| One of the most common misconceptions of the average person is in thinking that dredges are strictly used for gold mining. While this is what they were originally developed for, the usefulness of the dredge today is as varied as are makes and models. From oyster harvesting and marina cleaning, to complex diamond plants or simple golf course water hazard cleaning, dredges are expanding their horizons by the day.
Keene Engineering manufactures some of the most unique, powerful and versatile dredges on earth today. Dredges and dredging systems that are capable of handling nearly any type of application. If you can think of it, we can build it. |
|
| Take our Nessie Dredges for example, our crown jewel of dredges. Nessie is a state of the art machine and the first real portable cutterhead dredge on the market.
Our Nessie Dredges offer more then 6 implement options, aside from its standard revolutionary cutterhead, which make it the most versatile dredge in its class. Operations such as Hyacinth and Tule clearing are a snap for this machine and marina cleaning has never been easier! Give us a call for more details and information! |

Portable and cost effective venturi operated dredge systems can transport slurries of rock, sand and gravel up to 150 feet away and no higher then 3 feet above water level. These systems range in suction intake size from 2 to 8 inches in diameter. Venturi systems can eliminate the need for costly gravel pumps. These particular systems are ideal for a variety of operations such as:

The above diagram shows a common system layout. This system draws clean water through the pump and injects a high pressure flow of water into the power jet. This flow creates a powerful vacuum commonly referred to as the “Venturi” system. While the Venturi system provides limited distance of discharge and out-of-water lift, it is the most cost effective system for transporting material relatively short distances.
