Sulzer Acquires Ensival Moret

Combining the complementary product portfolios enables Sulzer to become a full line supplier in most industrial process applications.

Sulzer Expands its Range of High-Efficiency SMD Water Pumps

The SMD pump range is ideal for a wide range of high-volume flow applications where raw, clean, brackish or sea water is pumped. Such applications are water abstraction, treatment, transport, desalination, supply, and distribution. The pumps can also be used for firefighting, drainage, or distribution of heating and cooling media in residential and industrial systems.

Sulzer’s Currency-Adjusted Sales and Operational EBITA Remained Stable

Operational EBITA and operational ROSA continued to be stable in the first half of 2016. Order intake, impacted by oil and gas market headwinds, decreased, but increased by 8% sequentially in the second quarter of 2016. Significant savings from the Sulzer Full Potential (SFP) programme offset the impact from market headwinds.

Sulzer Launches New Highly Efficient Recirculation Pump

The new pump series is designed to recirculate and pump activated sludge in wastewater treatment plants during the nitrification and denitrification process, as well as for the pumping of surface, storm and river water. It complements the submersible recirculation pump series ABS RCP.
