The swivel transfers the high-pressure water from the hose to the drill string. Wassara Swivels are designed and dimensioned to be robust and withstand the high pressure during water-powered drilling.
Top mounted swivel
A top mounted swivel is placed above the rotation unit (when drilling downwards). This is the primary choice when the rotation unit can handle the high water pressure.
LKAB Wassara offers two top mounted swivels: WS150 and WS200.
An in-line swivel is mounted below the rotation unit and the alternative when a top mounted swivel is not preferred.
LKAB Wassara offers one in-line swivel: WS In-line.
