Abstract: Disclosed is a device for loading and unloading modules relative to a pressure vessel and utilized in reverse osmosis systems. The device includes an elongated support for receiving the modules, a fluid actuated cylinder located at one end of the support and a clamp at the opposite end of the support for clamping the support to the open end of the pressure vessel. As each module is disposed on the support, the cylinder is actuated to extend its piston whereby the piston head displaces the module along the support into the open end of the pressure vessel. Additional modules are similarly loaded into the pressure vessel whereby the modules are serially arranged within the pressure vessel. To unload the modules from the pressure vessel, a rod is disposed between the piston head and the first module and the fluid actuated cylinder is actuated to displace all of the modules in the pressure vessel axially toward its opposite open end whereby the module first disposed into the pressure vessel is first unloaded therefrom. Additional rods are utilized to successively unload the modules from the opposite end of the pressure vessel, the near ends of the rods nesting one into the other, with each rod having a pair of centering plates to maintain it axially aligned in the pressure vessel and with the center pipe of the modules.
