Pumps for synthetic heat-transfer liquids    

As soon as the temperature in a heat-transfer system becomes too high for water, a plant operator must choose between petroleum-based or synthetic oils as the heat-transfer liquid.  When modern petroleum oils are used, systems with feed temperatures up to about 300 °C can stay in service for their entire service life with one filling and with virtually no maintenance. Once feed temperatures rise above 300 °C, only high-quality synthetic oils will be appropriate. Under these conditions, even minor temperature increases will have a decisive effect on the service life of the oils. An additional 10 °C commonly doubles the product's specific rate of decomposition. 

Pumps are the heart of heat-transfer plants   

Manufacturers in a variety of industries depend on heat-transfer plants to heat or cool their machines and apparatus. German firm heat11 GmbH & Co. KG specializes in heat-transfer plants of virtually all types. The chemical industry uses their installations for controlling the temperature of reactors and during the production of color pigments and liquid crystals. In the plastics industry, heat-transfer plants are essential for producing polyethylene terephthalate (PET) and in the production of CDs and DVDs. But recently, according to heat11’s Managing Director Dietmar Hunold, heat recovery has become an increasingly important application. 

Peristaltic pumps for moving filtration water  

The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities.

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.

Temperature and leak monitoring boosts safety and reliability 

Amcor Flexibles Singen GmbH is a manufacturer of printed and unprinted aluminum-based packaging materials and an experienced technical applications specialist. High-performance drying equipment is essential for Amcor’s production process. Having centralized thermal oil pumps that operate safely and dependably is critical for the drying process.

Flexibility is key: Screw pumps in oil-supply systems  

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 for pumping chemically aggressive liquids during biodiesel production  

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.

Durable ALLWEILER pumps for biogas engineering  

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.
