Centrifuges Offerings

RHE-USE

Two-stage centrifuge system

Remove low-gravity solids and produce clean fluid for reuse in drilling systems.

414 CENTRIFUGE

Barite-recovery decanting centrifuge

Achieve high performance at low operating costs for both oilfield and industrial applications.

CD-500 HV

High-volume, high-speed precision-balanced centrifuge

Simplify solids control with a rotating stainless steel bowl and a single-lead spiral-screw conveyor inside that rotates at a lower rpm.

518 HV

High-volume, high-speed decanting centrifuge

Quickly and effectively dry solids to significantly reduce the costs of makeup fluids and disposal.

Case Study California Boring Reduces Waste by 32% Using Enhanced Fluid Recycling

Conventional mud recycling system failed to remove fine solids and reduce waste disposal

Product Sheet Centrifuge Packages

Our comprehensive portfolio of high-volume and variable speed centrifuges process drilling fluids to the highest possible environmental and performance standards.

Product Sheet 518 HV High-Volume, High-Speed Decanting Centrifuge

Generate centrifugal forces up to 2,100 Gs.

Product Sheet 414 CENTRIFUGE Barite-Recovery Decanting Centrifuge

Recover 95% of barite and return it to the active system while rejecting finer, low-gravity solids.

Product Sheet CD-500 HV High-Volume, High-Speed Precision-Balanced Centrifuge

Hydraulic centrifuge for low-gravity solids separation and barite recovery.

Case Study 518 HV CENTRIFUGE Replaces the Operation of Two Standard 518 CENTRIFUGES

Low-gravity solids have represented a challenge in the Llanos Orientales basin because of highly reactive clays present in the lithology, resulting in increased well fluid costs due to dilution requirements.
