Flow Optimizer Vaned Eccentric Reducers

Optimized Flow and Air-Free Performance: Eccentric Reducers & Vaned Eccentric Reducers for Pumping Systems

Eccentric reducers are used in pump suction & discharge piping systems to connect two pipes of different diameters. Unlike a concentric reducer which resembles a cone, eccentric reducers have a flat, parallel edge creating an asymmetrical flow condition.

Standard engineering practice use horizontal eccentric reducers with the flat side on the top, to prevent the build-up of air bubbles in the system. The gradual accumulation of air in a concentric reducer could result in a large bubble that could eventually cause the pump to lose prime or cause cavitation.

Key Benefits:

Eccentric Reducers

  • Ensure air does not accumulate in the pipe.
  • Connect pipes of different sizes.
  • Facilitate transition from large diameter suction piping to smaller pump suctions.
  • Prevent air pockets in high points of the pipes which will cause cavitation and damage to the pump.

Vaned Eccentric Reducers

  • All the benefits listed above plus flow conditioning.
    • Eliminate flow separation resulting from an upstream elbow.
    • Pipe flow becomes distributed evenly to ensure uniform flow distribution entering the eye of the impeller.
    • Reduces noise.
    • Helps to eliminate unbalanced loads.

Applications:

  • To be used on all horizontal pumping systems.
  • Recommend mounting the concentric or eccentric reducers at least 5 diameters.
  • Length & vane spacing to be Engineered as “custom” for every size, reduction, & application.
