Flood protection is an important subject and has become a focal point for large cities looking to prepare for heavy rain events. On Monday December 3rd,  Smith Pump Company conducted a tour of three City of Dallas Concrete Volute Pump Stations for the South Florida Water Management District (SFMWD).  

SFMWD has a new project and are considering the concrete volute pump technology.
The above depiction gives you an idea of the size of these concrete volute pumps. As the name indicates, large pumps can be made of concrete for the stationary components like the formed suction intake, the suction bell, and the volute. 

First Three In The U.S.A.

The City of Dallas now has three operable concrete volute pump stations (CVP).  They are the only three CVP stations in the United States.  The technology has been around for many years but was originally developed in Europe.  Flowserve has a large number of CVP stations in the world, but got their start in the Netherlands.
 
Concrete volute pumps are used for high flow applications.  The three pump stations at Dallas are rated for 125,000 gpm per pump to 220,000 gpm per pump depending on which station.  They are made for low to medium head applications.  One of the CVP pump station's features is long runs between major repairs.
It was a busy day for Shane Keil and Granger Smith of Smith Pump Company to show these three pump stations called Pavaho PS, Baker PS, and Able PS.  The group photo was taken at the Pavaho Pump Station which was the first to be built.
 
The tour went well, and the group actually had the opportunity to see pump 9 at the Able PS operate for a short period of time.
Here you can see an aerial photo of a pump test at the Able Pump Station.
