Manually-operated Centrifugal Separators

CL-30, CL-50, CL-50K, CL-80, and CL-80K
Nozzle-type models are available for all products. (For nozzle-type models, add an "N" to the end of themodel number.)
Pipes of nozzle-type models are located at the fluid surface level, where the fluid reaches when the rotor
rotates, slightly improving defoaming capability and vibration control quality. For nozzle-type models, add
an "N" to the end of the model number, e.g. CL-30N or CL-50KN.
Principle and mechanism
Slurry, water- or oil-based, is continuously sent from thetank or pit to the rotor, where the slurry is centrifuged. If
particles in the slurry have larger specific gravities than
the working fluid, the centrifugal force presses theparticles onto the interior wall of the rotor. This removes
water or oil from the slurry, separating it into sludge(solid material) and clean fluid. The clean fluid thencontinuously overflows from the center part.

・Manual-type is easier to clean
The rotor of our manually-operated centrifugal separator can be easily removed from the machine body.
The rotor lid can be removed to collect sludge in it.
Our hand-operated centrifugal separator is popular because it is easy-to-use and cost-effective.

Semi-automatic Centrifugal Separators

DL-60M, DL-100M, and DL-150M
Semi-automatic models have an "M" at the end of their model numbers, clearly distinguishing them fromconventional fully-automatic models. For example, DL-**M indicates a semi-automatic model, and DL-**A
indicates an original automatic model.

Principle and mechanism
In the filtering operation, the scraper, which has twoblades at a 180-degree angle, and the rotor rotate at thesame time. The scraper divides the interior of the rotor into
two compartments, significantly improving filtering
efficiency. Slurry is pumped into the rotor, where it isseparated into sludge and clean fluid. The centrifugal forcepresses the sludge onto the interior wall of the rotor,
causing the clean fluid to overflow. The weight of the clean
fluid discharges it from the outlet. After the rotor stops
rotating, the dual-shaft mechanism with the rotor andscraper rotates the box spanner, causing the sludge
accumulated on the interior wall of the rotor to drop
beneath it.
・For semi-automatic models, the upper scraper shaft can be rotated after the rotor stops rotating, causing
the scraper to scrape off the sludge inside the rotor. Since the sludge is discharged from the bottom of therotor, it can be easily collected. A base is required since the sludge is discharged from the bottom.

Fully-automatic Centrifugal Separators

DLG-60, DLG-100, DLG-150, and DLG-400

Principle and mechanism
In the filtering operation, slurry is supplied to therotor from the nozzle at the top of themachine. The slurry is then spun off by the spinningdisk and sent to the rotor. The scraper divides theinterior of the rotor into two compartments,
significantly improving filtering efficiency.
The rotor continuously centrifuges theslurry. If foreign matter in the slurry has larger
specific gravities than the fluid, the centrifugal forcepresses the matter onto the interior wall of the rotor,
removing water or oil from the slurry and separating
it into solid material and clean fluid. The clean fluidis then discharged from the bottom of the rotor andcollected in the clean fluid tank

• The machine height includes a base 600 mm high.

Controlling the movement of the automatic unit, and its advantages•

In the cleaning operation, the rotor stops, and the cylinder pushes out the driving bevel gear, sothat it engages with bevel gears A and B. The driving bevel gear moves bevel gears A and B in
opposite directions. The scraper moves with bevel gear A, and the rotor moves with bevel gear B.
Their movement scrapes off the sludge, enabling continuous operation. In addition, the sequencecontrol copies the cleaning movement of human hands. The rotation angle of the scraper isgradually increased, while continuously changing the direction of the rotation. This movement
completely scrapes off the sludge.

•Continuous spraying of oil mist in the spindle protects thebearings. The automatic unit of this new model has a different
mechanism from those of conventional fully-automatic
models, i.e. CL and DL series. This reduces the burden
imposed on the scraper shaft, as well as eliminating thenecessity of a mechanism for stabilizing the rotor. Thus, thenumber of parts is also reduced. This new model has a much
longer product-life cycle and shorter overall height, further
reducing necessary maintenance.

Data on particle removal with different flow rates• As the chart suggests, the flow rate must be determined according to the filtering precision required.
When precise filtering is required, the flow rate must be reduced, and when precise filtering is not
required, the flow rate can be increased.

• The above chart shows the results of an experiment. The figures may vary depending on the viscosity ofthe slurry, specific gravity of the particles, and other factors. The chart does not guarantee the filtering
precision of our products. The chart should be used only as a guide for selecting and operatingproducts.
