HERE COMES THE STORY
OF THE SHURRICANE Ebara has rethought the hydraulic design used in multistage pumps. Utilising the latest in computational fluid dynamics and design, followed by rigorous testing, Ebara has developed a unique impeller design that offers solutions and value to the customer – the Shurricane.
T
he imbalance of forces acting on the front and rear shrouds of a conventional impeller results in axial thrust. This thrust load is compounding in multistage pumps, and has to be allowed for in the pump design. For pumps with conventional impellers, the existing solutions include having a thrust bearing built in the pump, or to use a special motor fitted with a larger thrust bearing. Both are costly and can be complicated. Another solution has been to simply have a smaller diameter back shroud to reduce the thrust. Ebara has rethought the hydraulic design used in multistage pumps. Utilising the latest in computational fluid dynamics and design, followed by rigorous testing, Ebara has developed a unique impeller design that offers solutions and value to the customer. The optimised shape of the Shurricane maintains high efficiencies and very significantly reduces the axial thrust – meaning that any standard IEC motor can be used and bearing life is improved.

Suitable for a range of applications
The range of Ebara vertical multistage pumps are suitable for a wide range of applications, in the industrial, commercial and agricultural fields. They can be used at water treatment plants (for reverse osmosis and filtration), for the pumping of hot or cold water for HVAC systems, for the pumping or boosting of water in general, and in boiler feed, irrigation and fire fighting systems. The pumps can be coupled with any motor, anywhere. Optional materials are part of the unique hydraulic design, and there are optional connections for customers to consider.
Built like a Katana
A Katana is a traditional Japanese product manufactured with care and precision. Only years of experience can give the necessary capacity to build a masterpiece. This is what Ebara does with its pumps. As a result of over 100 years of Japanese experience in pump design and manufacturing, their pumps offer high-quality performance, reliability, and cutting-edge technology. Ebara’s vertical multistage pumps are manufactured in Italy to the highest standards of quality, and achieve reliable operating performance by means of
