Abstract:
A braking arrangement for drive heads or pump heads, to be preferably used in a progressing cavity pump (PCP) system in oilfields, consisting of at least one disk moving inside a viscous fluid and facing a static disk, in which mechanical energy is transformed into heat. The viscous brake is a device acting as a function of the rotation speed, in which a higher speed generates a higher braking power caused by the increase of friction among the disks and the fluid. The arrangement may comprise more than one mobile and static disk assemblies, as well as a hollow axis instead of a solid one, to allow housing the pumping rod inside the axis, and may also comprise an anti-reverse bearing.

Claim (Index 11):
The braking arrangement according to  claim 2 , wherein the brake is engaged to the polished bar of the pumping rod placed inside the hollow axis.
