Moving water distribution networks towards the future

Friday, November 30th, 2018 von admin

Baseform and Grundfos collaborate to bring new, digital and smart water solutions to utility customers to optimize distribution networks, drive high energy efficiency, minimize water losses and ensure sustainability in asset management planning.

Fast-paced, specialized knowledge and a global presence are accelerated when Baseform and Grundfos join their competencies in big data and in water solutions on a new collaboration through intelligent, data-driven water technology. It offers urban water utilities a unique opportunity to use big data to spot where to improve network efficiency – and ways to realize the improvements.

Submersible borehole pumps for very high heads

Tuesday, November 20th, 2018 von admin

These new submersible borehole pumps developed by KSB have a diameter of up to 50 inches, i.e. 1250 mm, and a drive rating of up to 5 MW. These pumps will be capable of handling

  • flow rates of up to 5000 m³/h
  • at heads of up to 1500 m.

Compared with dry-installed pump sets, the advantage of submersible borehole pumps is -acc. to an information of the manufacturer- “the notably longer service life and the fact that pumps with wet motors are not compromised by flooding.” KSB is one of the few manufacturers worldwide to offer double-entry designs for particularly high load conditions alongside “normal” single-entry designs.

This double-entry design was originally used for drainage applications in mines. The heads required in these applications would have created very high axial thrusts in single-entry pump designs, placing extremely high loads on the bearings. The back-to-back impeller arrangement employed in double-entry designs not only reduces the axial thrust but also the associated bearing loads.

Multiphase pumps for oil-water-sand-gas mixtures

Wednesday, September 19th, 2018 von admin

The global hunger for oil and gas continues unabated, which means that exploration companies are striving to achieve higher and higher yields and are also increasingly developing difficult sources, such as heavy oils with an extremely high solid content. Methane from coal seams or highly viscous oil at more than 10,000 mPas are already of commercial interest today but are just as complicated to extract as oil-sand mixtures from the Sudanese desert. Conveying systems in particular have to be adapted to the media and the environment if production is to be efficient under such conditions. Netzsch Pumps & Systems has developed a multiphase pump precisely for this area of application. It can handle mixtures of oil, water and gas along with sand content, achieving flow rates of up to 600 m³/h.

Pumps cut power consumption at Palazzo Grassi in Venice

Thursday, August 16th, 2018 von admin

One of the most important museums of contemporary art in Italy, the famous Palazzo Grassi in Venice, is able to considerably improve its energy balance due to the use of pumps with highly efficient, intelligent drives. The pumps and valves to modernise the heating and air-conditioning systems were supplied by pump manufacturer KSB.

For a building of historical and architectural significance, maintaining a particular room temperature and humidity as well as air quality is a costly and major challenge. After a careful analysis of the energy consumption, those responsible for building management started an extensive refurbishment project in 2015. Planning and installing a completely new pumping infrastructure in a historic building presents a great challenge since the building was not designed for such equipment.

Providing the best water in Karelia

Tuesday, July 10th, 2018 von admin

The Northwest of Russia literally flows with water. An area known for huge lakes and vast wetlands. Petrozavodsk is the capital, and the largest city, of the republic and most of the 300,000 inhabitants get their drinking water from the nearby Lake Onega. But some new settlements on the outskirts of the city have chosen another source. “We get our water supply from an aquafer, that covers most of southern Karelia. Three large pumps from Grundfos deliver water to our building complex with around 5,000 people,” explains Vitaliy Markov, General Manager of Drevlyanka Vlll – a part of Chistiy Gorod.

Systematic flow metering – instrumentation for water supply in desert region

Tuesday, January 30th, 2018 von admin

Aguas de Saltillo, the water utility company which serves the city of Saltillo in Mexico, is responsible for supplying drinking water to a population of around 850,000. To ensure a reliable supply in this arid desert city, the company relies on a water network which draws from several reservoirs with the aid of process instrumentation from Siemens. The Sitrans F M MAG 8000 electromagnetic flow meters used here are outstandingly robust, durable and reliable, as well as requiring minimal maintenance. Over a hundred of these devices have now been installed in the Aguas de Saltillo network.

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.

Indar deliver largest submersible motor pump sets ever

Monday, October 16th, 2017 von admin

Facing the worst drought on record in the Colorado River Basin, as lake levels continue to fall, the Southern Nevada Water Authority (SNWA) is building a low lake level pumping station to ensure Las Vegas and Southern Nevada maintains access to its primary water supplies in Lake Mead. Lake Mead water levels have dropped more than 40 m (131 feet) since the drought began in 2000. The new pumping station will allow SNWA to pump water from Lake Mead from an elevation as low as 267 m (875 feet) above sea level into the water treatment facilities and further on to provide water to the city of Las Vegas and neighbor community area.

Sustainable business builds a better world

Monday, January 16th, 2017 von admin

The Business and Social Development Commission takes a thorough look at a challenged world in a report released today. It is called ‘Better Business, Better World‘, and it focuses on how joint action from the political, societal and business spheres is decisive, if the world is to reach the UN’s ambitious Sustainable Development Goals by 2030. Among the key messages are that it is necessary to build sustainable business models around the global issues, if they are to be resolved in a sound and long-lasting way, and that the time for action is now.

“This report is a call to action to business leaders. We are on the edge and business as usual will drive more political opposition and land us with an economy that simply doesn’t work for enough people. We have to switch tracks to a business model that works for a new kind of inclusive growth. Better Business, Better World shows there is a compelling incentive for why the latter isn’t just good for the environment and society; it makes good business sense,” says Mark Malloch-Brown, Chair of the Business and Sustainable Development Commission and former Deputy Secretary-General of the UN.
