The Riptide direct drive surface mixer, with its rugged construction and low-maintenance design, delivers dependable and economical performance mounted at a wide range of angles.

The Riptide provides directional mixing.

RWL Water’s Riptide surface mixer provides directional mixing and can be mounted at many angles.

The Riptide direct drive surface mixer delivers dependable and economical performance when mounted vertically, nearly horizontally, and anywhere in between. Featuring a high-efficiency, slow-speed propeller, the Riptide is directional, mixing all or part of a basin. Its rugged construction 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 runs correctly from the beginning and keeps 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, which helps extend motor bearing life. Slow speed (900 rpm at 60 Hz or 750 rpm at 50 Hz) extends life and increases mixing efficiency.

Additional features contribute to long-lasting performance, including:

  • 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

Each Riptide direct drive surface mixer is factory tested, ensuring the equipment meets RWL Water’s stringent standards for quality.

Mounting angle ranges from vertical to near-horizontal.

The Riptide has a solid shaft for vibration-free design.

The Riptide Is Flexible for Optimal Mixing

The Riptide is ideal for wastewater treatment and supplemental mixing, providing complete basin design flexibility. It can be mounted vertically, or nearly horizontally in the water, with the motor above the surface turning the propeller below, via a solid shaft. Angle adjustment locking bolts allow optimization of mixing velocities to ensure a strong mixing action.

Fully adjustable mounting on floats or brackets allows for complete mixing of a basin of any depth or shape, and makes it simple to direct mixing toward a deficient area.

Models are available from 2-30 hp (1.5–30 kW). High-efficiency or premium-efficiency standard C-face motors increase the system’s design versatility. RWL Water can recommend configurations best suited to your application.

Riptide can be float-mounted.
