Traditional air-operated double-diaphragm (AODD) pumps are designed to be powered by compressed air only. As an alternate power source to air, oil and gas operators have opted to power their diaphragm pumps with easily accessible natural gas, eliminating the need for an air compressor. 

The oil and gas industry application of AODD pumps driven by natural gas created a unique set of safety requirements that previously did not exist. In 2003, SANDPIPER recognized the need and partnered with the Canadian Standards Association (CSA®) to lead the development of the first-ever safety certification for gas-operated double-diaphragm (GODD) pumps.

CSA-certified GODD pumps are designed and tested to be powered by natural gas when installed, according to the certification and local requirements in the below-noted applications:

The HDF2 and HDF3 heavy-duty flap valve pumps are compressed air-driven and ideal in the upstream market for cellar sump and mud transfer applications. The flap check valve design allows passage of larger solids than traditional ball valve pumps (ideal for abrasive slurries, suspended /non-suspended solids, and line-size solids in oil and gas pumping applications).

The exclusive bottom discharge porting arrangement provides superior suction lift and eliminates the damage from settling solids in your pump. This heavy-duty pump features thick wall construction for extended wear.

Features & Benefits

  • Flap Check Valves: Ideal for abrasive and viscous fluids, sludge and slurry
  • Solids Handling: Up to 2" (50mm)
  • Bottom Discharge: Gravity assist is ideal for pumping liquids with settling solids and slurry
  • Portable: Safely and easily transported
  • Superior Dry Prime: Dry suction lift up to 24' (7m) of water
  • Bottom Discharge Porting: Eliminate the damage from settling solids in your pump with the exclusive bottom discharge capabilities of our heavy-duty ball valve and heavy-duty flap valve pump lines.
