Development of New Vertical Line Shaft Pumps

International technology Group ANDRITZ is a global leading supplier of plants, equipment, and services for hydropower  stations. The Pumps Division of the ANDRITZ GROUP develops and manufactures customized large pumps and standard centrifugal pumps for a wide range of different applications and industries.

The challenge

TURBOdesign1 was introduced at ANDRITZ for hydraulic development of a new vertical line shaft pump (Fig. 1). Due to changing requirements, the pump operating range had to be shifted to higher flow rates and higher heads. Thus, there was a need to develop new runner blades and new guide vanes. The hydraulic designs were verified by CFD, including all flow-relevant components.

 

 

The TURBOdesign Result

Compared with the old reference pump, the new design is characterized by a smaller size and by significantly higher blade loading, hence providing greater head and flow rate (s. Fig. 2).  Furthermore, the efficiency at the design point (OP1) could be improved.
