Taco Single-Stage, Double-Suction Horizontal Split Case Pumps (TA Series)
Heavy-duty centrifugal pumps with efficient double-suction impellers and modular construction for reliable water circulation and easy maintenance.
Taco Single-Stage, Double-Suction Vertical Split Case Pumps (TS Series)
- Taco TS pumps combine a vertical split casing with a high-efficiency double-suction impeller. Side suction and top discharge connections minimise installation space. A dry shaft design, replaceable wear components and accessible casing simplify maintenance, while the double-suction arrangement reduces axial thrust and bearing loading.
- Sizes: 3–14 inches.
- Performance: 70–11,000 GPM; 10–560 ft head; 2–800 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: Up to 250°F (120°C).
- Connections: ANSI Class 125 flanges; optional Class 250.
- Casing: ASTM A48 Class 30A cast iron with integral mounting feet.
- Impeller: Bronze; optional AISI 304 stainless steel.
