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.

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.

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.

As a replacement to conventional submersible pumps, the manufacturer Hermetic supplied two 8-stage, sealless canned motor pumps. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals manufacturer, thus saves the costly, time-consuming conversion of the existing systems in its production plant.

Pumpex has been a part of Sulzer since 2011. Sulzer has formed a new business segment called Mining and Construction in 2016. This business segment will include all Sulzer dewatering activities worldwide. All product brand names currently used in this area will be terminated during 2016 in order to create one strong Sulzer brand for all dewatering products.  As a result, the Pumpex brand name will be phased out during 2016.

The new pump series is developed for the pumping and recirculation of activated sludge in wastewater treatment plants during the nitrification and denitrification process, as well as for the pumping of storm, surface, and river water. It complements the submersible recirculation pump series ABS RCP. These submersible pumps are optimized in low energy consumption to bring savings in total life-cycle costs and reduce the environmental footprint.

KBL’s (Kirloskar Brothers Limited) new “i-NS” pump is a non-clog sewage submersible pump designed for dewatering function in the

• water & wastewater treatment industries,
• sewage,
• building & construction and
• other allied segments.

The compact size of the pump helps in minimizing submergence, and it comes with an aesthetically-improved design for maintenance-free work.

The new Hidrax™ HT thrust bearings are developed for high-temperature applications in electric submersible pumps. These pad bearings can sustain unit loads of 8 MPa (1160 psi) at oil bath temperatures up to 300°C (572°F).

Technological advances in steam-assisted gravity drainage are increasing operating temperatures and placing increased demands on the thrust bearings located in the motor seal/protector section of the electric submersible pumps string.

South Africa is currently dealing with the problem of acid water because underneath the old gold mining city of Johannesburg is a lake which contains heavily contaminated water, which spreads horizontally and vertically into the abandoned pits of the former gold mines.  Meanwhile, the water line has reached a critically high level, as determined by the specialists from Andritz Ritz, which was given the first order to drain the mine water in 2010. The execution of the project was delayed by four years however, and it was only in spring 2014 that two powerful submersible motor pumps were installed in the middle of Johannesburg city centre, in the so-called “Central Basin”, with each pump capable of bringing 1,500 m³/h of water to the surface.
