The DMPX-070 is a Dolphin-engineered turnkey module class supplied with a remanufactured Alfa Laval MOPX 213 or WHPX 513 centrifuge. These are distinct base machines with different published capacity records, so every flow value remains attached to its exact machine and fluid. Dolphin is an independent remanufacturer and is not affiliated with Alfa Laval.

Source L/h values are canonical. US GPM is derived as L/h ÷ 227.124707 and rounded to two decimals. HFO values apply only to WHPX 513; none is transferred to MOPX 213. See the technical-data methodology and machine-readable DMPX-070 record.
Installation Requirements
- Electrical
- 460 V / 3-phase standard; 240 V / 3-phase available. Single-phase sites: customer can add a phase converter.
- Operating water
- 50 psig, clean potable filtered water - city water works best, soft water only.
- Compressed air
- 100 psig, ~15 cfm (portable compressor is fine). Primary use: AODD sludge pumps on self-cleaning machines.
- Feed
- Hotter separates better - WVO/thick/emulsified oils ideal ~180°F; HFO 200°F+. Pre-strain dirty feed to under 250 microns. A PLC-controlled feed pump is usually built into the skid; if customer-supplied, use positive-displacement/AODD pumps - avoid centrifugal pumps on emulsion-prone fluids.
- Drain
- Separated sludge via AODD pump, 1 to 1.5 inch outlet. Separated water: 1 to 1.5 inch pressurized, or 3 to 4 inch gravity drain.
- Foundation & environment
- Level concrete pad is usually sufficient; small units available on portable cart skids. Indoor install preferred. Outdoor installs must be in a climate-controlled/heated enclosure to prevent freezing - freezing is a safety hazard.
Key Applications
Power Plant HFO & Fuel Treatment
Large diesel and HFO-fired power plants require continuous fuel purification. On the WHPX 513 base machine, published HFO capacity is 15,200 L/h (66.92 US GPM derived) at 30 cSt and 6,400 L/h (28.18 US GPM derived) at 380 cSt. Viscosity is specified at 50°C; the 380 cSt centrifugation temperature is 98°C. These are not MOPX 213 ratings.
Marine Vessel Fuel & Oil Systems
On large commercial vessels, bulk carriers, tankers, and cruise ships, the DMPX-070 handles main-engine fuel and lube-oil treatment. Published diesel values are 14,400 L/h (63.40 US GPM derived) for MOPX 213 and 16,400 L/h (72.21 US GPM) for WHPX 513. Lube-oil capacity remains tied to the exact oil category and base machine shown in the table.
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 provides a cost-effective alternative. Mid-range applications are served by the DMPX-028, while compact installations use the DMPX-014 or DMPX-010. All DMPX classes use an automatic self-cleaning bowl design, but flow comparisons require the exact base machine, fluid, viscosity, and temperature.

Frequently Asked Questions
What is the throughput of the DMPX-070 centrifuge?
DMPX-070 is not one universal flow rating. Published diesel capacity is 14,400 L/h (63.40 US GPM derived) for MOPX 213 and 16,400 L/h (72.21 US GPM derived) for WHPX 513, both at 40°C and 13 cSt. WHPX 513 separately lists a 24,500 L/h (107.87 US GPM) rated reference whose source fluid is unspecified.
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 Dolphin DMPX-070 module specification calls for a 15 HP motor. Motor power does not establish a universal flow: capacity remains tied to the exact base machine, fluid, viscosity, and temperature. See the technical-data registry for the sourced records.
How does the DMPX-070 compare to the DMPX-042?
Compare exact base machines. Published diesel values are 14,400 L/h (63.40 US GPM) for MOPX 213 and 16,400 L/h (72.21 US GPM) for WHPX 513, versus 7,900–10,700 L/h (34.78–47.11 US GPM) across the four exact DMPX-042 variants. Contact us to size the selected machine for your fluid.
