Feed and Accelerate
Contaminated coolant or compatible oil enters the rotating tubular bowl and accelerates with the separation zone.

Automatic Sludge Discharge Centrifuge for Continuous Production
An automatic sludge discharge centrifuge separates metal fines and sludge, then removes collected solids through a controlled discharge cycle—without disposable filter media in the centrifugal separation stage.

Choose an Automatic Sludge Discharge Centrifuge
The four core VC models cover rated flows from 60 to 200 L/min. Selection is based on more than flow: G-force, solids capacity, fluid viscosity, contaminant density, required sump turnover and discharge frequency must be reviewed together. Open a model page for its detailed specifications and inquiry route.
VC-600E enclosed configuration: it uses the same separation parameters as the VC-600 with an integrated enclosed housing. Its dedicated product page is still in development, so no inactive link is published here.

How Automatic Sludge Discharge Works
The automatic system separates and removes solids as a controlled operating cycle. Exact timing and control logic are set for the actual contaminant and solids loading; they are not copied from one application to another.
Separate Solids
Denser fines and sludge move toward the bowl wall while separated fluid follows the outlet path back to the sump.
Initiate Discharge
The control system starts the configured discharge sequence after the selected operating condition or interval is reached.
Remove and Resume
The scraper and discharge path remove collected solids so the system can continue its next separation cycle.

The tubular bowl creates the centrifugal field used for solid-liquid separation. The scraper and discharge path manage the solids retained in the collection area. These parts have different jobs: the bowl provides separation performance, while the discharge mechanism controls how accumulated material leaves the machine.
Automatic discharge reduces routine manual bowl cleaning, but it does not remove the need for inspection. Wear condition, seals, bearing condition, scraper clearance, discharge-valve movement and sludge outlet cleanliness remain part of preventive maintenance.
Application-specific setupA sticky sludge, dry metallic fines and soft phosphate coating residue do not behave the same way. Discharge timing and inspection frequency must match the real material.
Maintenance & Spare Parts →04 · Operating fit
When Automatic Discharge Is the Right Choice
Automatic discharge is mainly a production-continuity and labour decision. It is usually considered when solids are generated repeatedly, the process runs across multiple shifts or stopping for manual cleaning would disturb the line.
Repeated Solids Loading
Machining, cold forming, grinding, wire drawing and rolling operations may introduce solids throughout the shift rather than in one short batch.
Central or Shared Sumps
A higher-flow model can support circulation from several machines when the sump, pump and return routing are engineered as one system.
Limited Cleaning Windows
Controlled sludge discharge reduces the need to open and clean a collection bowl at frequent production intervals.
Automatic does not mean maintenance-free
Operators still inspect the discharge path, scraper, seals and bearings. Process settings must be checked when the contaminant or production rate changes.
When manual discharge may be better
Batch use, low solids loading, a dedicated single machine or a predictable cleaning window may justify a simpler manual-discharge centrifuge with lower system complexity.

Automatic Sludge Discharge Centrifuge Models
The five automatic configurations cover different combinations of separation force, rated flow, solids capacity and enclosure. The table supports initial screening; final selection requires the fluid and contamination data listed at the bottom of this page.
| Model | Flow Rate | Speed | G-Force | Solids Capacity | Selection Direction | |
|---|---|---|---|---|---|---|
| VC-600 | 60 L/min | 8,000 rpm | 6,500 G | 2 L | Highest G-force; fine dense solids | View Model → |
| VC-600E | 60 L/min | 8,000 rpm | 6,500 G | 2 L | VC-600 performance; enclosed housing | Page in development |
| VC-800 | 80 L/min | 4,500 rpm | 2,800 G | 3.2 L | Mid-range flow selection | View Model → |
| VC-1500 | 150 L/min | 3,000 rpm | 1,860 G | 8 L | Multiple machines; central sump | View Model → |
| VC-2000 | 200 L/min | 3,000 rpm | 1,700 G | 20 L | High solids loading; largest capacity | View Model → |
Rated flow is not a guaranteed separation result. Viscosity, temperature, particle density, particle size, sump volume, piping and pump duty affect actual performance. The VC-600E dimensions and weight differ from the VC-600 because of its enclosed housing, although its main separation parameters are the same.

Applications with Continuous Solids Generation
Cold Forming
Phosphate coating residue and iron fines can build continuously in cold heading oil. Automatic discharge reduces repeated manual solids removal.
View Application →CNC & Grinding
Fine chips, swarf and grinding contamination may circulate through dedicated machines or a shared sump across multiple shifts.
Wire & Cable
Wire drawing lubricant and drawing emulsion can carry aluminium fines, copper fines and other dense metallic contamination.
Tube & Rolling Mill
Mill scale and metallic solids can require repeated separation where a manual cleaning interval would be disruptive.
A production installation may also require a circulation pump, coarse screen, buffer or central sump, controls and safe service clearance. The centrifuge should be integrated as one treatment stage within the complete fluid circuit.
Send the operating temperature, fluid viscosity, contaminant description, machine count, sump volume and required flow before model selection. A fluid sample or site video can clarify difficult sludge behaviour.

The visible output of the automatic cycle is the discharged solids stream. Its moisture, texture and volume depend on the fluid, contaminant, process temperature, flow and control settings. One photograph cannot represent every application.
Commissioning should establish a baseline for solids volume, discharge interval, sump-cleaning frequency, fluid-change interval and any disposable filter media previously used. Compare the same measures after the system reaches stable operation.

We do not apply a universal savings figure. Disposal requirements also depend on the retained fluid, contaminant composition and local environmental rules.
