The metallurgy and smelting industry requires pumps that can handle high-temperature, corrosive, and abrasive media such as acid pickling solution, slag slurry, and metal ion wastewater. Our UHB slurry pumps and corrosion-resistant chemical pumps provide stable operation in harsh environments, ensuring long service life and reliable process performance.

The energy and chemical industry encompasses petrochemical, coal chemical, and biomass conversion sectors, dealing with challenging conditions such as high temperature, corrosion, and flammable media. For transferring thermal oil, acidic liquids, and slurries, we offer tailored pump solutions, including Magnetic Drive Pumps, Hot Oil Pumps, and UHB Slurry Pumps etc.

Environmental protection and wastewater treatment processes involve corrosive liquids, high-viscosity slurries, and solid-laden fluids. Our pumps are designed for long-term operation in clarifiers, neutralization tanks, leachate systems, and sludge handling, providing stable and efficient fluid transfer.

Chemical processing requires pumps capable of handling acids, alkalis, solvents, corrosive liquids, polymers, and abrasive slurries. Changyu’s pump products provide reliable sealing, corrosion resistance, and wear resistance to ensure safe and continuous operation in critical chemical units.

Bio-acid production involves corrosive liquids, organic acids, fermentation liquids, and solid-containing slurries. Our corrosion-resistant UHMWPE and slurry pump series are well-suited for biological fermentation, extraction, concentration, and wastewater treatment processes.

The textile dyeing and finishing industry uses large volumes of dyes, auxiliaries, acids, alkalis, and wastewater containing suspended solids. Our corrosion-resistant pumps ensure stable transfer for dye solution preparation, wastewater treatment, and chemical dosing systems.

The pulp and paper industry requires pumps that can handle high concentrations of fiber slurry, corrosive bleaching liquids, alkali solutions, and wastewater. Our UHB slurry pumps and corrosion-resistant chemical pumps provide reliable performance in harsh pulp processing environments.

Coking operations generate corrosive and abrasive liquids, such as ammonia water, phenol-containing wastewater, tar-containing slurry, and high-temperature wash water. Our corrosion-resistant and abrasion-resistant pumps perform well in coke oven gas washing and wastewater treatment units.

Mining processes involve highly abrasive slurries with large particle sizes, tailings slurry, mineral separation liquids, and acidic or alkaline process fluids. UHB slurry pumps in particular are ideal for continuous heavy-duty operation in mineral processing plants.
