Description

Seadraulics 460 bar water jetter is a compact and integrated all-in-one unit based on the reliable and highly regarded Dynaset HPW series pump.

The patented HPW-pump utilizes the reciprocal motion of a hydraulic piston. Hydraulic supply from the ROV moves the piston assembly until one of the water plungers reach the end position; the incorporated reversal valve then changes direction of hy-draulic flow so the piston assembly is set in the opposite direction. The motion causes a Vacuum to be developed at the pump intake line and a positive pressure is developed in the output line. Pumping fluid for the water jetter is taken directly from the surrounding seawater. However, if required, Seadraulics Pty Ltd can supply appropriate compensators and extra valve assem-blies to allow the system to pump most types of alternative fluids, such as Transaqua, Glycol and other well control fluids.

On/Off Control of the hydraulic supply to the Dynaset pump, is via a Sun hydraulics cartridges sized for the maximum flow rat-ing of the pump.
