Some dredge basics - Keene Engineering, Inc.
In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140-foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.

Venturi PrincipleHow do venturis work
Classically, his theorem is used in the design of aircraft wings to create lift from the flow of air over the wing profile. There are basically two applications for a venturi. By attaching manometers to three sections of the tube, the pressure drop can be measured and the flow rate through the throat calculated. This is termed a Venturi Meter.

Proline Gold Mining and Prospecting Equipment/Gold Dredges
2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner-tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.
