The Rebco ROTXR Pump-Through Bottom Sub-Assembly is designed for use with Lock Mandrels and Equalizing Valves (valve type) and is selected based on the nominal size and profile of the Landing Nipple in use. The sub incorporates a spring-loaded Ball and Seat assembly that holds pressure only from below, while providing a means to pump fluid through the plug from above. The assembly consists of four components: a Cage, a Ball and Seat Sub-Assembly, a Spring Retainer, and a Spring.

Part numbers and full engineering data for the ROTXR are referenced in Section XVI (Plug Chokes), as this sub-assembly is integral to the plug choke system. When ordering, the operator must specify the Lock Mandrel size and type to be used, as well as the material required to suit downhole conditions and service requirements.

How to Order: Product Code 21. Specify Lock Mandrel size and type to be used with, Landing Nipple profile, and material to suit downhole conditions. Refer to Section XVI for part numbers and engineering data.
