The M-I SWACO 414 CENTRIFUGE is engineered to deliver high performance at low operating costs for both oilfield and industrial applications. This highly efficient decanting centrifuge recovers 95 percent of barite and returns it to the active system, while rejecting finer, low-gravity solids. The advanced design of the stainless steel bowl and scroll maintains an even layer of conveyed solids for more uniform separation and maximum solids-control efficiency.
The M-I SWACO 414 Centrifuge has 14.0 in. diameter and 34.0 in length (353-mm x 860-mm) with a stainless steel bowl and conveyor assembly. The variable speed main drive is v-belt driven through a torque converter by a 25-hp, explosion-proof, electric motor. The main drive (1,600-3,300 rpm) bowl speeds are easily changed with the variable-step sheave arrangement. The differential or back drive is v-belt driven by a 7.5-hp, explosion-proof, and electric motor. The differential speed of the conveyor can be adjusted from -18 to a maximum of +85 rpm.
The 414 CENTRIFUGE consists of a contour bowl assembly that includes hardfacing protection in the feed zone, tungsten carbide discharge ports and hardfaced conveyor flights. A two-step planetary 3.5-knm gearbox with a 57.1:1 ratio drives the centrifuge. Additional overload protection is provided with a mechanical clutch and safety shutdown devices.
