Abstract: A clamping device for fixing a drive shaft of a delivery pump inside a rising pipe of a borehole for the delivery of a delivery fluid. The clamping device includes a housing with a first passage bore, through which the drive shaft of the delivery pump passes. The clamping device also includes at least a second lateral passage bore, which meets the first passage bore orthogonally, wherein a mechanically acting clamping means is accommodated and/or guided in the second passage bore, by means of which clamping means the drive shaft of the delivery pump can be fixed axially and/or radially in the housing of the clamping device. A method for the spatial fixing of a drive shaft of a delivery pump in a stationary manner in a rising pipe assigned to a borehole is also disclosed.

Abstract: A reverse rotation protection for borehole pumps is disposed in a drive head. The reverse rotation protection includes a housing and a clamping tool for securing a polished rod. The clamping tool includes at least two exchangeable contact elements with which the polished rod can be fixed releasably.
