Sandpiper HP20 High Pressure Metallic AODD Pump
Sandpiper 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 with high specific gravity, high head pressure applications and moving fluids over long distances. The pump incorporates two additional air chambers and one extra side driver diaphragm, doubling 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 the fluid diaphragms, allowing the Sandpiper HP20 to achieve high discharge pressures and excellent flow rates.
Some of the features highlight the advantages of the HP20 AODD Pump in industrial applications;
- Nearly 2:1 high pressure with the full flow of a traditional 2″ pump and 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), with 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.
-
Suitable for a wide range of applications:
- Available in Aluminum or Stainless Steel wetted path material.
