Sulzer’s AHLSTAR® process pumps carry forward the engineering legacy of Ahlström Pumps, which Sulzer acquired in 2000 and folded into its own line. Built for demanding pulp & paper, mining, chemical, biofuel, and fertilizer applications, these pumps are engineered for process reliability, high efficiency, and low operating costs — with versatile hydraulics, innovative sealing, and self-priming/degassing options that handle everything from clean liquids to fibrous slurries. The Rueck Company stocks and supplies replacement parts and pumps to fit the full line of Sulzer and legacy Ahlström process pumps — APT, CPT, MCA, MCV, MCE, MPP, ZPP, and more — plus AM mixer replacements, so you’re never stuck waiting on a single source when a critical pump or mixer needs attention.
