The Seadraulics 420bar water jetter is an industry standard jetting system, with proven reliability with impressive pumping capabilities. No other system offers the same power density and reliability. This unit is capable of 420 bar at the nozzle. The turbo nozzle that comes as standard with this unit, has proven time and again to get the best overall cleaning. The auto rotation jetting spread that comes from this nozzle, means that movements by the ROV automatically clean a larger area more evenly. With 20 LPM being forced out the nozzle this water jetter will blow the debris away from the target cleaning area, and with the 420 bar a thorough clean results. This water jetter is a good choice for smaller ROV auxiliary pumps, and lighter cleaning jobs, compared to its bigger brother the HPW520. Its power levels mean that it does not damage subsea paint, unless it has already started to flake off and degrade, but hard marine growth will be a challenge for it. Most work class ROVs will run this water jetter on there auxiliary pumps easily.

Simple to interface, with the incorporated custom drive manifold, which means that the unit can be used on a wider range of ROV’s, as it allows the user to limit pressures and flows depending on the customers hydraulic supply abilities. Unit is supplied complete with hydraulic hoses, and Multi-D handle with turbo nozzle.
