AODD pumps are air (or natural gas) operated displacement type pumps which uniquely differ from all other positive displacement pumps. As a result of air pressure acting on the entire surface of the diaphragm, the diaphragm is in a balanced condition while pumping. This measurably extends diaphragm life over that of mechanically operated diaphragm pumps. Because compressed air is limited, the maximum pressure developed by the pump is also safely limited. Thus, AODD pumps are appropriately selected for on-demand intermittent requirements.
Air-Powered Single Diaphragm High Pressure Metallic Pumps deliver discharge pressure twice the inlet pressure, up to 250 PSI (17.2 BAR). Designed for filter press feed and applications requiring higher discharge pressures. Available in Aluminum, Cast Iron and Stainless Steel with various elastomer options.
The Blagdon N25 and N50 High Pressure Pumps provide enhanced power in applications where pressure is paramount and flow rate is an issue. Using two air chambers to double the air per stroke, these pumps achieve discharge pressure up to 238 PSI (16 Bar) with flow rates as high as 30 gallons per minute for N25 and as high as 90 GPM (341 LPM) with N50.
The AirVantage Difference
AirVantage is a new technology for Air Operated Double Diaphragm pumps that significantly reduces air consumption over conventional AODD pumps.
Benefits of AirVantage
- Reduces Air Consumption: Field testing shows up to 50% savings over conventional AODD pumps. AirVantage Technology is available with Sandpiper® metallic pumps with discharge line sizes of 2" or greater. Sandpiper center section upgrade kits are also available.
- Adapts to Process Conditions: Using an advanced learning program that receives velocity feedback from an embedded sensor, AirVantage optimizes energy consumption and automatically adapts to changes in system demand, constantly managing energy consumption.
- Powered Only by Compressed Air: AirVantage uses a self-contained 12V power generator that converts a tiny portion of compressed air to power system electronics for managing energy.
- Saves Energy while Maintaining Flow: Field trials have proven that AirVantage can maintain comparable flow capacity while reducing air consumption saving thousands of dollars in annual energy costs.
- Increases Productivity: By using less air to operate pumps, AirVantage allows for more compressed air capacity system-wide to run more pumps generating greater productivity and better throughput.
- Reduces Compressor Maintenance: Air compressors with reduced demand need fewer repairs, saving customers thousands of dollars in maintenance and repair parts.

The SludgeMaster™ Submersible, Air-Powered Trash Pump handles mud, leaves, twigs, sand, sludge, trash-laden water and soft solids to 1 1/2" (3.8cm). High capacity, low head. The pump weighs only 59 pounds (26kg), and can fit through an opening as small as 14" (35cm). Sturdy construction for rough handling and long life. Optional rock screen available.
SANDPIPER Drillers Series pumps operate on compressed air and are designed for the toughest drilling applications. The durable roll cage and skid base configurations provide portability and pump protection. The flap check valve design allows passage of larger solids than traditional ball valve pumps and is ideal for your drilling 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 and is enhanced with an extended wear package.

HDF Pumps are recommended for abrasive slurries, suspended and non-suspended solids and line-size solids. All SANDPIPER® Heavy Duty Flap Pumps are configured with bottom discharge porting to prevent settling solids from shortening pump life and provide superior suction lift. Most HDF pumps are thick wall constructed of Sand Casted Aluminum, Cast Iron and Stainless Steel with elastomer and TPE (thermal plastic elastomer) diaphragms and check valves. See Individual pump descriptions for more detail.
Natural Gas Operated Pumps are CSA* (Canadian Standards Association) certified to ANSI LC6 standard for operation using sweet or sour natural gas. The pumps are also compliant with NACE Standard MR0175/ISO15156. The gas pump utilizes Aluminum or 316 Stainless Steel wetted construction with Nitrile or FKM or Virgin PTFE diaphragms and check valves. The gas valve is constructed of Aluminum with Nitrile or FKM (fluorocarbon) elastomers. Pumps are fully ground able, preventing static discharge.
