Abstract: A valve cover assembly and a liner retainer assembly configured to retain a plug, a liner, and/or a liner seal within or against a module or retention body of a fluid end of a pump. The valve cover assembly and the liner retainer assembly include pistons coupled to a retaining flange or a threaded gland. A bias applied to the pistons biases the retaining flange and a threaded gland that is coupled to the retaining flange, or the piston alone, into engagement with the module or retention body to retain the plug, the liner, and/or the liner seal on the module.
