Abstract
A retainer assembly and plug for a fluid end of a pump system includes a retainer body. A plurality of tongues are movably arranged about the retainer body. The tongues are moveable between a pre-installed configuration and an installed configuration depending on the position of the retainer body relative to the tongues. In the installed configuration engaging flanges of the tongues are positioned in a retaining channel formed in a bore of the fluid end and retain the retainer assembly to the fluid end. A plug is configured to sealingly fit to the bore of the fluid end inboard of the retainer assembly and a locking mechanism is configured to secure the retainer assembly to the plug, and when so secured, the position of the retainer body is maintained relative to the plurality of tongues and the retainer assembly is maintained in the installed configuration.
