Submersible Slow-speed Agitator

The Submersible Slow-speed Agitator is a submersible, low-speed propulsion device for large-scale water circulation and solid-liquid mixing, suitable for applications such as wastewater treatment and biological tank mixing.

For example:
ST1800.52-M4/5.5R-G/C/S

ST – Series name
1800 – Impeller diameter (mm)
52 – Blade rotational speed (r/min)
M – Motor configuration
4 – Motor poles
5.5 – Motor power (kW)
R – Reducer connection type (R = With reducer)
G – Blade material (G = Fiberglass; P = Polyurethane)
C – Agitator body material (C = Carbon steel)
S – Mounting system material (C = Carbon steel; S = 0Cr19Ni9; T = 022Cr17Ni12Mo2)

High Thrust Output

A large-diameter, low-speed impeller combined with optimized hydrodynamic profiles achieves higher thrust and more uniform flow field coverage.

IP68 Sealing Structure

The integral cast housing with multiple mechanical seals has passed IP68 testing and can operate reliably in water up to 20m deep for extended periods.

F/H Class Insulation Motor

Utilizing F-class insulation (H-class optional), the motor's temperature resistance is 25–50℃ higher than B-class, ensuring stable lifespan under S1 continuous operating conditions.
