Motorbox for Ø 90 m Decanter

Power and Precision in Managing Large-Scale Fluid Masses

When it comes to water and sludge treatment on an industrial scale, the need for mechanical reliability, transmission power, and dynamic control becomes crucial—especially in large-diameter systems.
The motorbox for a 90-meter decanter is designed to ensure continuous, synchronized, and safe movement of the rotating system, even under critical loads and in corrosive environments.

The Mechanical Core of a High-Capacity Plant

Reliable, powerful, and customizable: the motorbox for a 90-meter decanter is the dynamic heart of a high-capacity sedimentation plant.
It is a solution built to last and operate without interruption, even in harsh environmental conditions, guaranteeing the perfect balance between mechanical efficiency and industrial control.

Technical and Functional Performance

The motorbox is designed to:

  • Withstand high axial and radial loads

  • Allow continuous, controlled rotation at extremely low speed

  • Operate 24/7 with minimal maintenance requirements

  • Be compatible with torque monitoring and mechanical safety systems

Its modular characteristics make it suitable for both new installations and revamping of existing plants.

Technology Applied to Detail

The equipment integrates:

  • An automated handling system for the precise positioning of the jack and the cable

  • A welding module with temperature and cycle-time control

  • Vision sensors and verification algorithms for alignment and connection integrity

All of this is orchestrated by a central control unit that manages parameters, cycles, and real-time diagnostics.

Industrial Advantages

  • Oversized planetary gearboxes: High torque even at low speed

  • Self-supporting structure: Easy assembly and inspection

  • Internal ring gear: Smooth and stable transmission

  • Sensor compatibility: Ready for predictive maintenance

  • Modular construction: Installation in demanding or existing environments

Integrated Mechanical Architecture

The system consists of a main supporting structure integrating:

  • Multiple planetary gearboxes sized for high torque loads

  • Transmission system with internal ring gear

  • Upper bearing assembly with reinforced arch structure

  • Vertical guides and supports for sliding and settlement compensation

The entire architecture is designed to optimize the dynamic balance of the system and reduce local stresses on the concrete structures of the basin.
