Abstract
PURPOSE: To enable a well pump to be free from efficiency drop during low-head operation and usable as an exclusive-purpose high-head pump, by assembling a deep-well conduit block which comprises a second by-path conduit for steadily connecting a high-pressure part with a first by-path conduit and a discharge conduit communicated with the outlet of a venturi.
