A rotating control device can include an annular seal, and a latch including a rotary cam and an engagement member which releasably secures the seal and/or a bearing relative to the housing, such that rotation of the cam relative to the housing displaces the member. A method of latching an annular seal relative to an outer housing of a rotating control device can include rotating a rotary cam, thereby linearly displacing an engagement member that releasably secures the seal relative to the housing while permitting rotation of the seal relative to the housing. Another rotating control device can include an outer housing, an annular seal, and a latch including a rotary cam and multiple separate engagement members disposed in the housing, and in which rotation of the cam relative to the housing displaces the members in the housing.

Rotating control device with rotary latch

A seal bore protector for protecting a seal bore of a rotating control device (RCD) is provided. The seal bore protector includes a cylindrical body, a throughbore extending through the cylindrical body, and a sealing element disposed around an external surface of the cylindrical body. The sealing element includes a first sealing ring, a second sealing ring, and a sealed area between the first sealing ring and the second sealing ring. The sealed area is fluidly coupled with a port when the seal bore protector is installed in the rotating control device.

Frictional support of seal bore protector

A pulling tool is used for setting or removing an internal component of a rotating control device (RCD). The pulling tool includes keys that extend outward for engaging with an inner surface of the internal component. The keys are spring loaded so that as the pulling tool is pressed through the internal component, the keys collapse inward until the keys are moved into a mating internal groove profile on the inner surface of the component. The pulling tool is able to selectively engage with and release from the component, both when the component is disposed in the RCD and when outside the RCD. This facilitates a mechanized installation and/or removal of the internal component from the RCD without relying on a friction force and without applying a torque or providing hydraulic fluid to the pulling tool.
