Lewa: Follow-up order of another 20 pumps to Saudi Arabia

Thursday, December 14th, 2017 von admin

Lewa delivered 40 process diaphragm pumps to two large offshore platforms on the Persian Gulf in 2013. Lewa has got now a follow-up order to this 30 Mio Euro order – the largest in the history of Lewa. The follow-up order includes

  • 8 LGB2 Boxer pumps and
  • 12 LDH5 series process pumps

These pumps are used for transferring monoethylene glycol (MEG) from the Tie In Platforms (TP) to the Well Head Platforms (WHP) and on-site MEG injection. This injection is intended to prevent the ice formation in the drill hole that can occur during the formation of methane hydrate. The project will be completed in 2019.

The plant will increase the gas output from 70 million m³ up to 126 million m3 per day.

Heat transfer oil circulation pump acc. to DIN EN 733

Saturday, December 9th, 2017 von admin

Fig.1 The new NKX heat transfer oil circulation pump

The pump manufacturer Dickow has developed a new pump line NKX for circulation of thermal oil. The pump casing is designed for 16 bar and 350 °C. The new pump line extends the application limit of the previous NKLs-type. The new NKX will replace the series NKLs with exactly the same dimensions in future.

The NKX is used as a circulation pump for hot oils in industrial heating plants/units. The performance range covers capacities up to 400 m3/h and differential heads up to 90 m in 50 Hz services; and capacities up to 2,500 US-gpm and differential heads up to 400 ft in 60 Hz services. The dimensions and performance range of these centrifugal pumps are according to DIN EN 733, that means range is subdivided into different pump sizes in order to achieve best efficiency for all service conditions inside the envelope.

Pump Engineer – Study Courses 2018 in German and English

Thursday, December 7th, 2017 von admin

Since 2005 the study programme for pump engineers provides specific training and know-how in terms of academic extra occupational, distance-learning study courses. During these 12 years approximately 30 lecturers have trained more than 300 pump experts coming from different branches – be it manufacturers, operators or planners.

According to Prof. Dr.-Ing Helmut Jaberg, who initiated the pump engineer study programme, the reasons for its success are the following: “The high level of appreciation with regard to our training offers can be measured by the fact that companies, whose employees have already graduated from the study courses, are increasingly encouraging their staff to take this training. Thus, the German study course which started in July 2017 reached the record number of 37 participants. We are really glad to see that companies repeatedly send employees to participate in our programme. Obviously the way it is performed – with a certain rigour and yet with a good sense of proportion – is well received by them.”

Novozymes and Grundfos kick off collaboration for clean water

Monday, December 4th, 2017 von admin

When you combine biotech with cutting-edge water technology, you might find new solutions to some of the most pressing global issues concerning water scarcity. Thereby, you can make a direct impact on the UN’s Sustainable Development Goal 6, aiming at securing universal access to water and sanitation by 2030.

This is the scope, when world’s leading experts in enzymes and microorganisms, Novozymes, and Grundfos, one of the leaders in advanced pump technologies, enter an open innovation collaboration.

An ‘alignment free’ pump

Wednesday, November 29th, 2017 von admin

It is imperative that pumping systems are designed and operated in a way that reduces the amount of harmful stress placed on components. One area that has been difficult to achieve and maintain is shaft alignment. Failure to properly align a pump’s mating shafts will eventually lead to challenges associated with shaft fatigue and failure, resulting in compromised pumping-system uptime, reliability and safety. This can then result in costly maintenance or even knock the pump out of service and halt production.

Focused on this problem, Blackmer developed GNX Series sliding vane pumps, which are called by the manufacturer “industry’s first alignment-free”. It is a reduced-speed pump for use in both portable and stationary applications.

Bubble-free filling of oil dampers

Monday, November 27th, 2017 von admin

Filling of oil dampers in low-volume and pilot production is mostly manual work. There is a lot of potential for improvement by a compact, flexible dosing system which includes a micro metering pump. This self-priming micro annular gear pump can work without an application of compressed air to the reservoir.

On the one hand, this saves the cost of compressed air including the necessary devices and, on the other hand, avoids the introduction of compressed air into the silicone or hydraulic oil. The medium can be filled bubble-free, gently and without loss of quality.

Tailor-made Slurry Pumping Solutions

Thursday, November 23rd, 2017 von admin

After the took over of almost complete solid matter pump programme for abrasive and abrasive/corrosive media from the insolvent company Arthur Habermann the Aurum Pumpen GmbH has set itself the objective of improving both the design and the materials engineering of its pump series. In initial orders for a major customer, newly designed pump solutions have already been developed, implemented and built.

Because the Aurum-Habermann heavy duty pumps are true solids handling pumps in terms of impeller geometry and design, these cannot conform to the lightweight construction of a standardised pump, and are thus individually adapted to requirements. In terms of materials, Aurum supplies the Habermann heat-treated steel qualities that have proven themselves over decades.

Oscillating displacement pumps for extraction with Carbon Dioxide

Sunday, November 19th, 2017 von admin

Carbon dioxide is used particularly in the food, beverage, cosmetics and pharmaceutical industry for extracting natural substances, aromas, fats, oils, waxes, polymers, enzymes and colourants in their supercritical physical state. For despite its bad reputation as a greenhouse gas, CO2 is a natural and environmentally-friendly solvent which has advantages over synthetic and harmful media such as n-hexane when it comes to sustainability.

Oscillating displacement pumps are ideal for supercritical CO2 extraction.

Metering pumps optimise cathode materials for lithium batteries

Saturday, November 18th, 2017 von admin

Solenoid diaphragm metering pumps type gamma/ X

Ternary oxide systems containing lithium guarantee a high energy density, long service life and high number of charge cycles for lithium storage batteries. Metering systems ensure the quality of the precursors needed for production.

The most important storage materials for lithium ion batteries are lithium nickel manganese cobalt oxides, or NCM for short. Various manufacturers in China have specialised in the production of the ternary precursors needed for this. Their appearance, particle size, size distribution, declared purity, beat density and many other characteristics are important to determining the properties of the sintered cathode end product. The manufacturers needed to find reliable and accurate metering pumps and systems that were able to meet the stringent quality requirements of manufacturing ternary precursors.

Energy-efficient pump systems for water supply

Friday, November 17th, 2017 von admin

With the use of the permanent magnet technology, oddesse pumps and motors factory developed an energy-efficient pumping system to support water supply companies to sustainably reduce energy consumption and thus contribute to the protection of the environment.

In the past, the efficiency of pump systems was often calculated by solely considering the efficiency of the pump. The efficiency of the motor, on the other hand, which is determined by the ratio between the electrical input and the mechanical output, has been largely ignored. However, the overall efficiency of the complete pumping system has an impact on the energy costs, which, as the decisive factor, account for more than 80% in the efficiency analysis. By optimizing the overall system, the greatest savings in electricity costs can be achieved.
