Description
QJB Submersible Flow-maker 2.2 kW – Low-Speed Flow Booster for WWTP Circulation
The Lanjiang QJB Flow-maker 2.2 kW is a compact yet capable low-speed propelling flow mixer, bridging the gap between entry-level and mid-range flow-boosting requirements. It is especially well suited for small WWTP oxidation ditches, denitrification basins, and anoxic zones where moderate flow energy is needed to maintain solids in suspension.
Key Features
  • PUR impellers available in Ø1,100 mm, Ø1,400 mm, or Ø1,800 mm configurations
  • Delivers thrust of up to 1,870 N for effective circulation
  • Helical-bevel gearbox ensures quiet, vibration-free operation
  • Low-speed operation (42-52 r/min) creates gentle yet powerful bulk flow
  • Circulates entire basin volume with minimal energy input
