Sandpiper’s GODD Pump, the G20, is a gas-operated double-diaphragm pump that has been designed to be powered by natural gas. The AODD application driven by natural gas created a set of unique safety requirements that did not exist prior to its creation. A partnership was created between Sandpiper and the Canadian Standards Association (CSA®) to lead the development of the first-ever safety certification for gas-operated double-diaphragm pump. The concern that comes with this applications is the static electricity build up caused by the material and product movement which if the static discharge is released, a sparking could happen which could lead to a flash fire and potential explosion. The CSA specification 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 diaphragms and check balls.
