Abstract (en)
[origin: US2009148316A1] The invention relates to a pump device for feeding a delivery medium out of a deep borehole which leads from a floor level into the interior of the earth, which deep borehole is provided at least in sections with borehole piping, having a pump and having a motor which drives the pump. As a result of the motor being arranged outside the borehole piping and as a result of it being possible for the motor to be connected to the pump by means of torque transmitting means which extend laterally through the borehole piping, the motor can be protected from overheating, and in the event of a fault, can be pulled out of the deep borehole independently of the pump.
