SandPIPER 1″ N25 High Pressure Air Operated Double Diaphragm (AODD) Pump

In pump category: SandPiper High Pressure

The SANDPIPER N25 1″ (25 mm) Metallic High-Pressure Pumps provide double the power in applications where pressure is paramount and flow rate is an issue. These high-pressure air pumps are ideal for thick, high-viscous fluids (high specific gravity), high head pressure applications and moving fluids a long distance.

Using two air chambers to double the air per stroke, these AODD pumps achieve high discharge pressures and excellent flow rates. Other features and benefits include:

2:1 high pressure with full flow of a traditional 1″ or 2″ pump with the capability to overcome a higher pressure range. For example, a traditional 1″ pump ends at 125 psi; the N25 can achieve pressures of 125-232 psi (8.6-16 bar).

Simple construction and ease of maintenance

Self-priming end-ported for improved flow

N25: pressures to 232 psi (16 bar), flow rates up to 30 gpm (136 lpm)

N50: pressures up to 232 psi (16 bar), flow rates up to 92 gpm (350 lpm)

Bolted construction for greater integrity and reliability

Optional weighted valve balls for high specific gravity and viscous fluids applications

Reliable pneumatic air valve

Safely deadheads: stalls against closed head without damage

Restart on demand
