Key Applications
Power Plant HFO & Fuel Treatment
Large diesel and HFO-fired power plants require continuous fuel purification to protect injectors and combustion systems. The DMPX-070 processes HFO at up to 59–67 GPM (30 cSt) and 25–28 GPM (380 cSt), handling the full fuel delivery needs of multi-megawatt generation facilities around the clock.
Marine Vessel Fuel & Oil Systems
On large commercial vessels, bulk carriers, tankers, and cruise ships, the DMPX-070 handles main engine HFO purification and lube oil treatment simultaneously. At 29–38 GPM lube oil throughput and up to 72 GPM diesel throughput, it meets the demanding fuel and oil requirements of large-bore marine diesel and gas turbine engines.
Refinery Slop Oil Recovery
Refineries generate significant volumes of slop oil — mixed hydrocarbon streams contaminated with water and sediment. The DMPX-070 recovers this product-quality oil at high throughput, reducing refinery waste, improving yields, and minimizing environmental liability from contaminated oil disposal. See our waste oil centrifuge page for more on oil recovery applications.
Large-Volume Crude Oil BS&W Reduction
For upstream production operations, gathering stations, and crude oil pipelines requiring BS&W (basic sediment and water) reduction ahead of custody transfer or pipeline specification compliance, the DMPX-070 delivers the throughput needed to process high-volume crude streams continuously and without manual intervention.

The DMPX-070 as the Dolphin Series Flagship
The DMPX-070 is the largest model in the Dolphin DMPX range, delivering the highest throughput for the most demanding industrial applications. For applications requiring somewhat lower flow rates, the DMPX-042 (~32–47 GPM) provides a cost-effective alternative. Mid-range applications are served by the DMPX-028 (~20–26 GPM), while compact installations use the DMPX-014 (~13 GPM) or DMPX-010 (~7 GPM). All DMPX models share the same automatic self-cleaning bowl design and continuous three-phase separation capability.

Frequently Asked Questions
What is the throughput of the DMPX-070 centrifuge?
The DMPX-070 processes 59–72 GPM of diesel fuel at actual operating conditions, with a rated capacity of 95–108 GPM under ideal low-viscosity conditions. Lube oil (R&O) throughput is 29–38 GPM and steam turbine oil is 62–70 GPM. HFO 380 cSt is processed at 25–28 GPM.
What is the DMPX-070 used for?
The DMPX-070 is used for large-scale power plant HFO and diesel fuel treatment, marine vessel main engine fuel and lube oil purification, refinery slop oil recovery and crude oil dewatering, and high-volume industrial waste oil reclamation. Its 3.65–3.96-gallon sludge bowl supports continuous operation even with heavily contaminated streams.
How large is the DMPX-070 sludge bowl?
The DMPX-070 features a 3.65–3.96-gallon sludge bowl — the largest in the Dolphin DMPX series. This large bowl capacity reduces ejection frequency and supports continuous operation even with high-solids streams such as crude oil tank bottoms, heavily contaminated waste oil, and high-ash HFO.
What motor power does the DMPX-070 require?
The DMPX-070 is driven by a 30–40 HP motor, reflecting its large bowl size and high-throughput capability. This makes it the most powerful model in the Dolphin DMPX self-cleaning disc stack series, suitable for applications where smaller models would require multiple parallel units.
How does the DMPX-070 compare to the DMPX-042?
The DMPX-070 provides roughly 50–80% more throughput than the DMPX-042 (59–72 GPM vs. 32–47 GPM on diesel) and features a much larger 3.65-gallon bowl vs. 1.64 gallons. The DMPX-070 is the right choice for power plants, large marine vessels, and refineries where the DMPX-042's capacity would require parallel units.
