In the alkaline liquor transfer service of inorganic chemical industry, the medium is mostly high-temperature alkaline aqueous solution, which tends to precipitate salt crystals. Challenges such as stress corrosion, crystal jamming, leakage and seepage are commonly encountered. Anhui Guotai Pump Technology specializes in chemical fluid transfer. For alkaline liquor transfer applications, chemical centrifugal pumps and cam rotor pumps are available, with a variety of customized wetted parts materials including 2205 duplex stainless steel. Our pumps effectively resist strong alkali corrosion and mitigate crystal blockage, delivering stable and reliable auxiliary fluid transfer equipment for processes such as chlor-alkali and inorganic salt production.

Hydrochloric acid is a strongly reductive acidic medium with extremely high corrosivity, which cannot be resisted by ordinary stainless steel. In some process conditions, hydrochloric acid contains trace solid impurities and is volatile. Leakage will form corrosive acid mist, imposing strict environmental and safety requirements. Anhui Guotai chemical centrifugal pumps and cam rotor pumps are equipped with special corrosion-resistant wetted parts and reliable sealing structures. Featuring excellent medium adaptability, our pumps are widely used for synthesis process feeding, pickling section circulation, waste acid transfer, acid unloading from tank trucks and liquid transfer in acid tank farms.

Brine features high chloride ion and salt concentration, which readily precipitates salt crystals and causes chloride pitting corrosion on equipment. The medium often carries sediment and crystal particles, commonly used in the front-end processes of chlor-alkali, salt-making and inorganic salt production. Common failures include salt scaling on impellers and flow passage blockage. Anhui Guotai chemical centrifugal pumps deliver good resistance to chloride pitting corrosion. Adopting a semi-open impeller structure, the pumps reduce salt crystal adhesion and blockage. For sediment-laden brine service, wear-resistant materials are available to withstand erosion by solid particles. They are widely applied in salt mine brine lifting, pretreatment feeding, brine circulation, crystallization process feeding, and brine transfer to electrolysis sections.
