PRCD 500 Series

Rotating Control Device (RCD)

The PRCD 500 series is based on the time-tested, patented design that has been the cornerstone of Pruitt’s success in the drilling industry.


The 500 Series RCDs are compatible with any flange or surface conductor pipe. Advances in R & D have led to the availability of the PRCD 508-G that requires no external lubrication, eliminating the need for maintenance by rig crew. The 500 Series RCDs come with a remote hydraulic clamp, but manual clamps remain available.
