Taco Vertical In-Line Pumps (KV / SKV Series)

  • Taco KV pumps provide efficient circulation in a vertical in-line arrangement that saves space and requires no isolation pads. Hydraulically balanced impellers reduce bearing loading, while a dry shaft design, replaceable shaft sleeve and seal flush line simplify maintenance. SKV SelfSensing versions offer integrated variable-speed control and ProBalance® balancing; optional ECM packages improve energy efficiency.
  • KV sizes: 1½–8 inches.
  • KV performance: 10–2,650 GPM; 11–385 ft head; ¾–60 HP, depending on model.
  • Working pressure: Standard 175 PSIG (1,210 kPa); optional 300 PSIG (2,070 kPa), subject to pressure–temperature limits.
  • Fluid temperature: Standard 250°F (120°C); optional 300°F (149°C) configuration.
  • Connections: Equal-sized suction/discharge ports; ANSI Class 125 flanges, optional Class 250.
  • Casing: Cast iron; ductile iron casing for Class 250 construction.
  • Impeller: Bronze or stainless steel, depending on construction.
  • Shaft: Carbon steel with replaceable bronze sleeve; optional Type 303 stainless steel sleeve.
  • Seal: Ceramic/EPT standard; optional tungsten carbide or silicon carbide.
  • Seal protection: Factory-installed vent/flush line and bronze throttle bushing.
  • Motor: Standard NEMA JM frame.
  • Service provisions: Back pullout construction, suction/discharge pressure taps and casing drain.
