About Sandpiper

The brand's product catalogue comprises standard / containment-duty ball and heavy-duty flap valve pumps; air / natural gas-operated pumps and running sprayers. Sandpiper diaphragm pumps are designed for pumping applications involving abrasive slurries, suspended and non-suspended solids and line-size solids in wastewater management facilities and sewers. They are wet-tested after the final assembly to ensure the proper functioning of dead hanging, self-priming and sealing facilities. The brand's float switches are capable of opening / closing the air supply to the AODD pumps as the liquid level rises / falls inside a tank. These pneumatic switches can handle a maximum operating pressure and temperature of 125 PSI and 190 deg F, respectively.

This system includes patented cross-drilled pressure ports to eliminate spool drifting due to vibrations and / or unbalanced pressure or system conditions. Users can get easy access to the patented, cross-drilled pilot shuttle containing the two O-rings that most commonly fail on any AODD (air-operated double diaphragm) pump with continuous usage.

Frequently Asked Questions

What does AODD mean?

An air-operated double diaphragm (AODD) pump is a type of positive displacement pum designed to move slurries, solvents and high viscosity liquids. These fully sealed units can be partially or completely submerged in a liquid, providing minimum risk of contamination. In addition, they are driven by compressed air other than electricity which reduces exhaust and spark hazards.

What does deadhead mean in a pump?

Deadhead takes place when a diaphragm pump operates with no flow due to a closed or blocked discharge valve. The pump, in such conditions, recirculates the same water causing the water temperature to rise and shut off to prevent any damage to the internal components.

Do these submersible pumps need lubrication?

No, Sandpiper pumps can run dry without using oil or other lubricants. This means that they do not stall or get clogged due to a lack of lubrication.

Are Sandpiper pumps suitable for use with hazardous materials?

Yes, Sandpiper AODD (air-operated double diaphragm) pumps are designed for handling various chemicals and viscosities of even the harshest and most abrasive fluids, including thick sludges and slurries. They feature bolted construction that provides exceptional leak-free performance and includes TPE (thermoplastic elastomers) or PTFE diaphragms to move the pumped fluid.

Can Sandpiper pumps handle high-pressure applications?

Yes, Sandpiper pumps are available for handling high-pressure applications. These specialised pumps, such as AODD high-pressure pumps are used for moving thick, viscous fluids over a long distance. They incorporate two additional air chambers and one extra side driver diaphragm which doubles the surface area on which air pressure is exerted, magnifying the force by doubling the air inlet pressure. The resultant pressure is then delivered directly to the pumped fluid via diaphragms for easy pumping application.
