In this short series of articles, Rafael Ocampo examines the basic theory concerning fatigue, the influence of stress raisers on fatigue failure, and the steps to take to reduce fatigue failures. 23 February 2010
When an Arizona power plant wanted to increase the capacity of pumps used to avoid the possibility of overflow, it was imperative the pumps be protected from the elements, making conventional solutions untenable. However, fluid handling consultancy, Quadna Inc, came up with the answer. 20 January 2010
A farmers’ cooperative in Germany has been drying animal feed since 1976. They decided to retrofit their equipment after a defective seal allowed hot oil to escape on New Years Eve 2008. Allweiler provided them with new pumps and a disturbance notification device to maintain safe and reliable energy production. 25 November 2009
Wet scrubber FGD plants play a critical role in reducing emissions of sulphur dioxide from coal-burning power stations. However, the abrasive and corrosive wet limestone slurry used in this process demands pumps of high levels of reliability. Wernert pumps provided the answer for one European power station. 06 November 2009
A coal-fired power plant in the Philippines was in such a state of disrepair that its reduced output was losing revenue. However, the onsite overhaul of four boiler circulation pumps in record time by the Hayward Tyler Group, minimised plant downtime for the customer, which is now operating at increased output levels 06 November 2009
Two-shift operation in power stations has brought its share of problems with systems that were originally designed to be operated continually. As Brian Germaine relates, the challenge was finding a hydraulic solution allowing the pump to operate efficiently over a wide operating envelope. 06 November 2009
Running pumps as turbines is a well-known concept in the water supply industry. It is seen as an efficient method of generating power as well as recovering energy and contributing to savings. The payback period can be as short as three years and there is the added benefit that pumps are less complicated to operate than turbines. Bryan Orchard reports. 06 November 2009
Since fossil fuels will be important for energy production for the foreseeable future, the emission of carbon dioxide CO2 cannot be avoided in the short term. Sulzer Pumps supports the drive to save energy and reduce emissions by providing state of the art high efficiency industrial pumping systems. 09 October 2009
Multiphase pump technology is a relatively new technology, and its development was marked by a number of test projects in which successful results paved the way to its effective use today. Bornemann, which supplied the pumps to be tested, looks at how initial installation problems were resolved so that the pumps could fulfill their potential. 22 September 2009
Wet scrubber FGD plants play a critical role in reducing emissions of sulphur dioxide from coal-burning power stations. However, the abrasive and corrosive wet limestone slurry used in this process demands pumps of high levels of reliability. Wernert pumps distributed by AxFlow in the UK provided the answer for one European power station. 01 September 2009
Wernert NE pumps reduce emissions of sulphur dioxide from coal-burning power stations. 23 July 2009
Summer 2009 sees a new challenge to the land speed record for a steam car, 'Inspriation'. Technology from CAT PUMPS is playing a critical part in this record-breaking attempt. 23 July 2009
There are many ways to increase the efficiency of pumps. Here, Lew Beck at Oconee Nuclear Station discusses two of them: firstly the use of ceramic type coatings applied to pump internals such as the impeller and casing, and secondly through the renewal of original fits and tolerances. 05 June 2009
Despite the tight credit markets and challenging global economy, 2008 saw further consolidation within the pump sector. Listed below are the transactions that took place during the first and second quarters of 2008. Third and fourth quarter deals were published in the February 2009 issue of Pump Industry Analyst. Subscribers to Pump Industry Analyst have access to a 4-year archive on the website as part of their annual subscription. 03 June 2009
The concept of sustainable buildings is beginning to gather pace, at least in part, and moves in the UK such as the new Building Regulations Part L2 have heightened energy consciousness. However, warns Kevin Jones of Schneider Electric Services and Projects, there remains the need for architects, building services engineers and those commissioning buildings to have a better understanding of the roles different equipment can play. 20 March 2009
As our energy reserves dwindle while costs continue to rise and as the spectre of climate change looms ever larger, it becomes ever more imperative to take action on energy savings. Recent legislation is now making the route of no-action impossible. Danfoss' John Martin, strategic business area manager, HVAC put the case forward for intelligent inverter speed control of fans and pumps in buildings. 20 March 2009
Corrosion is the greatest problem encountered in stainless steel structures widely used in seawater pumps - even specialised brine pumps such as those used in desalination, oil & gas, chemical, thermal and nuclear power plants. Here, M Miyasaka and H Yakuwa of Ebara discuss the solutions currently on offer for surmounting crevice corrosion and take a look at the latest advances in this field. 20 March 2009
For decades it has been common practice to use circulation pumps in household central heating systems. The advantages are simple: a low noise level, an efficient wet runner motor and a maintenance-free design. Dr. Holger Krasmann, General Manager of the WILO Pump Group in Germany, explains the development of the technology and predicts its dramatic effects on energy consumption. 20 March 2009
Large buildings are prone to enormous variations in their water use. Any new system would need to match these variations using the least amount of energy. Here's how the world's largest commercial building met this challenge with a system that will not only pay for itself on energy-savings, but will also pay the costs to replace itself in its lifetime. 02 March 2009
When a Croatian hotel needed a wastewater treatment plant installed on site, but had no existing connection to the municipal sewer tunnel system, a bespoke plant was the only realistic option. A system of modular PE sewage treatment tanks with six Tsurumi submersible aerators was a cost effective solution that also met local noise level requirements. 02 March 2009
One of the more challenging applications for a pump is the hazardous conditions on an oil rig out at sea. A European oil and gas equipment manufacturer ensured that pump operators were safe by using a range of Bosch Rexroth products to remotely control its diesel engine-driven pumps. 02 March 2009
Multiphase boosting is widely accepted by major oil companies. When a large-scale oil project in Algeria prioritized high reliability and safety of the whole pump system and required a single point responsibility, it looked to German manufacturer Bornemann Pumps to provide a solution. Specialists in twin-screw technology and multiphase boosting, the company was on hand to demonstrate its strength as a pump supplier and as a partner for turnkey solutions. 02 March 2009
