Abstract
A dual channel volute of a concrete volute pump (CVP) is prefabricated and then transported and assembled to its base at the application site. A cutwater recess is provided in the base into which the lower edge of the cutwater extends, thereby providing sufficient mechanical support of the cutwater to withstand all applied pressures and stresses during normal operation without distortion or failure. The base can further include a sidewall recess into which the lower edge of the sidewall extends. In embodiments, the disclosed volute is prefabricated in sections that are separately transported, and then assembled and sealed together at the application site. The cutwater and/or sidewall cuts that divide the sections can be within ten degrees of perpendicular to the cutwater and/or sidewall. An impeller chamber of the volute can be sufficiently large to contain an impeller having a diameter of at least 1.2 meters.
