Cleanup well conditions can be downright hostile: powerful solvents, gasoline and fuel oil, strong acids, caustic bases, corrosive chlorides. That’s why QED makes the Pulse Pump series (our basic gas displacement pumps) in a variety of proven materials that won’t just survive, but will deliver years of trouble-free performance.
Every Pulse Pump model has only two moving parts downwell: high-clearance, self-cleaning ball check valves. This simplicity keeps them working when high solids, viscosity, or chemical attack cause other pumps to clog or breakdown. An external controller is required to control the alternating pressurization and venting cycles for the pump.
The Pulse Pump design is especially suited for sinking hydrocarbons (DNAPL) recovery, which is often complicated by high viscosity and/or extremely aggressive solvents.
Intrinsically safe Pulse Pump systems are fast and easy to install, with no electrical connections at the wellhead.
Flow optimization is simple too; rugged, dependable pumps and controllers (the solar/AC powered C100M and the all-pneumatic L360) deliver reliable operation without needing frequent attention or repair.
Even in the harshest environments, they just keep working - in the most demanding ground water cleanup, leachate collection, and sinking layer recovery applications.
