Note: The pump is divided into the vertical pump and horizontal pump, after treatment, solid particles above 200 mesh and solid content 70%-80%.
The treatment capacity (treatability) varies according to the solid content.

Operational Principle
A strong centrifugal force is used to separate the mixture under high-speed rotation.
The classic static hydrocyclone, for example, uses external pressure to push the feed mixture into the cyclone at a greater speed, because the mixture moves along the tangential direction of the cyclone, which causes the liquid to rotate along the wall of the cylinder. This motion is generally referred to as the outer swirl.
The particles in the external swirl are subjected to centrifugal force. If the density of the particle is greater than the density of the surrounding liquid, it will get more and more centrifugal force. Once the centrifugal force is greater than the liquid resistance caused by the movement, the particles will overcome this resistance and move in the direction of the wall of the device and separate from the surrounding liquid.
The particles near the wall of the device are driven by the liquid above the cyclone and move downward along the wall of the cyclone. The particles near the bottom flow port gather together to form a suspension with high consistency, which is discharged from the bottom flow port.
After separation, the liquid rotates downward, and after entering the cone, the inner diameter of the liquid separator decreases gradually, and the speed of the liquid rotation accelerates.
Because of the uneven distribution of pressure along the radial direction when the eddy current is generated, the smaller the axis is, the closer to the axis it approaches to zero and becomes a low-pressure region or even a vacuum region, which leads to the liquid moving towards the axis direction.
The closer to the axis, the smaller the place is.
When arriving at the axis, it approaches to zero becomes a low-pressure region or even a vacuum region, which causes the liquid to movetoward the axis.
At the same time, due to the large reduction of the bottom flow port of the cyclone separator, the liquid cannot be rapidly discharged from the bottom flow port, and the overflow port in the center of the top cover of the swirl cavity moves part of the liquid toward it because it is in the low-pressure area, thus forming an upward rotational motion and discharging from the overflow port.
