has a direct influence on the quality of the end product. This is why fast and precise control of the flow rate must always be guaranteed – even when different types of silane are being used for different products. LEWA GmbH has a customer that faced this very challenge.
