Many jobs are carried out using a hand held jetting gun. In these circumstances the reaction force created by the water jet should not exceed 250 Newton’s (25kgf) to ensure the operator can work in a safe manner e.g. 35lpm at 1400bar.
Higher flowrate increases reaction force so the cutting nozzle needs to be constrained. At 120lpm at 1000bar it is common to use a gimbal device to connect the jetting gun to. For maximum productivity the HPS5000 pump with a performance of 200lpm at 1000bar is coupled to a hydrodemolition robot.
