N25 1" (25 mm) & N50 2" (50 mm) Metallic AODD High-Pressure – Ball Valve Pumps

    SANDPIPER BLAGDON AODD HIGH-PRESSURE PUMP

    The SANDPIPER N25 1" (25 mm) and N50 2" (50 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).
    • Material options suitable for a wide range of applications
    • 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
