Yida Pumps Debuts YD Coaxial Self-priming Pump & CQF-Z Self-priming Magnetic Pump, Addressing Empty Suction and Hazardous Liquid Transfer Challenges Worldwide

WENZHOU, July 24, 2026 – As industrial wastewater treatment and mineral processing industries expand across emerging markets, demand for self-priming anti-corrosion pumps surges globally. Traditional chemical pumps require pre-filling liquid before startup and easily suffer dry-run breakdowns, increasing factory downtime and maintenance costs. To resolve these industry pain points, Zhejiang Yida Pump Industry launched two proprietary self-priming pump products: YD coaxial self-priming acid pump and CQF-Z self-priming magnetic pump.

The YD series coaxial self-priming pump adopts an integrated self-priming chamber structure, realizing stable self-suction height without installing bottom valves on pipelines. The whole pump body is molded with thickened anti-corrosion plastic, resisting hydrochloric acid, sulfuric acid, sodium hydroxide and various electroplating waste liquids. Its coaxial direct-coupled motor simplifies the transmission structure, cutting volume and installation space for compact chemical workshops, electroplating production lines and municipal waste liquid collection stations.

The CQF-Z self-priming magnetic pump innovatively combines Yida’s mature magnetic drive sealless technology with self-priming hydraulic design. It retains the core zero-leakage merit of magnetic pumps while adding strong self-suction capability, making it ideal for transferring volatile, toxic corrosive chemicals where both suction performance and emission control are mandatory. Unlike metal self-priming pumps prone to chemical corrosion, all liquid-contact parts of CQF-Z adopt FRPP/PVDF composite materials, extending service life in harsh chemical environments.

Global market research indicates the corrosion-resistant self-priming pump market maintains steady growth fueled by stricter wastewater discharge standards in Europe, Southeast Asia and Latin America. Most mainstream self-priming pump products on the market are metal-based with weak anti-corrosion performance, while imported plastic self-priming pumps carry high procurement costs. Yida’s YD and CQF-Z series balance anti-corrosion performance, self-priming efficiency and competitive pricing, bringing cost-down options for mid-sized chemical enterprises worldwide.

Yida’s engineering team optimized the pump internal flow channel through repeated fluid simulation testing, reducing internal resistance and improving energy efficiency by 12% compared with conventional self-priming plastic pumps. Both models support 380V industrial three-phase power supply and can be equipped with explosion-proof motors for petrochemical and hazardous waste treatment scenarios.

Overseas clients from Indonesia chemical parks, Thailand electroplating factories and Poland wastewater treatment plants have placed trial orders for the new self-priming pump series, with positive feedback on stable suction performance and low failure rates during continuous operation.
