Taco Close-Coupled End Suction Pumps (CI / SCI Series)

  • Taco CI pumps combine a compact, close-coupled design with a self-venting, top centerline discharge. Rear pullout construction allows servicing without disturbing system piping, while a dry shaft and replaceable shaft sleeve simplify maintenance. SCI SelfSensing versions offer integrated variable-speed control and ProBalance® system balancing. Optional ECM motor packages improve energy efficiency.
