Air Side

Sandpiper AODD Pumps

AODD pumps are air (or natural gas) operated displacement type pumps which uniquely differ from all other positive displacement pumps.  As a result of air pressure acting on the entire surface of the diaphragm, the diaphragm is in a balanced condition while pumping.  This measurably extends diaphragm life over that of mechanically operated diaphragm pumps.  Because compressed air is limited, the maximum pressure developed by the pump is also safely limited.  Thus AODD pumps are appropriately selected fort on-demand intermittent requirements.

Design Features

  • Variable flow and head conditions are achievable with the use of inexpensive off the shelf air line pressure regulators.
  • AODD pumps safely operate on deadheaded/standby demand without added costs associated with the need to relieve pressure.
  • AODD pumps are self-priming from a dry start, but these pumps are frequently installed in flooded suction installations as well as on suction lift installations (Max. dry prime of 24ft). They can also be submerged for maximum installation versatility
  • Pumps high viscosity fluids efficiently
  • Seal less, no mechanical seals or packing to leak
  • Runs dry without damage or heat build up
  • Fully groundable
  • Portable and submersible
  • ATEX, CSA, UL, CE, USDA, FDA and ABS certified

What separates Sandpiper pumps from the competition?

  • ESADS+Plus (Externally Serviceable Air Distribution System) is reliable, consistent, lube-free, and serviceable without the need to dismantle the pump.
  • Diaphragm connecting rod guaranteed not to yield under tension, compression or pump operation
  • All bolted construction improves sealing and withstands 4 times the pressure of v-band clamps
  • Bottom discharge porting is ideal for difficult solids handling

Special Duty Pumps

  • High Pressure Diaphragm Pumps – up to 250PSI discharge pressures, designed for filter press feed and applications requiring higher discharge pressures.
  • Non-Clog Wastewater Pumps – fitted with swing check valves and easy access clean outs
  • UL Listed Pumps – meets UL79 standards for pumping flammable liquids
  • Portapump Submersible Pump – Portable submersible pump that connects to 12V battery power. Weighs only 33lbs. and can fit through openings as small as 10”
  • SludgeMaster Submersible Air-powered trash pump – handles mud, leaves, twigs, sand, sludge, trash-laden water and soft solids to 1.5” Weighs only 59lbs, and can fit through openings as small as 14”
  • Natural Gas Operated Pumps – CSA certified for operation using sweet or sour natural gas to power the pumps.
  • Complete Filter Press Systems – multi-pump systems combine a high volume fill pump with a high pressure feed pump. Frequently used for filter press feed applications, the system produces operating pressures to 250PSI.  This results in shortened press cycles, drier cake and less costly disposal.
