| dc.description.abstract | A summary of the current technique of concrete volute pumps, a technique which is widely used in several countries (Germany, Great Britain, Italy, Netherlands, Portugal, South Africa, the Soviet Union and, more particularly, in France) is presented. The hydraulic performance obtained and the wide range of possible applications are mentioned. The main components of this type of pump and materials employed are described and the fundamental simplicity of this technology is highlighted. The advantages of concrete volute pumps are examined, including high reliability, maximum availability, low maintenance costs, excellent corrosion resistance, very little micro or macrofouling and vibration free behavior. The strong points of concrete volute pumps versus conventional vertical we pit pumps are presented in a comparative table. A quick look at the many possible areas of application gives the assurance that the use of such pumps will continue to grow. | en |
