Filtering cylindrical–conical hydrocyclone
An important characteristic of the filtering hydrocyclone is the absence of filter-cake formation because of the high swirl velocity of the fluid.

1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.
