Overview

  • KOOI Big White Series pumps use a submersible axial-flow design for high-volume circulation in systems with small elevation differences. The range includes seven models, with power ratings from 100 to 500 W, model-specific maximum flow rates from 45 to 120 m³/h and maximum heads from 0.55 to 1.8 m. Maximum flow and maximum head describe separate operating limits.
  • The series supports freshwater and seawater applications and features a 110 mm pipe connection. Applications include koi ponds, aquaculture facilities, river-style circulation channels and circulation systems used for zooplankton harvesting. The specified dimensions are 215 × 180 × 350 mm, with a 5 m cable.
  • Variable-frequency operation is paired with protection against lightning surges, electrical interference, dry running and locked-rotor conditions.
