Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

For the water and wastewater treatment industry, Tianjin Uranus Hydraulic Machinery Co., Ltd. offers custom hydraulic cylinders that provide reliable actuation for gates, valves, screens, and sludge handling equipment. These cylinders must resist corrosion from moisture, chemicals, and biological agents, and operate in wet or submerged conditions. As a national high-tech enterprise with over 30 years of experience, we design cylinders with stainless steel components, specialized coatings, and robust seal systems to ensure long service life in these challenging environments. Our custom cylinders for sluice gates and weirs are typically large, with strokes up to 10 meters. They are often required to operate under water or in partially submerged conditions. We use 316L stainless steel for the rod and cylinder body, or we apply a heavy-duty epoxy coating over carbon steel for a more economical solution. The seal system includes multiple wipers and scrapers to prevent ingress of debris. For a municipal water treatment plant in China, we supplied 12 custom gate cylinders with a bore of 100 mm and a stroke of 3,000 mm. The cylinders are equipped with position sensors to provide feedback to the SCADA system. They have been operating for over 12 years with only routine maintenance. For screen cleaning equipment, we provide custom cylinders that drive rakes or brushes. These cylinders cycle frequently and are exposed to abrasive grit and debris. We use hard chrome-plated rods, bronze bearings, and heavy-duty polyurethane seals. For a UK wastewater treatment plant, we supplied custom cylinders for a step screen cleaner, operating at 20 cycles per hour, 24/7. The cylinders have achieved a service life of over 2 million cycles. For sludge press equipment, such as filter presses, our custom cylinders generate high forces to dewater sludge. These cylinders have large bores (up to 400 mm) and short strokes, operating at pressures up to 300 bar. We use forged components and high-strength tie rods. For a French sludge treatment company, we provided custom cylinders for a recessed plate filter press, with a clamping force of 500 tons. The cylinders are equipped with automatic pressure maintenance systems and have been in service for over 7 years. Our manufacturing process includes 100 percent non-destructive testing of critical welds, pressure testing, and functional testing with water or oil. We provide a detailed test report and a five-year warranty on the rod coating. For a custom cylinder for your water or wastewater application and a quote, please contact our engineering team.
