Introduction
This manual contains directions and information concerning the installation, startup,
shutdown and service of the Swaco 414 Centrifuge. Appropriate sections of this
manual must be read and understood before attempting to install, operate or service
this unit. Failure to do so may cause injury to personnel, damage to the equipment or
reduced performance.
The Swaco 414 Centrifuge is known as a decanting type separator. A decanter is a
centrifugal separator having a horizontal axis of rotation. A process liquid or slurry is
supplied to the rotating bowl where the solids are separated from the liquid phase.
The solids are forced to the inner wall of the bowl while the liquid forms a ring inside
the solids. A screw type conveyor transports the solids toward the tapered end of a
conical bowl. The liquid flows in a spiral path, established by the conveyor flights, to
the discharge ports at the large end of the bowl.
The primary application for the 414 Centrifuge is to recover weight material from
weighted liquid mud. This may be for reclaiming the weight material from excess
mud for lowering the plastic viscosity of a mud system.
