Sandpiper GODD Pump, the G20, is a gas-operated double-diaphragm pump that has been designed to be powered by easily accessible natural gas. The application of AODD Pumps driven by natural gas created a unique set of safety requirements that did not exist prior to its creation. Sandpiper partnered with the Canadian Standards Association (CSA®) to lead the development of the first-ever safety certification for gas-operated double-diaphragm. The inherent danger in this application is the potential for static electricity build up due to material and product movement which the release of these static discharge in these applications could lead to a sparking which in turn could lead to a flash fire and possible explosion. The CSA specifications sets standards to prevent static electricity accumulations as well as standards for burst pressure; heat resistance, leakage and upper and lower temperature operation. The pumps are fully ground-able and are constructed of materials compatible with sweet and sour natural gas; Aluminum or 316 Stainless Steel wetted construction with Nitrile or Virgin PTFE diaphragm and check balls.
