Special water intake scenarios such as mines, saline-alkali lands and chemical industrial areas feature unbalanced pH values and highly corrosive impurities, which easily cause pump body corrosion, component aging and performance attenuation of ordinary deep well pumps. To expand the equipment’s adaptability to diverse working conditions, Jinyu Pump has completed special iteration of material anti-corrosion technology and innovatively adopted a composite technology of precision stainless steel forging and multi-layer anti-corrosion coating. Core components including the pump body, impeller and pump shaft are made of high-purity stainless steel with precision forging technology to improve material density and strength. The nano anti-corrosion coating on the surface effectively resists acid-base corrosion, water oxidation and sediment wear. Verified by professional acid-base corrosion tests and salt spray aging tests, the anti-corrosion and anti-aging performance of Jinyu Pump far exceeds industry standards. It can operate stably in harsh working conditions such as saline-alkali water, slightly polluted water and complex mine water, breaking the industry dilemma of easy damage to water intake equipment in special scenarios with advanced anti-corrosion technology.
