<p>A pump is provided with a stationary impeller housing having a motor driven diagonal impeller mounted therein. A diffuser is mounted coaxially with the impeller for converting the kinetic energy of the pumped fluid into a pressure head. A hollow body mounted in the diffuser defines a diffuser passage in which curved diffuser blades are mounted. The impeller has a conical hub having a diameter equal to 40-80 percent of the maximum diameter of the impeller blades.</p> |
