High pressure diesel water jet system for remote sites

It is a cleaning and jetting unit in which a diesel engine drives a high pressure plunger pump. Water is pressurised and delivered through hoses, lances or nozzles for industrial cleaning, descaling, surface preparation and hydro blasting. Because it carries its own engine, it works where electricity is not available.

Choose diesel when the site has no reliable power, when you move between locations, or for outdoor, offshore and remote work. Choose an electric unit where stable power is available, as it runs quieter, has no exhaust and usually costs less to run in a fixed location such as a plant workshop.

Riggers Pumps diesel units are configured from 500 to 2800 bar and 15 to 200 LPM. Higher pressure suits hard scale and coatings, while higher flow clears loose material faster. Tell us the job and tool you plan to use and we will recommend a working pressure and flow.

Engines range from 30 HP to 300 HP. The required power depends on pressure multiplied by flow, so a high-pressure, high-flow unit needs a larger engine. We size the engine with a margin so it runs at a comfortable load for long operating hours.

These systems use a high pressure triplex plunger pump, driven by the diesel engine through a suitable gearbox or belt drive. Triplex pumps give smooth flow and are designed for heavy-duty, long-duration work. The pump is sized so it runs within its rated pressure and speed for long service life.

Yes. Diesel water jet systems are used for concrete removal, hydro demolition and surface preparation on construction and repair work. These jobs normally need higher pressure and flow, so share the depth of removal and area to be covered. Trailer mounting makes it easier to move the unit along the work area.

It can be, when the unit is built with the safety features those areas require. Tell us the zone classification and site rules at the enquiry stage so the engine, enclosure and controls can be specified to suit. Offshore use may also need marine-grade frames and corrosion protection for long service.

Yes, it can cause serious injury if used incorrectly. Operators need training, proper protective equipment, rated hoses and fittings, and a dump or safety control. Never point the jet at a person, and depressurise the system before changing nozzles or fittings.

Keep pump seals, valves, a pump service kit, nozzles, hoses, filters, belts and fittings. For diesel units, also stock engine filters and consumables. Having these on hand avoids long stoppages on remote jobs. Tell us the job length and site location and we can suggest a spares list to carry with the unit.
