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.

- 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.
The Sulzer product portfolio for the water and wastewater business consists of
- submersible sewage pumps,
- submersible mixers and flow boosters,
- turbocompressors as well as
- pump control systems.
The six submersible motor pumps supplied last year by Andritz to Jurong Shipyard, Singapore, were started up successfully on two drilling platforms in the North Sea. The pumps convey the industrial water for cooling the drilling equipment from a depth of 20 meters. Installed in the supporting legs of the platforms, each of these four-pole submersible motor pumps conveys around 600 m³/h of industrial water.
New additions to the Weda electric submersible pumps range are 1 HP and under, c-UL-us approved, 60Hz single-phase drainage, sludge and residual pumps. They come in two voltage variants, 115V and 230V, and join the 50Hz range. Each of the Weda electric submersible pumps is now available in a 50Hz and a 60Hz version. The range consists of the Weda 04 and Weda 08 drainage pumps, the Weda 04B residual pump and the Weda 04S and 08S sludge/trash pumps.
