Air Operated Centrifugal

Sandpiper SludgeMaster Series trash pumps are ideal for handling mud, twigs, sludge, sand, leaves and trash-laden water, as well as soft solids (1-1/2 inches) in water filtration and pond / fountain aerating systems. These units feature a self-draining design to prevent clogging, especially in freezing conditions and are also capable of self-priming for reducing manual efforts, thereby speeding up the draining operation. The robust 416 stainless-steel shaft and Buna N seal of the Sandpiper air pumps help handle abrasives / solid-laden fluids and prevent leakages, respectively.

Air Operated Diaphragm Pumps

Standard-duty Sandpiper air-diaphragm pumps are ideal for dewatering and pumping slurries, solvents, abrasive fluids, weak-acids and suspended solids in petrochemical and food processing plants. These pumps are designed to operate on a continuous supply of compressed air and feature aluminium / cast iron / stainless-steel / non-metallic construction to ensure structural rigidity. The brand's self-priming double-diaphragm pumps feature ball check valves for withstanding high-flow fluid flows and connecting rods for reliable & consistent diaphragm control. Choose from a wide range of these all-bolted shear-sensitive air diaphragm pumps, offered in Buna, PTFE and Santoprene(R) diaphragm materials on Raptor Supplies, an authorised Sandpiper distributor.

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.

Things To Consider

Cross-Reference Alternatives

Sandpiper MPNs cross individual references to the equivalent Aro and Dayton models for pumps and float switches. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Sandpiper products available.

Sandpiper Competitive Advantages

Externally Serviceable Air Distribution System

All Sandpiper pumps feature this exclusive ESADS+ technology that allows for quick and easy replacement of air valve and pilot valve components without removing the pump from the line. This technology offers quick remote site serviceability in under five minutes by simply removing only 4 bolts as compared to the standard maintenance process that takes up to an hour to dismantle the piece completely. 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.
