Taco Single-Stage, Double-Suction Horizontal Split Case Pumps (HS Series)

  • Taco HS pumps feature a heavy-duty split casing and a hydraulically and dynamically balanced double-suction bronze impeller. Bearings and mechanical seals can be serviced without removing the top casing, while the removable upper casing provides access to the rotating assembly without disturbing piping. A short, rigid shaft reduces deflection, seal wear and bearing loading.
  • Models: HS060509, HS060511, HS060512 and HS060515.
