Coolant Centrifuge for Cleaner Fluid and Stable Production
Remove suspended metal fines, swarf and sludge without disposable filter media in the centrifugal separation stage.
Working mainly with neat oil?Oil viscosity, temperature and solids behaviour require a separate selection route. Use the Centrifugal Oil Cleaner guide for oil-based applications.

02 · Start with the contamination
What Is Circulating Through Your Coolant?
Machining, grinding, rolling and forming processes continuously introduce solids into the fluid circuit. Large chips may settle or be caught by a coarse screen, but fine metallic particles remain suspended and return through pumps, valves and nozzles.
As these particles recirculate, they can settle in low-flow zones, restrict small passages and carry abrasive contamination back to the cutting area. The practical target is therefore not simply clearer-looking fluid. It is a more stable fluid circuit with less repeated exposure to dense, separable solids.
Chips and Swarf
Machining debris that requires coarse protection before fine centrifugal separation.
Sump Deposits
Accumulated solids in low-flow areas increase cleaning work and fluid loss.
A coolant centrifuge targets separable suspended solids. It does not remove dissolved salts, correct coolant chemistry or separate every form of tramp oil; those conditions may require another treatment stage.
03 · Solid-liquid separation
How a Coolant Centrifuge Works
Contaminated fluid enters a rotating tubular bowl. Centrifugal force moves denser solids outward while separated fluid follows the designed outlet path and returns to the sump.

Performance depends on G-force, residence time, flow rate, viscosity, particle density and particle size. Higher flow is not automatically better when the target is very fine solids.
04 · Choose the discharge method
Automatic or Manual Sludge Discharge?
The discharge method is a labour and process decision, not simply a performance ranking. Selection should reflect how quickly solids accumulate, how often operators can inspect the bowl, whether the line can pause and how much variation occurs between shifts. A well-sized manual unit may suit an intermittent process, while continuous production usually benefits from controlled automatic discharge.
Automatic Sludge Discharge
Designed for repeated solids generation, multiple shifts and applications where routine manual bowl cleaning would interrupt production.
- Controlled discharge cycle
- Lower routine operator intervention
- VC-600 / 800 / 1500 / 2000
Manual Discharge
Suitable for batch cleaning, dedicated machines or lower solids loading where a planned manual cleaning interval is acceptable.
- Lower initial equipment complexity
- Operator removes collected solids
- VC-30 series
05 · Compare models
VC Coolant Centrifuge Range
Compare flow, G-force and solids capacity together. The largest flow number is not automatically the best choice for fine solids. Begin with the required sump turnover, then check whether the available residence time and centrifugal force match the contaminant. Solids capacity matters when loading is heavy because it determines how frequently collected material must be discharged.
| Model | Max. Rated Flow | Max. G-Force | Solids Capacity | Selection Direction | |
|---|---|---|---|---|---|
| VC-600 | 60 L/min | 6,500 G | 2 L | Highest G-force; fine dense solids | View Model → |
| VC-800 | 80 L/min | 2,800 G | 3.2 L | Mid-range flow | View Model → |
| VC-1500 | 150 L/min | 1,860 G | 8 L | Multiple machines; central sump | View Model → |
| VC-2000 | 200 L/min | 1,700 G | 20 L | High solids loading | View Model → |
Rated flow is not a universal process guarantee. Final sizing considers viscosity, temperature, contaminant density, required turnover, pipe routing and pump duty.

Detailed page in developmentMultiple-machine installations may require a central sump, circulation pump, coarse protection and controls. The centrifuge is one treatment stage within the complete fluid circuit.
Application review should also consider fluid compatibility, operating temperature, particle density and the volume of solids generated during peak production. Samples or site data help distinguish a separation problem from a chemistry-control problem and prevent selection by flow rate alone.

Measure What Changes After Separation
The first visible output is the separated solids stream: metal sludge is removed from circulation instead of remaining in the sump. The operating benefit comes from preventing the same particles from returning through the production process.

Results must be tied to a real baseline. Record media use, maintenance intervals, coolant condition and solids volume before installation, then compare the same measures after commissioning. We do not apply one savings number to every plant.
