Abstract

1. A submerged propeller pump of the type comprising a motor having a shaft which is guided in two bearings and onto which is keyed a propeller, the said motor being housed in a body including a first chamber (28) filled with oil and provided with a first flange (25) connected to a corresponding second flange (23) on a pump body (15), the said pump body (15) exhibiting a casing (20) extending from the first flange up to the propeller coaxially with the shaft (3) and a perforated wall connected to a ring (17) circumscribing the propeller and integral with a third flange (16) in order to connected to a delivery pipe, characterized in that one of the bearings (5) to the motor (1) is offset longitudinally in order to be arranged in the pump body and is supported by a support (35) integral with the first flange (25), the first chamber (28) of the body (2) being in communication with a second chamber (70) arranged in the support (35) and opening onto the bearing (5), a turbine being keyed onto the shaft in the second chamber (70) and a return circuit (46, 47, 48, 50) towards the first chamber (28) being provided so as to create a continuous lubrication circulation through the bearing and an overpressure.
