Discover our leading range of high-precision industrial recovery pigging units, ultra-high pressure water jetters, and smart municipal restoration machinery designed for heavy-duty operational efficiency.
In modern industrial, petrochemical, and manufacturing operations, maintenance is no longer just about longevity; it is a critical driver of structural safety, environmental compliance, and process efficiency. Over the past three decades, the global market has transitioned rapidly from aggressive chemical cleaners and simple mechanical abrasion tools toward highly automated, eco-friendly, and precise surface restoration tools and pipeline management equipment.
Foshan Dulles Equipment Co., Ltd. has stood at the absolute forefront of this technological shift. With over 30 years of experienced mechanical R&D, Dulles has evolved from one of China's earliest domestic pressure washer developers to a global exporter. The modern industrial landscape demands solutions that minimize downtime, reduce human error, and achieve total cleanliness metrics. Be it removing heavy marine fouling from ship hulls, descaling complex heat exchangers in sugar mills, or ensuring zero cross-contamination in lithium-ion battery slurry pipelines, our technical methodologies address these critical industrial bottlenecks.
By blending ultra-high-pressure hydraulic mechanics with smart diagnostics, Dulles offers standard-setting engineering for operators across Europe, the Americas, and the Asia-Pacific region. Our focus is to deliver complete environmental control alongside high efficiency, ensuring compliance with strict regional regulations regarding industrial emissions, water usage, and occupational safety.
Decades of empirical data, rigorous testing, and continuous process optimization translate into solid, verifiable performance indicators across our main product portfolios.
Our product lines are structured into four key technological paradigms, addressing challenges in surface preparation, pipeline maintenance, product recovery, and fluid management.
Utilizing high-strength triplex ceramic plunger pumps coupled with diesel or electric motors to generate up to 100 MPa of pressure. These tools remove rust, scales, polymers, and marine growth without thermal deformation or chemical contamination of the base metal.
Configured with DN65 to DN125 double-launch stations. Our pigging systems utilize precision-molded elastomeric cleaning pigs to achieve up to 99.5% product recovery in pipelines conveying high-viscosity media like lithium battery slurry, paint, and chemicals.
Equipped with 150m waterproof PTZ crawler robots. Our diagnostics line permits visual verification of internal tube structures, blockages, and corrosion patterns before and after the surface restoration process, ensuring total quality control.
Sourcing industrial machinery globally requires a deep reliance on parts availability, production speed, and quality control. At Foshan Dulles Equipment Co., Ltd., we combine the logistical advantages of China's primary industrial manufacturing hub with a high degree of vertical integration. Our self-built testing laboratories and automated assembly lines allow us to maintain control over the manufacturing tolerance of every high-pressure pump, frame, and dynamic manifold.
Key supply chain advantages we pass on to our partners include:
Our product portfolio is deployed worldwide in challenging industrial environments where safety, reliability, and speed are critical parameters.
Salt crusting, marine growth, and oxidation rapidly degrade steel hulls. Our 15000psi ultra-high-pressure water jetting machines provide chemical-free coating removal and surface preparation, leaving a clean profile for paint re-application.
Lithium slurry contains aggressive solvents and active materials that can deposit on pipe walls. Our Hyperfore Pigging Recovery systems recover high-value product, minimize waste, and enable rapid recipe switches with minimal solvent consumption.
Blocked lines, calcification, and tree root ingress are inspected via waterproof PTZ crawler cameras and cleared with high-pressure sewer jetters, restoring flow capacity without requiring expensive trenching work.
Dulles is committed to a continuous R&D path, aiming to align our high-pressure systems with the growth of green energy and smart factory automation.

A 500 bar machine is highly efficient for general cleaning, concrete roughening, and descaling soft scales. A 1000 bar (15,000 psi) system provides hydro-demolition capabilities. It has the kinetic energy required to strip tough coatings, heavy rust, thermal polymers, and baked-on chemical scale from heat exchangers and industrial pipes without chemical solvent aids.
Our pigging systems use customized polyurethane or silicone pigs that match the internal diameter (DN65 to DN125) of the pipe. Driven by nitrogen or clean air, the pig wipes the internal surface, recovering valuable lithium slurry left behind. This prevents product hardening, keeps batch contamination to a minimum, and reduces the need for frequent solvent washes.
Yes, Dulles designs and constructs custom explosion-proof cleaning systems equipped with ATEX/EX certified electric motors, non-sparking components, and pressurized safety control enclosures. These systems are specifically built for refineries, chemical factories, and offshore gas installations.
Plunger lifespan is determined by water quality, inlet filtration, and operating temperature. We use high-purity solid ceramic plungers to offer high thermal stability and wear resistance. Standard integration of 50-micron dual water filters helps protect the pump from particulate wear, significantly extending seal life.
High-capacity high-pressure units, solar wells, RO filtration systems, and robotic inspection units built to ensure operational continuity.
