Decanter centrifuges can be equipped with either VFD electric drive or hydraulic drive. Choosing the right system depends on your application, feed conditions, site power, and maintenance capability.

VFD Drive Centrifuge

Simple structure, easy electrical control

Lower maintenance cost

Ideal for stable feed, medium solids content, continuous operation

Recommended for conventional drilling mud, mud cleaning, general wastewater

Hydraulic Drive Centrifuge

Better for high-solids, high-viscosity, fluctuating loads

Handles heavy sediment, frequent start-stop, harsh site conditions

More complex system with higher maintenance requirements

Recommended for mineral slurry, oil sludge, heavy slurry, severe applications

Quick Selection Advice

Choose VFD for stable operation, good power supply, and easy maintenance.

Choose Hydraulic for tough materials, load fluctuations, and difficult field conditions.

For overseas projects without severe conditions, VFD is often preferred. If high-viscosity or heavy solids are involved, hydraulic drive should be considered.

Always confirm feed material, solids content, viscosity, power supply, and site environment before final selection.
