In 1986, QED's AutoPump® originated the automatic air-powered pump concept, leading the industry ever since. AutoPumps were designed specifically to handle difficult conditions reliably and safely, including hydrocarbon (LNAPL and dissolved phase) remediation, solvent (dissolved phase and DNAPL) cleanup, suspended solids, silts, corrosives and high viscosities, along with high temperatures and frequent starts and stops. Air-powered AutoPumps, proven worldwide at thousands of remediation sites, are the No. 1 choice of professionals based on reliability, durability, performance range and technical support.
