CYQ Series Chemical Process Pump
The Changyu Pump CYQ Series Chemical Process Pump features a third-generation fully sealed magnetic drive design, eliminating the risk of mechanical shaft seal leakage associated with traditional pumps.
The pump’s wetted parts are sintered and molded from FEP/PFA-lined (fluoroplastic-lined) materials, enabling safe and stable handling of concentrated sulfuric acid, aqua regia, and flammable and explosive organic solvents. The core PEEK containment shell, combined with carbon fiber reinforcement technology, not only raises the pressure limit to 3.0 MPa but also physically eliminates eddy current losses, ensuring the pump maintains zero leakage and high energy efficiency even under harsh operating conditions ranging from -20°C to 150°C.

Introduction
Designed specifically for highly corrosive media, the CYQ series of Chemical Process Pumps incorporates a newly upgraded third-generation magnetic coupling drive technology. By utilizing contactless transmission via permanent magnets, it eliminates the need for mechanical shaft seals, thereby addressing common issues such as leakage, spillage, dripping, and seepage in industrial pumping applications at their source. The pump’s flow-through components are sintered and molded from a fluoroplastic alloy lined with FEP/PFA, enabling it to handle concentrated sulfuric acid and aqua regia, as well as various organic solvents. In particular, the core component, a Carbon Fiber Reinforced PEEK reinforcement sleeve, not only increases the system’s pressure resistance to 3.0 MPa but also eliminates the eddy current losses commonly associated with metal sleeves. This ensures the safe transfer of high-risk media while significantly improving energy conversion efficiency.
In addition to demonstrating exceptional industrial durability, this chemical processing pumps It also features high-grade NdFeB (neodymium-iron-boron) magnets in its internal magnetic assembly, combined with an advanced push-pull magnetic circuit design, resulting in powerful magnetic torque and a theoretical service life exceeding 10 years; the pump shaft is made of high-hardness Silicon Carbide (SiC), and the shaft sleeve is thickened by 4 mm, ensuring it remains stable even under harsh operating conditions involving trace particles. Whether for the transfer of highly toxic media in the chemical and pharmaceutical industries or for high-intensity operations such as eco-friendly electroplating and metallurgical acid washing, our Changyu CYQ series complies with international standards and holds ISO certification, providing global customers with fluid control solutions that meet international safety standards.
Parts of Chemical Process Pump
The CYQ Series Chemical Process Pump achieves a comprehensive upgrade—from power transmission to zero leakage of the pumped medium—through the perfect integration of “high-performance materials” and an “innovative magnetic circuit design.”
The core components are analyzed as follows: from the PEEK reinforcement sleeve, which withstands pressures up to 3.0 MPa and consumes zero power, to the NdFeB magnet assembly with exceptional torque, and the 4mm-thick SiC (silicon carbide) shaft sleeve with extreme hardness—every detail is custom-engineered for highly corrosive and high-risk operating conditions. This material selection not only ensures the pump’s long-term stability in chemical environments but also embodies Changyu Pump & Valve’s technical commitment to “zero leakage.”
Fully Lined Casing & Wetted Parts
The casing of the CYQ Series Chemical Process Pump features a high-quality carbon steel shell lined with FEP (F46) or PFA (optional or custom materials). This sintered molding process, which combines a “rigid shell with a flexible lining,” enables the equipment to withstand high pipeline pressures while offering exceptional corrosion resistance against all strong acids (such as concentrated sulfuric acid and nitric acid) and organic solvents.
PEEK Reinforcement Sleeve
As the core of the third-generation upgrade, the reinforcement sleeve is injection-molded from PEEK, a specialty engineering plastic. Compared to traditional stainless steel, it not only offers exceptional pressure resistance of 3.0 MPa but also eliminates eddy current losses, preventing the medium from vaporizing due to temperature rise. This makes it a key factor in ensuring the safe, seal-less operation of the system.
High-Performance NdFeB Magnetic Coupling
The magnetic drive system utilizes high-grade NdFeB (neodymium-iron-boron) permanent magnets and employs an advanced push-pull magnetic circuit design. Despite the minimal internal magnet volume, it delivers exceptionally strong magnetic torque. Depending on operating conditions, we offer customized solutions with temperature resistance up to 180°C (38EH) or 260°C (38AH), with magnetic performance theoretically remaining stable for over 10 years.
Thickened Silicon Carbide Shaft & Sleeve
Both the pump shaft and sleeve are made of high-purity Silicon Carbide (SiC), a material second only to diamond in hardness. Compared to industry standards, Changyu Pump has increased the sleeve thickness by an additional 4 mm, significantly enhancing the component’s impact resistance and wear resistance.
Enclosed Fluoroplastic Impeller
The impeller is manufactured using a one-piece injection-molded process with a metal insert encased in fluoroplastic, ensuring dynamic balance and mechanical strength during high-speed rotation. The enclosed structure design significantly improves hydraulic efficiency, ensuring the stability of the chemical process pump during long-distance, high-head pumping operations.
Notice: Notice: Choosing our industrial-grade CYQ series magnetic drive pumps (Chemical Process Pumps) can significantly reduce equipment downtime and lower your total cost of ownership. By utilizing an advanced seal-less magnetic drive design, Changyupump eliminates the risk of media leakage in highly corrosive environments. Combined with high-performance FEP/PFA linings and innovative PEEK reinforcement sleeve technology, our engineering solutions provide a safer, more stable, and zero-emission fluid handling environment for your most hazardous media.
