Applications
Decanter Centrifuge with Centripetal Pump Discharge: industrial applications
Applications include chemical and pharmaceutical processing and environmental and resource processing. Confirm material properties and process conditions before selecting the equipment configuration.
Environmental and resource processing
Wastewater, sludge, mineral and energy-industry streams requiring continuous solids removal.
Food and related industries
Food-process liquids and other applications requiring high recovery, low clarified-liquid solids and separated phase discharge.
Suitable process duties
High-throughput, continuous processes requiring flexible differential-speed control, robust wear resistance and low solids carryover.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Feed distribution
Feed enters continuously through the feed pipe and is accelerated and distributed into the rotating bowl.
Centrifugal sedimentation
The density difference drives solids to the bowl wall, where they form a sediment layer beneath the inner liquid pond.
Differential scroll transport
The scroll rotates at a controlled differential speed and conveys settled solids toward the conical section.
Cone dewatering and solids discharge
Solids are further dewatered on the cone and continuously discharged through the solids ports.
Pressurized liquid discharge
Clarified liquid flows to the large-diameter end and is discharged under pressure by the centripetal pump.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Large L/D bowl
The operating range is selected for the material and confirmed for the quoted configuration.
High product recovery
The operating range is selected for the material and confirmed for the quoted configuration.
Pressurized clean-liquid route
The centripetal pump provides pressurized mother-liquor discharge, while separated liquid and solids chambers support cleaner product handling.
Flexible process control
Independent bowl and scroll drives permit online differential-speed adjustment to stabilize clarification, dewatering and solids discharge.
Energy recovery
The common-DC-bus drive can recover usable energy and reduce overall electrical demand.
Long-life wear protection
Replaceable wear components protect the scroll flights, solids outlets and other erosion-prone areas, reducing lifecycle maintenance.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Centripetal-pump discharge
The centripetal pump discharges clarified liquid under pressure and may reduce or eliminate a downstream transfer pump, depending on system pressure requirements.
Separated phase outlets
Liquid and solids leave through separate chambers, reducing the centrifuge of mother-liquor droplets recontacting discharged solids.
Dual-motor, dual-VFD drive
Separate drives for the bowl and scroll provide responsive differential-speed adjustment as feed conditions change.
Common DC bus
An optional common-DC-bus regenerative drive recovers part of the energy generated during differential or braking operation.
Optimized scroll
A streamlined flow path reduces feed impact, buildup and blockage while supporting stable solids transport and lower clarified-liquid solids.
High-strength rotating assembly
Centrifugally cast critical rotating components provide strength, reliability and stable long-term operation at high speed.
Wear-resistant construction
Scroll flights and high-wear zones can use carbide, embedded carbide blocks, wear-resistant ceramics and replaceable liners or outlet sleeves.
Self-cooling bearing housing
A high-rigidity, self-cooling bearing housing supports bearing heat dissipation and reliable continuous operation.
Reduced scroll loading
The conveying geometry is optimized to reduce friction, scroll torque and adhesion of sticky solids.
