QED Environmental Systems' new Eliminator bladder pump

QED Environmental Systems’s new Eliminator high capacity bladder pump is designed to handle light nonaqueous phase liquids (LNAPLs) and dense nonaqueous phase liquids (DNAPLs), as well as viscous contaminants, including crude oil.

Available for 2-inch (50 mm) or 4-inch (100 mm) wells or larger, the Eliminator pump offers 100% air-powered operation, no contact between drive air and contaminated fluids, and simple flow optimization.

The Eliminator pump uses a bladder made of PTFE or elastomer to isolate the pump air supply from pumped liquid, so there is no contact between the air and the contaminated fluids inside the bladder. As a result there are no emissions of potentially contaminated air.

Featuring reliable top-inlet skimming or bottom-inlet pumping, the Eliminator is powered by compressed air that requires an external timer-based controller to control the air cycling on and off switch to the bladder pump.

A wide range of accessories is available, including roving well caps that allow accurate pump inlet positioning, and bladder replacement kits for easy field maintenance.
