Sandpiper’s Metallic AODD Pump, High Pressure Pump, the HP20 

Sandpiper’s Metallic AODD Pump, the HP20 is a 2:1 high pressure pump that provides nearly double the force in applications where pressure and excellent flow rates are a priority. This high pressure air pump is ideal for thick, viscous fluids (high specific gravity), high head pressure applications, and moving fluids a long distance. The pump incorporates two additional air chambers and one extra side driver diaphragm. double the surface area on which air pressure is exerted. This magnifies the force by nearly doubling air inlet pressure. The magnified pressure is delivered directly to the pumped fluid via fluid diaphragms. The Sandpiper AODD pumps achieve high discharge pressures and excellent flow rates.

Some of the features highlights the advantages of the AODD Pump in its industrial applications;

• Nearly 2:1 high pressure with the full flow of a traditional 2″ pump with the capability to overcome a higher pressure range.
• Simple construction and ease of maintenance.
• Self priming and end-ported for improved flow.
• Pressures up to 232 psi (16 bar), flow rates up to 92 gpm (348 lpm)
• Bolted construction for greater integrity and reliability.
• Reliable pneumatic air valve is fully serviceable.
• Safely deadheads – stalls against closed head without damage.
• Restart on demand.
