<p>The pump (10) has a pump shaft (52), and a casing (46) delimiting a liquid circulation channel (44) with outlet orifice (12). The orifice is directed, so that the liquid escapes from the orifice according to liquid outlet axis (14) inclined relative to a longitudinal axis (22) of the shaft. A support system (64) of the shaft is placed in the channel, and comprises a support structure (66) secured to the casing and a bearing to guide the shaft. A pipe for passage of the shaft is extended from a casing opening (87) into the channel until the system. The shaft is extended freely through the pipe. An independent claim is also included for an aquatic activity zone for implementing a water stream by using a hydraulic pump.</p> |
