Abstract

In the assembly the motor, e.g. a hydraulic motor 6, is provided downstream of the pump 11, 19 and is arranged to drive a shaft 9 to which pump impellers 16 are fixed. This arrangement permits the shaft 9 to work under a torsion and traction combined load. A pipe 3 surrounds the pump 11, 19, and an upstream seal 22 is provided so that the liquid pressure at the discharge of pump is transmitted to the space between the pipe 3 and the pump housing to enable the latter operate under compression. The pipe 3 is fitted with a filter 2 and is located in the drill hole 1 with a body of gravel 4 therebetween.
