Industrial Decanter Centrifuge Rental Program
Decanter centrifuges are the workhorse of solids-liquid separation. Unlike disc stack separators that handle fine particles and liquid-liquid separation, decanters are designed for high-solids feeds — slurries, sludges, and suspensions where the solid phase can represent 5% to 60% or more of the total volume.
Renting a decanter centrifuge from Dolphin Centrifuge gives you access to fully rebuilt, production-ready equipment without the capital expenditure. Every rental decanter is rebuilt in our Warren, Michigan service facility with new bearings, seals, and hard-facing as needed.
Available Decanter Models
| Model | Bowl Diameter | Throughput | Typical Applications |
|---|---|---|---|
| NX-314 | 14 inches | Up to 30 GPM | Wastewater sludge, oily water, drilling mud |
| NX-418 | 18 inches | Up to 80 GPM | Municipal sludge, industrial wastewater, oil sludge |
| G2-40 | 16 inches | Up to 60 GPM | High-G dewatering, fine solids, chemical sludge |
| CHNX-418 | 18 inches | Up to 80 GPM | Food-grade, chemical, pharmaceutical |
Decanter Rental Applications
Our rental decanters serve a wide range of industries and use cases:
- Wastewater Sludge Dewatering: Reduce sludge volume by 70–90% before disposal, cutting hauling and landfill costs
- Oily Water Treatment: Separate free oil from produced water, bilge water, or wash water for compliant discharge
- Crude Oil Recovery: Recover oil from tank bottoms, pit cleanouts, and drilling waste
- Industrial Process: Clarify process liquids, recover valuable solids, or dewater slurries
- Emergency Response: Rapid deployment for spill cleanup, lagoon closure, or regulatory compliance deadlines
- Pilot Testing: Run your actual feed material through a full-scale decanter to generate reliable design data before purchasing

Need a Disc Stack Separator Instead?
If your application involves liquid-liquid separation, fine solids removal, or oil purification, a disc stack centrifuge may be a better fit. See our disc stack centrifuge rental program for DMPX-series self-cleaning separators.
Not sure which type you need? Our sample testing service can determine the optimal centrifuge type and size for your specific material.
