High pressure water jet ring system can be used in presence of compact, very dry or clay materials.
For electric pumps it can be used as an alternative to hydraulic cutters.
This system consists of a jet ring frame, mounted on the pump filter, a high pressure centrifugal pump (available in electric and hydraulic versions), a scution hose with water filter and non-returns valve and a delivery line.
