DESILTER
The Hydrocyclone desilter comes in two designs, which are:
- The Derrick Inline Desilters
- The Derrick Round Desilters
Derrick's polyurethane hydrocyclone offers operators a high tech 4" (50 GPM at 75 ft. head) cone while providing contractors an economical replacement for less efficient older equipment. The 1 5/8" circular ramp feed is tangentially blended into the cone entry as a 1 1/4" high by 5/8" wide rectangle. This rectangular ramp entry minimizes turbulence in the upper portion of the cone allowing the solids to move to the wall of the hydrocyclone quickly.
An extra long vortex finder prevents oversized solids from short-circuiting and exiting in the cone overflow before they can be pushed to the wall of the cone at the feed. These high performance features coupled with Derrick's uni-body construction and interchangeable threaded bottom provide customers with the best 4" balanced oil field hydrocyclone for today's toughest drilling projects.
Derrick's 4" desilter cones efficiently remove drilled solids as fine as 15 microns from drilling mud. When combined with our full line of solids control equipment, your drilling operation will have the best chance of removing detrimental drilled solids on the first circulation. Derrick hydrocyclones are manufactured using a specially formulated EU polyurethane which has excellent resistance to heat and abrasion. Derrick hydrocyclones are economical and lightweight.
Service and replacement of the bottom cone section is made quick and easy by A.N.S.I. buttress threaded bottom sections. The apex is available in two styles: tri-nut or snap-on. Derrick's 4" desilter cones are available with ceramic inserts for extreme duty.
Derrick's unique uni-body construction eliminates excess parts and seams where excessive wear begins. The Derrick 4" desilter cone is designed with metal reinforced grooved connections on the feed and overflow fittings allowing it to fit most existing desilter manifolds.
