Tremendous Savings On Board

speed control of seawater cooling pumps brings tremendous potential for savings to Hapag-Lloyd AG


As shipping rates drop and competitive pressures increase, shipowners are under tremendous pressure to reduce the operating costs of their vessels. Fuel is still the number-one factor for savings, even with today's lower fuel prices.. And because seawater cooling pumps are larger than required for slow steaming, shipowners will require even more fuel than they need with conventional pump control systems (only valves).

Workhorse Pumps

Keep Ipsen furnaces humming 20 years after initial installation


The reputation of manufacturers rides on the performance of their products. So to ensure the best quality for customers, they demand that the parts that go into their products must be reliable and work flawlessly.


That has certainly been the challenge for Ipsen International GmbH of northwestern Germany, the market leader in the manufacture of high-temperature furnaces. Today, Ipsen has installed more than 20,000 of these systems around the world. But in 1993, when Ipsen began building these systems, they were challenged with finding suitable pumps for these high-temperature furnaces.



Demanding challenges met

by Allweiler® Pumps at Used-Oil Transfer


Puralube Germany GmbH operates two refineries according to the innovative UOP HyLube process. Total throughput is 150,000 metric tons per year with used oil as feedstock. The plants are located in the Zeitz industrial park, approximately 40 km south of Leipzig, Germany. Since beginning production at the world's first refinery of this type in mid-2004, the Zeitz site has been producing high-quality API Group II and III base oils. In late 2008, a second plant was brought on line at the same location. Each year, the two plants consume approximately 150,000 metric tons of feedstock. They produce about 90,000 metric tons of base oils and another 50,000 metric tons of other mineral oil products. Currently approximately 110 employees work in production, quality assurance, sales, and administration at this location.



Progressing cavity pumps at the Heimbach power plant


The operating principles and overall design of progressing cavity pumps make them suitable for universal use. One of their fields of application is the pumping of abrasive liquids that may contain solids, but also fibers. Sludges in sewage plants are one example. These pumps are also well-suited to metering. They generate a consistent and pulsation-free flow even when faced with fluctuating working pressures and liquid consistencies. Gentle pumping action, with low turbulence and minimal mixing of the pumped liquid, is another identifying characteristic of progressing cavity pumps.



Pumps from Colfax Fluid Handling

in Istanbul`s largest modern sewage plant


The metropolitan region of Istanbul currently has 15 sewage treatment plants serving nearly 20 million residents. The largest plant is located in Ambarli and is also one of the most modern and largest sewage treatment plants in Europe. German water and wastewater engineering firm
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, handles maintenance and optimization of all pumps in the plant. Colfax Fluid Handling is a business of Colfax  Corporation (NYSE: CFX).



High-Performance Pumps from Colfax Fluid Handling

Pumping dewatered sludge across 70 M (230 FT)


The Hurma municipal sewage treatment plant near Antalya, Turkey is notable for several reasons. Its approach to sludge clarification, drying, and reprocessing, as well as the associated generation of heat and power, is unique in Turkey. Secondly, only a small number of plants use a
progressing cavity pump to move sludge to a dryer across such a long distance (70 m/230 feet).



Frequency-controlled pumps from Colfax Fluid Handling in machine tools


Pump applications for machine tools must fulfill special requirements in order to ensure efficent tooling changes. The pumps must supply each tool with cooling lubricant or cutting oil as soon as the tool has been engaged. Fluid volume and pressure requirements vary for each tool.

Rather than pumping excess coolants and lubricants in a loop, intelligent controllers adjust pump speeds to the precise volume and pressure. Smaller pumps and motors can be utilized, proving equipment savings as well.



Colfax CM-1000 "Smart Tech" for Efficient Sea Water Cooling Pumps


Colfax introduced earlier this year the CM-1000 Series, a smart technology designed to help monitor and control sea water cooling system pumps in a manner that senses water temperature and speed to optimize the pump use.

Savings for the shipowner come not only via fuel used to power the pumps (in some cases, up to 80% in fuel consumption reduction and 50% in maintenance cost reduction have been recorded), but also the benefit is an appreciable reduction of wear and tear on pump parts and maintenance.



Revolutionary Materials - Result in Long-Lasting Stators


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.



Crude Oil Pumps from Colfax Fluid Handling


OMV Austria Exploration & Production GmbH and its predecessors have been pumping crude oil in Vienna''s wine growing region for more than 50 years. Approximately 600 oil wells make up Austria''s Matzen oilfield. They pump an oil/gas/water mixture (approx. 90% water) through pipelines to a centralized live oil collection station.

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.

Monitoring vibrations, mechanical seals, and bearings for safety and performance


With more than 70 years of experience in plastics processing, Switzerland-based Quadrant Group is a leading expert in a wide range of polymer materials and technologies for polymer conversion. In order to maintain a high level of quality in the production process, Quadrant''s heat-transfer pumps must work safely and reliably. These pumps are commonly subjected to high loads. At the same time, failure of a pump can have serious consequences, especially if hot oil escapes. The high loads on the pump are the result of high temperatures and large temperature differentials as well as decomposition reactions that may occur when the heat transfer liquid is subjected to excessive thermal loads.



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. When compared to petroleum-based heat-transfer oils, the amount of maintenance associated with synthetic oils is significantly lower.



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.

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.

Problem-free pumping of crystal mush with Allweiler progressing cavity pumps  


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.



Pumps for bitumen and wax   


Moving and processing petroleum-based products involves special challenges. Pumps used in this activity must be capable of moving liquids that have very good lubricating properties as well as liquids containing abrasive components. Depending on the particular process step, high discharge pressure or high capacity may be needed. Finally, viscosity of the pumped liquid can vary from finished, flowing petroleum products to highly viscous liquids like bitumen. 

At Nyrosten Korrosionsschutzmittel GmbH & Co. of western Germany, Allweiler’s screw pumps have been in continuous service for decades.



Pumps used during tunnel construction: Long service life is crucial   


"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.
