The DE-1000 centrifuges are available in variable frequency drive (VFD), gearbox drive (GBD) and full hydraulic drive (FHD). All three machines utilise a stainless steel bowl and hardened conveyor tiles to ensure reliability and long life and are suitable for Class I, Divsion 1, Group C and D areas.
DE-1000 variable frequency drive (VFD)
The VFD centrifuge offers maximum flexibility in system control and ability to handle a wide range of feed slurries. An environmentally hardened PLC monitors and controls the bowl and conveyor drive motors, as well as the feed pump, and offers both local and remote operation.
Control screens and current system status information are displayed on the operator panel. Electronic load sensing and feed pump control automatically optimise feed rate, and machine efficiency. Bowl speed is variable up to 4000 RPM for an internal acceleration of more than 3000 G’s, and conveyor speed is variable from 1 to 100 RPM.
DE-1000 full hydraulic drive (FHD)
Operating at bowl speeds up to 3400 RPM to produce internal centrifugal acceleration exceeding 2300 G’s, the FHD centrifuge can process 20 lb/gal weighted slurry. A self-contained hydraulic system drives the bowl and differential conveyor hydraulic motors. Conveyor differential speeds are variable from three to 90 RPM. Continuous monitoring of system hydraulic pressure is used for automatic conveyor boost and protects the machine from overloads.
DE-1000 gear box drive GBD)
The GBD centrifuge operates at bowl speeds up to 4000 RPM. A 50 HP electric motor drives the bowl and gearbox through a fluid coupling, belt and pulley arrangement. Alternative bowl speeds are achieved by increasing or decreasing the motor pulley diameter. A mechanical clutch protects the gearbox and motor in case of excessive torque. Motor starters are installed in an explosion-proof enclosure within easy reach of the operator.
