Decanter Centrifuge

ESS-1967HD2 Barite Recovery & Dewatering Centrifuge


Whether you are working toward maximizing barite recovery or looking to get the most out of your “zero-discharge” closed-loop system, Elgin’s field proven decanter centrifuges are a perfect choice.  With over 500 centrifuges installed worldwide, the ESS-1967HD2 represents Elgin’s flagship decanter centrifuge.


Power and Performance

Elgin’s ESS-1967HD2 Decanter Centrifuge is fitted with a NEMA premium, continuous duty, energy-efficient, poly-chain driven, 125 hp main drive and a direct-coupled 40 hp back-drive. The 125 hp main drive can operate the centrifuge up to a maximum rotational speed of 3,100 rpm, therefore generating more than 2,500 G’s of force.  Using an inclined motor mount, motor and belt maintenance is made easy by the adjustment of two jack screws.  No additional motor mounts, brackets or tensioning devices are required.   By utilizing a carbon fiber poly-chain, no belt retensioning is required after installation is complete.  The carbon fiber tensile cords are length-stable and can withstand shock loads that frequently lead to belt failure.  More importantly, Elgin’s carbon fiber poly-chain will not require quarterly replacement.


Another significant advantage relative to the use of poly-chains is the lowered energy consumption.  Since the poly-chain operates with a positive tooth/groove engagement, there is no start-up or operational slippage.   The combination of the poly-chain, sheave selection and shaft-to-shaft distances, the 125 hp motor delivers more than 125% of the required power to operate the ESS-1967HD2.


The 40 hp back-drive coupled with an 80:1 planetary gearbox generates an industry-leading speed differential, which ultimately translates into a larger performance window.   This performance window is what grants the ESS-1967HD2 maximum flexibility when managing the solid/liquid cut-point and the moisture content of discharged solids.  Decanter centrifuges with a large gear box, provide a smaller differential range.   This is more than acceptable when dealing with wastewater and industrial applications.  On the other hand, there are a myriad of challenging drilling fluid conditions in which the specific gravity of the materials experienced can vary greatly.  As such, a wide differential range is essential to performance and application flexibility.
