CQF & CQF-Z Self-Priming Magnetic Pump Series Realize Stable Self-Suction 5m Without Bottom Valve, Favored by Global Wastewater Treatment Enterprises

June 10, 2026 – Shanghai, China

Self-priming corrosion-resistant pumps are in short supply in the global wastewater treatment sector, as most mainstream magnetic pump products cannot complete self-suction without bottom valves, increasing construction and maintenance costs for overseas environmental projects. YD Pumps released optimized CQF and CQF-Z self-priming magnetic pump product lines, combining magnetic drive zero-leak advantage with powerful self-suction performance, achieving a breakthrough in export-oriented pump technology.

CQF horizontal self-priming magnetic pump integrates a large-capacity self-priming cavity, which can continuously suck corrosive wastewater from underground pools without pre-filling liquid, with a maximum self-suction height of 5 meters. CQF-Z vertical integrated self-priming magnetic pump further compacts the overall structure, saving 30% installation space compared with horizontal models, ideal for compact electroplating workshop and small wastewater station layouts. Both series adopt fluoroplastic corrosion-resistant flow channels, resisting chromic acid, hydrofluoric acid, waste lye and heavy metal wastewater, completely avoiding toxic liquid leakage that violates EU environmental discharge standards.

In field tests at a PCB factory in Bangkok, Thailand, CQF-Z pumps operated continuously for 2,000 hours without suction failure or liquid leakage. The customer canceled the original bottom valve and liquid storage tank design, cutting overall pipeline investment by 22%. All products comply with RoHS, CE and international wastewater equipment safety standards, supporting customized voltage (220V/380V/415V) for European, American and Southeast Asian power grids.

Industry analysts pointed out that with the global acceleration of industrial wastewater renovation projects, self-priming magnetic pumps will become a high-growth subdivision track. YD Pumps’ CQF and CQF-Z series will rely on cost-effective integrated design to expand market share in Latin America and Southeast Asia, and support customized material configurations for high-corrosion special medium working conditions.
