Featuring Centrate Diverters, Diverter Chutes, Pneumatic Slidegates and Plug Breakers

Advanced Flow Control Solutions for Sludge and Solids Material Handling

In wastewater treatment plants and industrial processing systems, precision and reliability in material flow control are essential. Our range of Centrate Diverters, Diverter Chutes, Pneumatic Slidegates and Plug Breakers are engineered to optimize efficiency, reduce downtime, and protect downstream equipment. 

Our flow control equipment is designed to meet the rigorous requirements of modern processing systems.

Centrate Diverters: 

Precision-engineered systems for managing centrate flows. Commonly used in sludge dewatering processes such as with centrifuges, belt filter presses, and decanters, these diverters handle high-volume liquid streams with minimal wear. They ensure reliable operations in demanding environments where the controlled redirection of centrate is required for further treatment or safe discharge.

Diverter Chutes: 

Built for controlled redirection of solids or liquids, this chute is robust and adaptable. It integrates seamlessly with other SPIRAC systems and is ideal for facilities requiring efficient flow management.

Pneumatic Slidegates: 

These gates are widely used across our installations. The pneumatic U620 model offers automated control and is available in various configurations, including 90° layouts. Known for reliability and ease of integration, slidegates are essential for flow regulation in solids handling systems.

Plug Breakers:

Our plug breakers are designed to break up compacted material, ensuring smooth flow through conveyors or chutes. Available in multiple configurations, they can be tailored to suit specific operational needs. Our plug breakers are ideal for integration with shaftless spiral conveyors and screenings dewaterers and compactors. 

Custom configurations are available to suit specific operational layouts, material types and throughput requirements. 

Talk to us today to find out how our Flow Control Solutions can be tailored to your facility’s needs.

PRODUCT BENEFITS

Custom configurations are available to suit specific operational layouts, material types and throughput requirements.

Centrate Diverters features include:

  • Automated actuation (typically pneumatic or electric) for responsive flow redirection.
  • Corrosion-resistant construction to withstand aggressive chemical environments.

Diverter Chutes features include:

  • Custom geometries to suit specific plant layouts and flow rates.
  • Actuated flaps or gates for dynamic switching between discharge points.

Pneumatic Slidegates features include:

  • Fast cycling times for high-throughput operations.
  • Modular configurations for easy integration into existing systems.

Plug Breakers features include:

  • Oscillating mechanisms that use lateral motion to dislodge material and create plugs to maintain flow continuity.
  • Robust construction using wear-resistant materials to withstand abrasive and corrosive environments.
