Water Well Drilling Rig KS400 by KOONSA

The KS400 has a rated drilling depth of up to 400 meters, depending on ground conditions and tooling selection.

The rig can drill hole diameters from 105 mm to 325 mm to accommodate a wide range of water well and construction requirements.

The KS400 is powered by a Weichai National Three engine delivering 103 kW, with an operating speed range of approximately 1600–1800 rpm.

The KS400 supports hydraulic rotary and propulsion drilling as well as down-hole impactor (hammer) drilling. It is equipped to use medium- and high-pressure impactors.

Maximum rotary torque is rated at 8000/4000 Nm (two-stage), with maximum rotary speeds of 75 and 150 rpm (two-speed range).

Rapid rise speed is 28 m/min, fast feeding speed is 55 m/min, and the rig offers a push-through capability of 7 meters for advancing casing or rods.

The KS400's air pressure range is 1.2–3.5 MPa with an air consumption range of about 16–55 m³/min, depending on drilling method and depth.

Standard compatible drill pipe lengths are 6 meters with pipe diameters typically between 89 mm and 114 mm.

The rig is designed for mobility with a walking speed of about 2.5 km/h and a climbing angle capability of up to 20°. Shipping dimensions are approximately 6550 mm × 1900 mm × 2750 mm.

The machine's operating weight is listed around 6,800 kg, with an overall/shipping weight of approximately 10 tonnes (depending on optional equipment).

Optional equipment includes mud pumps, centrifugal pump generators, foam pumps and different hammer/impactor models to suit specific drilling conditions.

The KS400 is intended for use in loose layers and bedrock and is commonly used in water well, mining and construction drilling projects. Actual performance depends on geology and tooling.

Typical penetration efficiency ranges from about 10 to 35 meters per hour, but this varies widely with formation type, tooling, and operational parameters.

Yes. Each unit comes with a machinery test report and an outgoing inspection video to document factory testing and quality checks.

The KS400 includes outriggers with a support reach of 1.5 m, a winch lifting force of 1.5 tonnes, shaft pressure rated at 4 tonnes and a rig lifting force around 22 tonnes. Standard safety and stabilizing components are provided for secure operation.
