Sandpiper’s GODD Pump, Gas-Operated Double-Diaphragm Pump, the G30 

Sandpiper’s gas-operated double-diaphragm (GODD) pumps, the G30 has been designed to be powered by easily accessible natural gas. The application of the AODD Pump 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 of this application is the potential for static electricity build up due to material and product movement which the release of these static discharge 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 diaphragms and check balls.

Sandpiper’s Metallic GODD Pump, the G30, has a variety of highlighted features that showcased the GODD Pump’s advantages in its industrial applications. Amongst the highlighted features are;

• Safely powered by compressed air or natural gas depending on the application. Dual power capabilities offers simplified purchasing, maintenance and training while reducing inventory.
• Elastomeric seals are compatible with the various chemicals normally expected to be found in sweet and sour gas.
•  Every pump is leak-factory tested to 150 psi to ensure natural gas emission are properly contained.
• Complies with NACE Standard MR0175/ISO15156 for corrosion resistance.
• Constructed to prevent accumulation of static electric charge and fully ground-able to ensure static electricity dissipation (comes standard with attached grounding strap)
• Hydrostatic strength tested pressure to 500 psi (five times the maximum operating pressure, the highest standard in the industry)
  • Canadian Technical Letter R-14 requires 500 psi
  • ANSI LC6 requires 400 psi
  • Hydraulic Institute requires 188 psi
• Sandpiper’s ESADS+ allows complete access to the main air and pilot valves without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors)
