Sandpiper Metallic AOD High Pressure Pump, the SH2-M


Sandpiper Metallic AOD Pump, the SH2-M, is a 2:1 ratio high pressure pump and a single acting diaphragm pump driven by compressed air. Being the only high-pressure, air-operated diaphragm flap valve pump in the world, the unit can deliver discharge pressures twice the inlet pressure up to 250 psig (17.2 barg). The pump is mainly utilised in filter press feeds and other demanding applications requiring higher discharge pressures and/or solids-handling that most air-operated single-diaphragm (AOD) pumps are incapable of achieving. The pump has been engineered with metallic seats and heavy-duty flap valves to help ensure a durable valve seal for high-pressure performance. The SH2-M features a balanced diaphragm design which allows a minimal pressure differential across the diaphragm, helping to decrease the need for replacement parts, reduce downtime and lower the total cost of ownership. The SH2-M high pressure pump is available in both Aluminum and Cast Iron with various diaphragm elastomer options.

Sandpiper’s SH2-M High Pressure Pump comes with a variety of features that highlight its advantages in industrial applications;

  • Solids-handling:
    Handling solids up to 1.8″ (45 mm) in diameter, it is the only high-pressure flap valve pump in the world.
  • Heavy duty:
    Bolted construction and made with robust materials.
  • Suction stroke control:
    Independently regulated suction stroke allows for optimum stroke control.
  • ESADS+ Air Distribution System:
    Sandpiper is the only AODD/AOD Pump manufacturer to offer an externally serviceable air distribution system, allowing for quick and easy access to the pilot and spool valves without removing the pump from service. Repair or clean in 5 minutes (versus 55 minutes for competitors), reducing your downtime by as much as 90%.
