17 Type Gun Nozzle Options For optimal results, the right gun nozzle is a critical factor to get the most optimal results. Results depend on the unique combination of job requirements, tool, operation pressure, flow rate, amount of nozzles, orifice diameter and jet angle. Doornbos has a dedicated range of gun nozzles for every water jetting job: 350 UP TO 1000 BAR (A) Flat jet nozzle Nozzle that provides a flat, inverted ‘V’ shaped, water jet and is ideal for cleaning/washing either delicate or larger surfaces. Wider impact surface, but the impact power is lower. (B) Orbital nozzle Combines the high power of a point jet with the large surface achievement of a flat jet. Forms a ‘ring’ shaped pattern and is also ideal for cleaning/washing delicate or larger surfaces. Wider impact surface, but lower impact power. 2500 - 3200 BAR (C) Rotating point jet nozzle holder Combine the high power of a point jet with the large surface achievement of a flat jet. Rotates by the reaction energy of the high-pressure water; no external driver is needed. Various configurations available. • Self rotating and fixed options • Fixed speed or variable speed • Operable with 2 up to 4 insert nozzles • A configuration available for every application (D) Fixed cavitation nozzle holder Cavitation non-rotating nozzle holders are suitable for demolition work at 3200 bar. They deliberately induce cavitation in front of the nozzle to produce extremely high, very localized stresses on a surface due to bubble cavity collapse in the jet stagnation region. Selecting the right gun nozzle for the job is a delicate process. Consult our experts for the best advice and results. A C B D HIGH PRESSURE WATER JETTING TOOLS SURFACE PREPARATION
