Abstract
An apparatus for rotating a tubing string of a pumping wellhead is described which includes a housing having a first end, a second end, and an interior. The first end has a stationary external coupling communicating with the interior. The second end is adapted for attachment to a wellhead. A drive assembly is disposed in the interior. The drive assembly includes a rotatable tubular member having a first end and a second end. The first end of the tubular member is disposed within the interior of the housing in fluid communication with the stationary external coupling. The second end of the tubular member extends past the second end of the housing thereby providing a rotatable coupling engagable with a tubing string. The drive assembly rotates the tubular member. Bearings are disposed between the tubular member and the interior of the housing thereby facilitating rotation of the tubular member. Dynamic seals are disposed between the tubular member and the interior of the housing.
