The 4” hydro cyclone incorporates a precise combination of proportion, angles, ratios and materials to optimized separation of solids. The 4” hydro cyclone removes 10 to 74 micron solids from drilling mud. When large solids from 40 to 100 are expected in the drilling fluid, it should first be processed through a desander to remove oversize particles.

For optimum performance, the hydro cyclone requires a steady inlet feed pressure ( feed head) and steady feed rate, Feed pressure maybe produced by gravity-feed system or a centrifugal pump in the drilling mud recycling system. Each 4” hydro cyclone required a normal flow rate of 80 GPM at a 75’ head inlet pressure. To accommodate the high flow rate requirement of drilling industry, up to 20 hydro cyclone can be group together with common feed discharge manifolds in either round or in-line configurations.


The Hydro cyclone body is the main component of 4” hydro cyclone, a cone tip is threaded into the bottom of the body. The soft apex id positioned in the tapered hole inside the triangular nut, which is threaded into the cone tip. Tightening the triangular nut compress the apex, thereby reducing the diameter of its opening.

Loosening the triangular nut release compression, allowing the apex to return iys normal size. By varying the opening of apex the hydro cyclone spray pattem may be adjusted during operation.
