What Say Clients

We installed the Belt Type Oil Skimmer on our CNC WMC cool tanks, and the difference in coolant life is remarkable. It effectively extracts floating oil, which has significantly improved the finish of our components and reduced our overall maintenance time.

Precision Machining Facility

Using these oil skimmers has made our treatment process much more efficient and cost-effective. By removing the oil before it reaches our treatment lines, we’ve lowered the costs associated with chemical processing and sending water to the city plant.

Wastewater Treatment Plant

The centrifugal oil filtration machines have been a game-changer for our grinding machines. We’ve seen an extended oil change period and improved product finish without the need for constant filter element replacements, leading to lifelong savings.

Metal Fabrication & Grinding Shop

The Magnetic Filtration system is incredibly effective at removing ferrous contamination, capturing particles smaller than traditional filters can handle. The stainless steel magnetic filter rods are perfect for our industry grade requirements and have helped us reduce waste by allowing us to recycle the collected ferrous material.

Food Processing Maintenance Team

One of the best features of the belt skimmer is its ability to operate at high liquid temperatures up to 100°C. It handles our mild chemical applications perfectly and was a simple, ‘one-time installation’ that has already started paying for itself.

Electroplating Department

We switched to automated magnetic filters to support our 24/7 high-volume processes. They run continuously without requiring stoppages, and because the contamination is removed as a semi-dry cake, we have minimal fluid loss compared to traditional media filters.

Frequently Asked Questions (FAQ)

Do I need to buy replacement filters?

No, you do not need to buy traditional replacement filters.

Magnetic Filtration: These high-quality systems are designed to replace consumable filters. Ferrous waste is removed as a semi-dry cake, and manual versions require no consumable parts for day-to-day operation.

Centrifugal Filtration: These machines operate without a filter element. Because there is no media to clog or replace, you eliminate ongoing replacement costs.

How fast does the rotor spin?

While the exact RPM (Rotations Per Minute) can vary by specific model size, centrifugal oil filtration typically requires high speeds to generate the force necessary to separate heavy contaminants from the oil. These systems are designed for high-volume, 24/7 automated operation to maintain efficiency without needing to stop for cleaning.

Can it remove water?

The primary function of these systems is to separate oil and solids from water or coolant, rather than removing water from the oil:

Minimal Fluid Loss: The magnetic filtration process is highly efficient, allowing virtually all residue fluid to be recovered while only the contamination is removed.

Oil Skimmers: These are specifically designed to remove floating oil from the surface of water or coolant.

Decanters (Accessory): If you use a decanter with your skimmer, it is designed to return any water that was accidentally removed during the skimming process back to the main tank, ensuring you only collect the waste oil.

How It Works

Working Principle & Schematic

Oil enters the centrifuge under pressure and escapes through tangentially opposite nozzles, producing rotor speeds up to 8000 RPM. The resulting centrifugal force removes dirt, depositing it on the inner wall of the rotor in a dense cake form. Clean oil then drains back to the tank by gravity.

Applications (Where to Use)

Machining: Wire Drawing, Grinding, Honing, Thread Rolling, and Super Finishing.
