Abstract:
An air-operated pump, such as an air-operated diaphragm pump, includes a pump body, a process liquid pathway defined at least in part by the pump body, and an air pathway defined at least in part by the pump body, where the process liquid pathway and air pathway are fluidly separated from one another within the pump body. The pump further includes a leak detection and containment assembly integrated with the pump body and having a process liquid sensor configured to sense process liquid leaked from the process liquid pathway into the air pathway, and a shutoff valve communicatively coupled to the process liquid sensor and configured to close in response to the process liquid sensor sensing a process liquid leak to contain the leaked process liquid within the pump body and the assembly.
