Engineered for extreme reliability under industrial workloads. Explore our primary product lines featuring cutting-edge high-pressure dynamics, diagnostics, and purification engineering.
Foshan Dulles Equipment Co., Ltd. was great experienced in cleaning mechanical system research and development for more than 30 years, which was one of the earliest companies to produce pressure washers. As the growing market greatly demand of clean and environmental products year by year, we speed up research and development work meanwhile commit to provide multi-aspect cleaning and environmental solutions to our customers. Early in 1995, the first general home pressure washer was developed. In order to meet the different requirements from market demand, we continue to develop products which involve commercial and industrial pressure washers, explosion-proof high pressure cleaning machines, sewer machine drain cleaners, fog making machines, electric sewer cleaners, gasoline dredge cleaning machines, as well as intelligent fog making machines, etc.
Understanding the intricacies of hydraulic configurations has allowed Dulles to scale technology from consumer home pressure units to robust industrial multi-plunger pumps. Today, our engineering focus incorporates advanced flow dynamics, IoT integration, and cavitation management. This ensures that every high-pressure system operates at optimal thermal and kinetic efficiency, reducing utility costs for corporate partners while extending system service life.
From maritime ship rust removal to deep municipal sewer operations, we provide tailored fluid solutions that withstand tough industrial environments.
Our products are widely applied in various areas, especially in industrial and chemical production, ship rust removal, municipal bridge engineering, mine and road dust removal, street cleaning, urban pipe dredging, and mobile car wash equipment, etc. The series products have obtained 3C, CE and ISO certificates, and also design pattern certificates for pressure washers, high pressure pumps, fog making machines and more. Dulles products are well accepted by the market with advantages of unique and fashionable design, cost-effectiveness, high-level safety and stable performance, which has helped build a strong reputation and expand gradually into European and American markets from South and East Asia.
With global environmental guidelines targeting water waste and chemical runoff, Dulles engineering integrates closed-loop water treatment filters and high-efficiency cavitation nozzles. Our units deliver up to 40% higher cleaning power per gallon, enabling heavy chemical production facilities and municipal entities to decrease detergent dependency and satisfy strict local discharge codes.
Precision-controlled concrete washing and paint ablation using up to 210bar configurations, ensuring structural inspection safety without damaging structural steel or concrete integrity.
Specially designed explosion-proof configurations prevent gas combustion while effectively dissolving petroleum residues, calcium deposits, and chemical crusts.
Automated intelligent fog machines designed for dust suppression and livestock temperature regulation, combining high pressure with micron-level atomization.
The company owns a self-built laboratory, automated assembly lines, and high-precision testing instruments and equipment to ensure the safety, long service life, and stable quality of each finished product. Our professional team provides 7×24-hour pre-sales, sales, and after-sales service to respond promptly to every inquiry with professional solutions and effective communication.
Behind every triplex plunger pump lies a testing protocol. From incoming material analysis (using metallurgical spectrometers) to mechanical endurance runs under simulated overload conditions, we target zero-defect manufacturing. Our lab engineers test seals, bypass valves, and electrical insulation levels under high temperatures. By prioritizing structural analysis and hydrodynamic simulation, we ensure our pump casings prevent structural failure even when subjected to intense backpressure pulses.
Our automated assembly lines integrate precision torque tools and visual inspection cameras. This guarantees that all fasteners, crankcases, and ceramics align perfectly, minimizing vibration and reducing heat generation during extended continuous use.
Bridging advanced engineering institutions with real-world cleaning demands to develop smart and reliable environmental equipment.
We are now cooperating with globally recognized research and development institutions both at home and abroad, and will continue to deliver better products to the market through innovation and development in the field of cleaning and environmental protection. We promise to do our best to clean the world and create a smarter life, and we will grow together with partners worldwide to build a most reliable global brand in the cleaning and environmental protection industry.
Looking forward, our R&D roadmap targets the integration of intelligent digital platforms into heavy industrial sprayers. By embedding pressure sensors, digital flow meters, and vibration transmitters, our systems will offer predictive maintenance alerts to users. Operators can monitor pump health, fuel consumption on diesel models, and seals wear directly via an app, minimizing downtime and optimizing performance in the field.
