It's easy to multiply the mixing force of pumped water. This nozzle requires as little as 7.5 gpm to draw in five times more. Molded of glass-filled polypropylene with smooth surfaces. We recommend a flow rate of 13-30 gpm between 10 and 50 psi for the ED1, 7.5-17 gpm at 10-50 psi for the ED2, 33-75 gpm at 10-50 psi for the ED3.
