In 2012, Sulzer introduced the XJ series of submersible dewatering pumps with high hydraulic performance, increased wear resistance and high-efficiency motors. The new XJ 900 is a performance range extension of the XJ series pumps.
The new pump is equipped with a high-efficiency electric motor rated 90 kW for 50 Hz markets and 108 kW (145 hp) for 60 Hz markets. The high-efficiency IE3 motor and new hydraulics combined with low-friction bearings reduce power losses. As a result, the total energy costs are low.
The hydraulic design allows for easy conversion between high-head and high-flow configurations. This makes it possible to stock fewer pumps and still have the right hydraulic performance for the job.
