| 摘要 |
The invention relates to an apparatus (1) for conveying liquids, in particular well water, comprising a motor, a crank (2) which is driven in rotation indirectly or directly by the motor, a pump pipe (3) in which the liquid can be conveyed, a lifting linkage (4) which is guided at least partially in the pump pipe (3) and can be made to perform an oscillating vertical movement indirectly by the crank (2), and also a reciprocating piston pump (5) which is driven by the lifting linkage (4). In order to be able to interrupt an operative connection between the motor and the lifting linkage (4) without making any modifications when changing over to an alternative manner of driving, the invention provides a flexible drawing means (6) by means of which the crank (2) can make the lifting linkage (4) perform a vertical movement. |
