S20 Metallic 2" (50 mm) AODD – Ball Valve Pump


    The SANDPIPER 2" S20 Evolution Metallic AODD Pump is the highest-performing and most efficient AODD pump on the market. Equipped to handle abrasive fluids and suspended solids, this versatile and mobile pump has best-in-class flow rates and the lowest air consumption available.

    Material of construction options include: aluminum, cast iron and stainless steel with elastomer TPE (thermoplastic elastomers) and PTFE options in diaphragms and check valves.

    S20 Benefits

    • Max flow rate: The S20 is the world leader in maximum flow rate, allowing you to get your work done faster with up to 32% higher capacity.
    • Air consumption: The S20 requires up to 59% less air to operate, reducing the load on your compressed air system and lowering operating costs.
    • Air economy: SANDPIPER’s metallic standard duty pumps provide up to 2.5 times more gallons out for every cubic foot of air supplied.
    • Annual savings: SANDPIPER’S S20 Metallic Standard Duty Pumps can save you up to $3,170 in annual operating costs.

    S20 Features

    • Serviceability: The air distribution system (ADS) is one of the most frequently serviced parts of any AODD pump. Only SANDPIPER's ESADS+ feature allows access to the complete ADS without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors).
    • Simplicity: SANDPIPER’S original ADS is fully interchangeable, repairable and inline-serviceable. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory and increased cost of ownership.
