CIRCOR’S German entity ALLWEILER received big pump order to be installed in BILFINGER ENGINEERING & TECHNOLOGIES’ (BET) exhaust gas cleaning system for ships.

High-performance ALLHEAT® pumps from Allweiler® are essential for moving heat transfer oils in many of their production processes. Top priorities in selecting a pump are the safety of employees and systems, system availability, and a low total cost of ownership.

PWT was the project manager for this plant, designing and operating it since its completion in mid-2012, under contract from Istanbul’s Water and Wastewater Company (ISKI). Argus Makine, the Istanbul-based representative of ® the German pump manufacturer Allweiler , a brand of

Colfax Fluid Handling offers stators made of "Alldur®" in progressing cavity pumps manufactured by Allweiler in Bottrop, Germany. These pumps have been used for decades in a variety of applications, including many sweage plants in Germany and other countries. They are characterized by their ability to easily pump liquids with a large proportion of dry substance and abrasive components. A variety of available designs and materials enable adaption of the pumps to specific liquids and pumping conditions. Now, with stators made of "Alldur®", they are even more economical.

In 2005 the company embarked on a comprehensive renovation of its entire infrastructure, including the network of pumps and 70 km of piping. The system takes advantage of the discharge pressure of the oil wells to pump the oil/water/gas mixture through new pipelines to the centralized Matzen extraction station. Thirty-one pumps from Colfax brand Allweiler replaced pumps from a variety of manufacturers in the individual stations. The tank farm as well uses large screw pumps ("SMH“ series) from this manufacturer for all qualities of crude oil.

To deal with this situation, engineer Peter Sikora organized a team to develop a process-based alternative to biological elimination of nitrogen. The pumps moving filtration water into the nitrogen elimination plant are a critical aspect of the concept. In 2006, the plant began using Allweiler peristaltic pumps as an alternative to the centrifugal pumps from another manufacturer.

Flender AG, a subsidiary of Siemens AG, has been using screw pumps from Allweiler AG for more than 25 years. Flender’s plant in Voerde, Germany (in the industrialized Ruhr region) manufactures gear units for extruder systems and vertical mills. The pumps supply the gear units with oil that is needed both for lubrication and for cooling. Large vertical mills require as much as 2000 l/min in order to achieve the required cooling capacity of 400 to 500 kW. In extruder gear units, pump capacity is usually 1200 l/min and cooling capacity is approximately 600 kW.

Progressing cavity pumps reflect an established design with decades of usage in many industries and applications. Production of biodiesel and biogas is a relatively new application where progressing cavity pumps are increasingly utilized. In the past several years, Allweiler AG has supplied pumps for a large number of biodiesel plants. In addition to fulfilling the two requirements mentioned above, this manufacturer has another major advantage: it produces its stators in-house at its own plant. This allows them to select from up to 20 different materials as needed, while also having the ability to produce stators in common dimensions and materials quickly and economically. These capabilities have proven to be extremely valuable for serving the German-Austrian firm PPM GmbH.

ALLWEILER AG’s Bottrop plant specializes in manufacturing progressing cavity pumps and peristaltic pumps. These products are capable of pumping virtually any liquid, including those that are chemically aggressive or mechanically abrasive. They can even handle fibrous additives during continuous operation. ALLWEILER pumps ensure long maintenance intervals, minimal production interruptions, and a low Total Cost of Ownership. Marchfelder BioEnergie GmbH uses ALLWEILER pumps in the production of biogas from organic waste.

Progressing cavity pumps from Allweiler AG have been standard equipment in food and beverage production for many decades.Mera Tiernahrung GmbH, a German pet food manufacturer, selected these pumps in 2004 for use in a new plant. They had had good experiences with progressing cavity pumps in their old plant, and their plant builder was also quick to recommend them. Mera uses a variety of plant and animal-based raw materials to produce high-quality dog and cat food at their highly advanced production plant. The company""s motto is "Five stars for four legs".

The Chemische Fabrik Budenheim KG (CFB) (Chemical Factory Budenheim) produces precursors and ingredients for a wide range of a variety of final products. CFB has developed its own solutions and processes in order to crystallize various phosphates and to dry it afterwards. In this process the pumps play a central role in pumping the crystal mush from the preparation tanks into the rotary pipe, and with that, for further processing. The crystal mush is highly abrasive, very viscous and in part very hot. In the food and beverages industry progressing cavity pumps from Allweiler AG have for decades been part of the standard production equipment.

"Years of reliability is our first priority," according to engineer Albert Feisst, the director of liquid engineering who is responsible for all pumps used in Herrenknecht AG tunnel boring machines. Headquartered in southwest Germany, Herrenknecht is a global market leader in its industry. For more than 30 years, pumps from Allweiler AG have played a key role in these machines. Some tunnel boring machines are the size of a house and contain nearly every type of pump manufactured by Allweiler AG.

The heart of the power plants are thermal oil pumps from Allweiler AG, a pump manufacturer based in Radolfzell, Germany . These pumps feed hot oil at temperatures up to 350 °C into a heat exchanger where the silicon oil is heated to the point of vaporization. Having centralized thermal oil pumps that are safe and dependable is critical for maintaining reliable energy production.

A major business segment at Hermann Bantleon GmbH is the development, production, and sales of lubricants. At its plant in Ulm, Germany, this company starts with high-quality base oils and produces both universal and customized lubricants according to its own formulas. Customized products are often the best way to meet special requirements in cutting and non-cutting production processes. Pumps of several different types and sizes play a major role in the manufacturing processes at Bantleon. For nearly 30 years, this company has relied on Allweiler AG of Radolfzell, Germany for the pumps it needs.

As environmental regulations become more stringent, waste gas treatment systems are growing in importance. H+H Umwelt- und Industrietechnik GmbH of central Germany has been using Allweiler progressing cavity pumps as a core component of these systems since 2003. The company has been manufacturing catalytic waste gas treatment systems since 1998.

In May 2010 the Gubin sewage plant celebrated its twelf-year anniversary. This plant processes wastewater from the cities Guben and Gubin, located on opposite sides of the Neisse River. It is the only German-Polish project of this type to operate successfully for the long term. Major elements of the plant include 17 progressing cavity pumps and two macerators from Allweiler AG.
