Abrasive Water-jet Cutting System


The Abrasive Water-jet Cutting System (AWCS) is a high-integrity, flexible cutting system. Developed for use in Explosive Ordnance Disposal (EOD) or other hazardous applications, the AWCS enables EOD operators to remotely carry out decommissioning and low order techniques on unexploded munitions in a safe and remote environment. The AWCS high-pressure system provides the capability to cut virtually any material and is used by EOD Operators to assist in rendering safe unexploded munitions including air dropped bombs and large artillery projectiles of various sizes. All modules are manually portable and where necessary equipped with large diameter wheels, lifting handles and lifting points or eyelets.

About This Product


THE MANIPULATOR & FRAME: The manipulator assembly consists of three independently driven axes. Normally it is mounted on the manipulator frame, but as this unit is self-contained, it can be mounted on any stable platform using the end brackets. The manipulator is waterproof to three metres, has a low magnetic signature and has quick release clutches for easy setup. The frame provides a stable mounting base for the manipulator. There are standard set-ups for common tasks, but the frame can also be configured in non-standard forms to meet the requirements of more complex tasks that may be encountered. The frame is manufactured from standard size scaffold tubing and has a low magnetic signature. The feet have holes for securing the frame on uneven ground, and a high friction rubber sole provides additional grip on hard surfaces.

HAND CONTROLLER: The Hand Controller is used to program manipulator functions for cutting and wash out operations. This unit communicates via the 17m Cable Reel and provides feedback to the system operators by way of progress reporting, built in test (BIT) routines and a series of fault codes. The hand controller has an emergency stop switch and BIT functions. This unit has a simple and intuitive design for use with gloved hands and has backlit controls for use in low light conditions.

ENGINE/PUMP MODULE: The Engine/Pump module consists of a single cylinder diesel engine with charging coil, a high pressure pump and AWCS power control box. The engine drives the high pressure pump and provides electrical power to the system. There is a pressure control valve and guage as well as a safety relief valve to ensure full control of the pump. The water reservoir can be continually topped up fom a local water cource, or the Water Supply Module (WSM). The Engine Pump Module is supplied with removable wheels, suitable lifting handles and lifting eyes.

  • 12v electric key start
  • Dims 900 x 580 x 710mm (L x W x H)
  • Weight 135Kgs
  • 690 Bar
  • 6 litre per minute
  • 50 litre water header tank
  • Pressure gauge
  • Pressure control valve
  • Safety relief valve (700 Bar)


SLURRY MODULE: The Slurry Module provides the means of reliably mixing a controlled rate of abrasive slurry to the high pressure water flow from the pump module. The main part of the Slurry Module is the high pressure vessel which is filled up with the suitable abrasive in accordance with the process parameters and the operating instructions. Cutting time of the Slurry Module is limited by the adjusted discharge quantity. For longer running cutting processes the Slurry Module must be refilled as required.

  • 12 litre mixing/storage vessel
  • Outlet & recharge control valves
  • Pressure gauge
  • Safety relief valve (715 Bar)
  • Rupture disc assembly
