Fluid Engineering is proud to represent Warren Rupp and its line of natural gas powered air-operated double-diaphragm (AODD) pumps. Natural Gas Operated Pumps are CSA (Canadian Standards Association) certified for operation using sweet or sour natural gas. The pumps are also compliant with NACE Standard MR0175/ISO15156. The sweet gas pump utilizes Aluminum or 316 Stainless Steel wetted construction with Buna or Virgin PTFE diaphragms and check balls. The gas valve is constructed of Aluminum with Buna or FKM (fluorocarbon) elastomers. Pumps are fully groundable, preventing static discharge. A Stainless Steel gas valve option is available on G15 to G30 pumps for corrosive applications.
