Recently, KES Separation has shipped a refurbished Swaco518 centrifuge to Nigeria after completing comprehensive refurbishment and strict inspection procedures. This equipment is tailored for oilfield solids control, aiming to solve local drilling fluid treatment challenges and support the stable operation of oil drilling projects.
The refurbished Swaco518 centrifuge has undergone rigorous maintenance on core components to ensure reliable performance. KES Separation’s technical team disassembled and cleaned key parts including the stainless steel bowl and scroll, repaired worn tungsten carbide scroll points, and conducted precision dynamic balance tests to guarantee smooth operation at high speeds. The unit was also sandblasted and repainted with corrosion-resistant paint, enabling it to withstand harsh outdoor oilfield conditions in Nigeria. Additionally, the electrical control system and gearbox were fully inspected and maintained to ensure stable functionality.
The refurbished Swaco 518 centrifuge maintains excellent performance parameters. It operates at speeds ranging from 1,900 to 3,250 rpm, generating centrifugal force up to 2,100G for efficient solids separation. With a 14-inch diameter bowl, the unit delivers stable processing capacity, perfectly matching the intensity of local oil drilling operations. Nigeria is a key oilfield market in Africa, with strong demand for reliable solids control equipment.
Except for the refurbished centrifuge, we also have our own brand centrifuge – KESS. We have VFD and fixed speed centrifuge from 9in to 22in bowl diameter. This Swaco518 is equal to KSLW363, same with bowl diameter: 14in. Comparison of main Technical Parameters (14in Fixed Speed Centrifuge) between KSLW363 and Swaco518 as below:

The core purpose of centrifuge is to efficiently separate solids from drilling fluids in oilfield operations. In actual application, the centrifuge works with other solids control equipment to remove fine silts and solids from drilling mud. It recovers valuable drilling fluids for reuse, significantly reducing the costs of makeup fluids and waste disposal. The separated solids can then be further treated in compliance with environmental standards, meeting Nigeria’s growing environmental protection requirements for drilling waste.
KES Separation offers not just the centrifuge, but a bespoken turn-key solution for the entire solids control and drilling waste management loop.
