  • Centrifuge Bowl — Is a manual cleaning model with the bowl bottom and top made of duplex stainless steel for superior mechanical strength and chemical resistance. The bowl lock-ring is made of special AISI 400-series stainless steel. Internal bowl parts such as the distributor, conical separating discs, feed distributor, and the light phase centripetal discharge pumps are made from AISI 316-stainless steel.
  • Frame and Covers — Manufactured of cast iron then sandblasted, heat-treated and epoxy painted. The frame must be secured to the floor using the supplied vibration absorbers and foundation bolts. The covers are aluminum and bolted to the base frame. The covers position the feeding pipe and the centripetal outlet pumps of the clarified liquid phases.
  • Drive — This spindle is belt driven by an electric motor flanged directly onto the equipment frame and controlled by an inverter. All the rotating shafts are mounted on ball bearings. The top vertical shaft bearing is located inside an appropriate shock-absorber collar, specifically designed to compensate for all radial vibrations.
  • Lubrication — Automatic splash lubrication is provided by an oil bath inside the frame. Appropriate caps allow the filling and emptying of the oil. A sight glass allows for easy inspection and control of the lubricating oil level.
