Industries & Applications for Magnetic Drive

Lead acid battery manufacturers use magnetic drive pumps to transfer sulfuric acid (93% to 98%, depending on the season) from outdoor bulk storage tanks to indoor blending tanks. Magnetic drive pumps can also transfer deionized water into the blending tank to achieve the proper dilution for battery acid (typically 29% to 32% sulfuric acid).
