Flow Rates from 300 to 3000+ GPM
Fox has supplied numerous liquid eductors for moving large water flow rates. Because eductors over 6” line size are custom-fabricated, specific flanged end connections can be specified, and special features can be included to meet specific requirements.
Two Recent Examples
The US Army Corp of Engineers specified liquid/liquid eductors to suck up 1500 GPM from 17 ft below the eductor, using available water pressure at 80 psig. Fox supplied four custom 10” liquid eductors designed to fit in a very tight space.
Another application required a completed submerged liquid eductor, suspended approx. 15 ft below the water level with cables, with a separate water line delivering motive water at 170 psig. This eductor used a straight through design, discharging approx. 800 GPM straight up thru an 8” pipe to surface. The suction port was supplied with a screen to prevent clogging from large debris.
Sand & Mud Eductors – for Wells, Lakes, Hydroelectric plants, & Seabed
Fox has supplied sand and mud eductors that can be dropped down through a small pipe from the surface to fluidize and pump out contaminated industrial or toxic waste from wells, lakes, tanks and seabeds. Through pipes as small as 4 inches, both the motive water line (down) and Fox venturi eductor discharge pipe (up) can slide down to the target sand, mud or sludge. Water jets on the eductor bottom discharge down into the muck to fluidize solids so they can be more effectively sucked into the submerged venturi, and the resulting slurry discharged up to the surface for proper disposal.
An installation of an 8 inch Fox eductor, submerged at the Playas Hydroelectric plant in Antioquia Colombia has been working perfectly and Fox is now being asked to engineer eight similar eductors at a much larger hydroelectric facility in Latin America.
