Water Swivels For Rotary Drilling
Our range of Water Swivels are devices 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. Before selecting a suitable Water Swivel for a particular operation it is important to give consideration to the following factors before making a final decision.
- Load carrying capacity
- Rotational speed
- Suitability for use water / mud fluids or air
- Physical size ( dimensions )
- Ability to handle pump volume
With the above in mind, Drillwell have designed and developed three ranges of water swivels complaint with the above requirements. The standard range ( low cost ) and the more rugged heavy duty range, we also manufacture a Lightweight Water Swivel. Each type of water swivel is supplied complete with a Rod Adaptor threaded with an appropriate Rod Thread.
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.
