RIPTIDE™ Direct-Drive Surface Mixer

Reliable, low-maintenance water mixing at nearly any angle

With its rugged construction and low-maintenance design, the RIPTIDE® direct-drive surface mixer delivers dependable and economic performance mounted at a wide range of angles.

Featuring a high-efficiency, slow-speed propeller, the Riptide combines all or part of a basin with rugged construction that can withstand most applications. All mixing action takes place just below the surface, which means no spraying and no splashing.

Maximum Dependability, Minimal Maintenance

State-of-the-art engineering and meticulous construction specifications ensure that the Riptide surface mixer will run correctly from the beginning and keep running without time-consuming maintenance. The subsurface propeller will not foul, even in heavy solids. A double row of bearings securely supports the mixer shaft, preventing vibration and absorbing all propeller thrust loads while the slow speed extends the motor life and increases mixing efficiency.

Riptide's features contribute to long-lasting performance:

  • Corrosion- and UV-resistant stainless-steel construction throughout
  • Solid shaft, vibration-free design
  • Sealed ball bearings
  • No-maintenance mechanical seals
  • Simplified motor change-out and motor-shaft coupling
  • Weedless propeller

We factory test each Riptide direct-drive surface mixer to ensure the equipment meets Fluence's stringent standards.

The Riptide Is Flexible for Optimal Mixing

The Riptide is ideal for wastewater treatment and supplemental mixing, providing complete basin design flexibility. Fully adjustable mounting on floats or brackets means complete mixing of a basin of any depth or shape and makes it simple to direct mixing toward a deficient area. Angle-adjustment locking bolts allow optimization of mixing velocities to ensure a strong mixing action.

Available models range between 2-20 horsepower (1.5-15 kW). Options for high-efficiency and premium-efficiency C-face motors increase the system's design versatility. Fluence can recommend configurations that best match your requirements.
