The FlowMaster 350


Cities and municipalities worldwide realize the importance of quick accessibility to water valves and hydrants in the event of water contamination or water line breaks. Accessibility is necessary to quickly shut off water valves and stop the flow of water to main supply lines.

Many water valve boxes are filled with compacted dirt and spoil, which can take up to several hours to clean by hand. In emergency situations, time is of the essence, thus many cities have been prompted to clean their valve boxes using vacuum and exercise their water valves at least once a year to make them readily accessibile. Similarly, the need has arisen to flush water hydrants to determine if they are working properly, as well as flush out the system on an annual basis.
The FlowMaster 350 Series of vacuum excavation systems can be used to hydraulically exercise water valves and hydrants, making sure they will work properly in times of need. Compact in size, the FlowMaster unit can be easily transported to locations close in proximity to water valves and hydrants.

Two engine options are available in the FM350 Series units including a 36 and 49 hp diesel options. The FlowMaster can be fork/skid steer mounted or trailer mounted for transport.
