Green pumps for a green stadium

Tuesday, January 16th, 2018 von admin

Croke Park is a major Gaelic Athletic Association (GAA) sports venue located in Dublin that hosts events for a number of sports. Croke Park has been at the heart of Irish sporting life for over a hundred years, it is not only an iconic landmark but also the third largest stadium in Europe.

Since 1884 the site has been used primarily by the GAA to host Gaelic games, most notably the annual All-Ireland finals in Gaelic Football and Hurling. In honour of Archbishop Thomas Croke, one of the first GAA’s first patrons, the stadium was renamed to Croke Park.

Pumping and Mixing with a Minimum of Energy Consumption

Monday, January 15th, 2018 von admin

Packo Pumps in Belgium and Daniatech in Denmark have bundled their expertise in pump manufacturing and mixing and have set a new standard in high-shear pumps.

The patented rotor-stator design was optimized with CFD and gives the pump an unrivalled energetic efficiency. “The energy consumption is 40 % to 50 % lower compared to other high-shear pumps”, so an information of the manufacturer. “This high efficiency does not only result in a lower energy bill for every hour the pump is in operation, but also reduces the initial investment. The high-shear pump can be fitted with a smaller motor and the possible frequency convertor is also smaller and cheaper. The optimized flow through the rotor-stator also results in a very quiet operation.”

Sulzer doubles capacity of high voltage testing to improve repair times

Thursday, January 11th, 2018 von admin

Performance testing of high voltage motors and generators is usually carried out to determine benchmark data following a major repair. However, increasingly, customers are requiring this information as part of a problem diagnosis or to verify performance figures for a component when its essential data has been lost. To keep up with growing demand, Sulzer has made a major investment at its Falkirk Service Center (Scotland) that will enable the test-bed load capacity to be doubled.

Until now, the Falkirk site has used a 1,250 kVA diesel generator that operates through two step-up transformers to provide 3.3 – 11 kV via high voltage switchgear to the test cell. This setup ensures a reliable power source for testing that is not affected by local demand on the power grid. The new investment will add a 2,000 kVA and a 700 kVA generator to the site that will be synchronized through a 4000A LV switchboard, as well as a new 2,500 kVA transformer, that will double the capacity of the test bed.

This new AODD pump is transferring blackwater onboard the hospital ship Africa Mercy, the largest civilian hospital ship in the world. Founded in 1978, Mercy Ships is a global charitable organization that operates a fleet of hospital ships specially designed for use in developing nations.

Many people in Africa have little or no access to healthcare. For nearly 40 years, Mercy Ships has delivered free services valued at more than $1 billion – directly impacting more than 2.5 million children and families. As a state-of-the-art hospital ship, the Africa Mercy brings volunteer medical teams and sterile operating rooms directly to people who would otherwise go without care.

Predicting Performance Curves of Centrifugal Pumps In the Absence of OEM Data

Wednesday, January 3rd, 2018 von admin

Technical paper by: Jayanthi Vijay Sarathy

M.E, CEng, MIChemE, Chartered Chemical Engineer, IChemE, UK

Chemical and Mechanical Engineers in the oil & gas industry often carry out the task of conducting technical studies to evaluate piping and pipeline systems during events such as pump trips and block valve failures that can lead to

  • pipes cracking at the welded joints,
  • pump impellers rotating in the reverse direction and
  • damaged pipe supports due to excessive vibrations

to name a few. Although much literature is available to mitigate such disturbances, a key set of data to conduct transient studies are pump performance curves. A pump performance curve is a plot between pump head and flow rate. In Greenfield projects, when no pump vendor data is available, a necessity arises to use performance curves to conduct pipeline/piping studies to check for parameters such as design pressure.

KSB: High-efficiency motor with integrated frequency inverter

Wednesday, December 20th, 2017 von admin

Prototype demonstrates potentia: The KSB Group has finished the prototype of a super-compact high-efficiency motor with an integrated frequency inverter. The 22-kW synchronous reluctance motor is a prototype featuring new semiconductor technology that provides completely new cooling management for eliminating heat from power electronics.

By integrating the frequency inverter into the motor, developers were able to reduce the unit volume by over 25 percent compared with the traditional design.

New inline single stage centrifugal pump range

Monday, December 18th, 2017 von admin

The new SIL pump range was developed by Sulzer to meet the process requirements in various general and industrial applications. The SIL pump range is developed for pumping mainly clean and slightly contaminated liquids, viscous liquids up to 250 cSt, and fibrous slurries up to a consistency of 1%. The hydraulic design ensures efficient pumping with a low NPSHr (net positive suction head required) across the whole pump range.

The inline design together with the monoblock construction makes the SIL pump compact, rigid and reliable. The pump is available either with an integrated motor or with a standard IEC motor. SIL pumps are easy and fast to install both in vertical and in horizontal positions, and they require only a small installation space.
