Abstract

The invention relates to a sealing system for sealing a drive head of a borehole pump relative to a borehole. The drive head consists of a drive and a casing. The sealing system is disposed on a base of the casing, wherein a polished rod extends through the sealing system. The sealing system is releasably connected to the base of the casing.
