Suction Barrels of the vertical turbine pump

The suction barrel is a vertical turbine pump installation type that provides a preconfigured vertical turbine pump casing. See Figure 4 for reference. This casing is usually provided and designed by the factory. Since the design of the casing will impact vertical turbine pump performance and longevity, any casing provided by others must be reviewed and approved by the factory or the vertical turbine pump warranty will be void.

The barrel may be installed above ground, below ground with anti-flotation countermeasures, or encased in concrete. In all cases, the barrel must be straight, with the top flange level within 0 to 0.005 inches perlinear foot.
