The Derrick round and inline desilters are designed to remove silt-sized (20 to 74 microns) solids from drilling fluids. Derrick’s round desilters are simple to operate and easy to maintain. Optional shutoff valves on each round desilter cone inlet permit individual cone removal and inspection without interrupting operation of the desilter. The Derrick inline desilter is designed for use in areas that cannot accommodate the spatial requirements for the premium round desilter configuration. Both the round and inline desilters are available in a variety of sizes up to 20 cone models. Available cone quantity dependent on machine type.

Derrick’s polyurethane hydrocyclone offers a high volume 4” cone, while providing contractors an economical replacement for less efficient older equipment. Derrick’s unique uni-body construction eliminates excess parts and seams where excessive wear can occur. Derrick’s 4” desilter cones are available with ceramic inserts for extreme service.
