Taco Frame-Mounted End Suction Pumps (FI / SFI Series)

Mostafa Refaay — Wed, 30 Sep 2026 14:09:28 +0000

Taco FI pumps feature a rigid steel base, flexible coupling and sealed-for-life bearings for stable operation and simplified maintenance. The top centerline discharge provides self-venting, while rear pullout construction allows servicing without disturbing system piping. A dry shaft design and replaceable shaft sleeve protect components and simplify seal replacement. SFI SelfSensing versions provide integrated variable-speed control and ProBalance® balancing; optional ECM packages improve energy efficiency.
