Pressure Waterjet Cleaning Machine
Industrial High Pressure Waterjet Cleaning Machines
Wamit supplies industrial-grade high pressure waterjet cleaning
machines built for the most demanding cleaning and surface
preparation tasks. Our range covers 500 to 1500 bar operating
pressure, with electric and diesel-powered configurations
available. From pipeline hydro jetting and tank cleaning to
rust removal, paint stripping, and concrete demolition — each
machine is factory-tested before dispatch and backed by full
after-sales support, spare parts supply, and worldwide shipping.
Machine Specifications at a Glance
pressure range to suit every industrial application. Low to
medium pressure units (500–800 bar) handle general-purpose
cleaning, grease removal, and pipeline jetting. High pressure
systems (800–1200 bar) are suited to rust removal, paint
stripping, and surface preparation prior to coating.
Ultra-high pressure machines (1200–1500 bar) are used for
concrete scabbling, hydrodemolition, and SSPC/NACE WJ-grade
surface preparation. Contact our team to specify the right
pressure and flow configuration for your application.
What Is a High Pressure Waterjet Cleaning Machine?
A high pressure waterjet cleaning machine uses a precision
pump to pressurize water to between 500 and 1500 bar, then
forces it through a hardened nozzle to produce a focused,
high-velocity jet. That jet removes rust, mill scale, heavy
coatings, grease, chemical deposits, and concrete build-up
from metal, concrete, and composite surfaces — without
abrasive media, without chemicals, and without damaging the
base material beneath. The process is used across oil and gas,
marine, construction, food processing, and petrochemical
industries wherever thorough surface cleaning or preparation
is required before inspection, coating, or recommissioning.
How a Waterjet Cleaning Machine Works
Step 1 — Water intake and filtration
Water is drawn from a supply source and passed through an
inlet filter to remove particles that could damage the pump
seals or nozzle orifice. Clean, filtered water is essential
for consistent pressure and long component life.
Step 2 — High pressure pump
The filtered water enters a high pressure pump — either an
intensifier pump or a direct drive pump — which raises the
pressure to the operating level, between 500 and 1500 bar
depending on the application. The pump is the core component
of the system and is precision-engineered for continuous
industrial use.
Step 3 — Pressure delivery and control
assemblies fitted with rated couplings and safety valves.
The operator controls flow rate and pressure at the gun or
lance, with automatic pressure relief valves protecting
the system if pressure exceeds the rated limit.
Step 4 — Nozzle and jet formation
orifice, accelerating to high velocity as it passes through
the restriction. The nozzle type — fan, pencil jet, rotating,
or flexi-lance — is selected to match the surface geometry
and cleaning requirement.
Step 5 — Surface impact and cleaning action
kinetic energy directly to the contamination layer — rust,
scale, paint, grease, or biological growth — breaking the
bond between the contaminant and the substrate. Because no
abrasive or chemical is involved, the base material is left
clean and undamaged, ready for inspection, coating, or
return to service.
Key Features of Wamit High Pressure Waterjet Cleaning Machines
Every machine in our range is built for continuous industrial
use and tested to full operating pressure before leaving
the factory.
High-Pressure Output — Up to 1500 bar
Generates sufficient force to strip heavy mill scale,
thick protective coatings, rust, and chemical deposits
from steel and concrete surfaces in a single pass.
Effective in the most demanding industrial environments
including offshore platforms, refineries, and shipyards.
Industrial-Grade High Pressure Pump
Fitted with a precision-engineered intensifier or direct
drive pump designed for continuous duty cycles. Maintains
stable operating pressure across the full working shift
without pressure drop or fluctuation — critical for
consistent surface preparation results and repeatable
cleaning quality.
Heavy-Duty Corrosion-Resistant Construction
Frames and pressure-bearing components are manufactured
from corrosion-resistant steel and high-grade alloys
selected for long service life in wet, chemical, and
saline environments. Pump heads, valve blocks, and
manifolds are precision-machined to tight tolerances
for leak-free operation under sustained high pressure.
Portable and Site-Ready Configuration
Compact frame design allows the unit to be manoeuvred
through standard doorways, into confined spaces, and
across uneven ground without compromising structural
integrity or pressure performance. Trolley-mounted and
skid-mounted configurations available. Diesel-powered
models require no mains connection — fully self-contained
for remote site and offshore deployment.
Fully Adjustable Pressure and Flow Settings
Operating pressure and water flow rate are independently
adjustable to suit the surface material, coating type,
and cleaning specification. Fine pressure control
prevents surface damage on sensitive substrates while
full-pressure mode delivers maximum cleaning power for
heavy industrial stripping. Compatible with fan nozzles,
pencil jets, rotating heads, and flexi-lance attachments
for every surface geometry.
Operator-Friendly Controls and Quick-Release Fittings
Clearly labelled control panels with intuitive pressure
and flow adjustment. High pressure hose connections use
quick-release couplings for fast attachment changes
without tools. Service access panels are positioned for
ground-level maintenance — no need to dismantle the
frame to reach pump seals, valves, or filters. Reduces
operator training time and daily setup time significantly.
Integrated Safety Systems
Every unit is equipped with automatic pressure relief
valves that activate if system pressure exceeds the rated
operating limit. High pressure hose assemblies are rated
and tested beyond working pressure with burst-protection
sleeves at connection points. Trigger gun dead-man
controls shut off flow immediately on release. All safety
systems comply with CE machinery directive requirements
and are tested before dispatch.
Wide Cleaning Coverage and Precision Capability
Rotating nozzle heads and wide-angle fan jets cover
large surface areas rapidly — suited to tank interiors,
ship hulls, and concrete floor slabs. Pencil jet and
flexi-lance configurations access confined spaces,
tube bores, and complex geometries where rotating
equipment cannot reach. A single machine handles both
bulk cleaning and precision detail work by switching
nozzle attachments.
Modular Accessory System
A full range of accessories extends machine capability
without additional capital investment. Extension lances
reach into deep vessels and elevated structures.
Rotating pipe-cleaning nozzles clear blockages and
deposits from pipeline bores up to DN200. Abrasive
injection modules add garnet or steel grit to the water
stream for surface profiles that exceed the capability
of pure water alone. Spare parts are held in stock and
available for worldwide dispatch.
