Challenge

Trench wet well applications can introduce undesirable hydraulic conditions at the
pump suction, including:

  • Uneven velocity distribution
  • Turbulence entering the pump intake
  • Inconsistent flow conditions at suction

Solution:

Flow Optimizers provided custom engineered Vaned Pump Suction Extension Bellmouths
to support improved hydraulic conditions at the pump suction within the trench wet well.

  • Optimized inlet geometry to promote stable flow into the pump
  • Improves velocity distribution at the pump suction
  • Supports more consistent hydraulic performance
  • Fabricated to integrate with the existing wet well configuration

Benefits

  • Improved hydraulic conditions at pump suction
  • Stabilized flow entering the pump intake
  • Reduced turbulence and flow disturbances
  • Enhanced operational reliability
  • Designed for trench wet well configurations
  • Bellmouth sizes 3”,4”,6”,8”,10”, &12” in stock (Flanged).
  • Bellmouth sizes14” & 20” in stock (without Flanges).
  • Bellmouth sizes 16” & 18” late 2026.
  • 24” is investment cast pattern made & waiting for orders (without flanges).
  • With or without Flanges
    • Bolt Circle: both ANSI & DIN.
    • Drawings available online.
    • Material is 316 Stainless Steel AIS – BABA Compliant.
    • Designed per Hydraulic Institute.
