Overview

High-speed, cost-effective centrifuge

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% 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.

Variable speed main drive

The 414 centrifuge has a 14-in diameter and 34-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.

Tungsten carbide discharge ports and hardfaced conveyor flights

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.
