Water Swivels Heavy Duty For Rotary Drilling
Our Heavy Duty range of Water Swivels are used to carry the flushing medium from the pressure supply hose to the rotating Drill String. This flushing medium may be water, mud fluids or compressed air. The spindle of the water swivel is supported in the bearings of which depending on the type of swivel they are either plain or ball bearings and are grease lubricated. The drilling fluid is sealed in by a combination of “V” packing and “O” rings.
The Swivel spindles are subject to high loads and therefore are manufactured from high grade alloy steel and are heat treated or in some cases hard surfaced to improve strength and wear properties.
The following chart lists the important technical details of the Drillwell Water Swivel range and will assist with the selection. Further assistance maybe obtained by contacting our Technical department. If you require a bespoke design then we can supply them on request, please email or contact us for further information.
All our Water Swivel products are designed and manufactured in house by our fully qualified engineers allowing us to provide a custom service and a fast turn around.
