Gratt Hyperbolic Stirrer: Efficiency, Low Consumption and Durability.
The definitive solution for the homogenization of equalization tanks, reservoirs and lagoons. Designed for intensive use in water and wastewater treatment plants, it combines structural robustness with precision engineering for maximum energy efficiency.
Emphasis: Ideal for ensuring complete and constant mixing of liquids with suspended solids.
How does it work?
- Flow Mechanics: It uses a turbine with curved blades positioned close to the bottom of the tank, creating a downward flow that directs the liquid from the surface to the bottom.
- Elimination of Dead Zones: This design promotes intense recirculation, eliminating dead zones and keeping solids suspended.
- Optimized Power: Powered by a low-speed, high-torque gearmotor, it moves large volumes of liquid with low installed power.
Advantages of the Gratt Hyperbolic Stirrer
Engineering and Maintenance Differentials
- Extended Service Life: The shaft drive system connected to a gear motor is positioned above the liquid level, avoiding direct contact with the fluid and drastically reducing maintenance frequency.
- Mechanical Stability: The design features a tubular axle and crossheads with robust bearings that compensate for misalignments and minimize vibrations.
- High Quality Materials: Structure and shaft available in carbon steel or stainless steel, with rotor in GRP (fiberglass) or 304 stainless steel.
Applications
The Hyperbolic Stirrer is the ideal choice for:
- Water Treatment Plants (ETA) and Sewage Treatment Plants (ETE).
- Equalization tanks, facultative and anaerobic lagoons.
- Activated sludge systems and anoxic selectors.
- Homogenization of liquids in various industrial processes.
