By Owner and Chief Engineer, Dolphin Centrifuge Last reviewed: August 2026

The Alfa Laval MOPX 209 is a self-cleaning disc stack centrifuge with a 15 HP motor at 5,180 RPM. Its OEM application table lists 7,900 L/h (34.78 US GPM derived) for diesel at 40 °C and 13 cSt. Gas oil and lube oils have separate values and conditions; this machine is one exact base option for the Dolphin DMPX-042 module.

MOPX 209 Total-Discharge Centrifuge

The Alfa Laval MOPX 209 Centrifuge has a 15 HP motor and a bowl speed of 5,180 RPM. It is a self-cleaning, disc stack centrifuge designed for continuous three-phase separation of fuels and mineral oils. The OEM values below apply only to the named fluids and listed conditions; biodiesel, waste oil, and other duties require application-specific sizing.

Dolphin Centrifuge is the independent specialist in Alfa Laval centrifuges. Apart from Alfa Laval itself, Dolphin is the reliable source for quality Alfa Laval machines: remanufactured MOPX 209, WHPX 409, and MAPX 309 centrifuges, turnkey systems, parts, and service, built on 40+ years of Alfa Laval experience and led by Sanjay Prabhu, M.S.M.E. Every machine on this page is a genuine Alfa Laval, stripped, rebuilt, balanced, and tested in Dolphin's Warren, Michigan shop. Dolphin is an independent remanufacturer and is not affiliated with Alfa Laval.

The MOPX 209 ships either as a bare remanufactured centrifuge or inside the Dolphin DMPX-042 module, a Dolphin-engineered turnkey skid featuring a remanufactured Alfa Laval MOPX 209. The module frame, heaters, pump, piping, and PLC controls are Dolphin's engineering; the centrifuge at the heart of it is Alfa Laval.

The Alfa Laval WHPX 409 Centrifuge is a self-cleaning disc-stack centrifuge designed for three-phase separation of diesel and fuel oils. With a 12.5 HP motor and a 7,125 RPM bowl, its OEM application table lists 8,400 L/h (36.98 US GPM derived) for marine diesel. Crude-oil duty requires separate application sizing and does not inherit the diesel value.

Alfa Laval MAPX 309 BGT-14, Full-Discharge, Disc-Stack Centrifuge

The Alfa Laval MAPX 309 Centrifuge is a heavy-duty, self-cleaning disc-stack centrifuge used for mineral-oil and fuel duties. Dolphin's current OEM capacity registry does not include a source record for MAPX 309, so no flow value is published here and no MOPX 209 or WHPX 409 value should be transferred to it.

Frequently Asked Questions

What is the Dolphin equivalent of the Alfa Laval MOPX 209 centrifuge?
The Alfa Laval MOPX 209 is one exact base-machine option for the Dolphin DMPX-042 centrifuge system. Other DMPX-042 variants use MOPX 210, WHPX 409, or WHPX 510 base machines. The DMPX-042 adds a complete system frame, PLC controls, electric heaters, feed pump, and piping; capacity must be quoted for the exact base machine and fluid, not as one blended DMPX-042 rating.
What is the flow rate of the Alfa Laval MOPX 209 centrifuge?
The OEM application table for the exact Alfa Laval MOPX 209 lists 11,800 L/h (51.95 US GPM derived) for gas oil at 40 C; 7,900 L/h (34.78 US GPM derived) for diesel at 40 C and 13 cSt; 4,100 L/h (18.05 US GPM derived) for R&O / engine lube oil at 80–90 C; and 7,700 L/h (33.90 US GPM derived) for steam-turbine lube oil at 60–70 C. Each value is fluid- and condition-specific.
What applications is the Alfa Laval MOPX 209 / DMPX-042 best suited for?
The MOPX 209 / DMPX-042 is a mid-to-large self-cleaning centrifuge option for diesel and gas-oil purification, waste-oil recovery, cutting-oil clarification, lube-oil purification, and qualified crude-oil duties. The exact base machine, fluid properties, temperature, contamination, and separation target must be selected before stating a design flow.
What is the motor horsepower of the Alfa Laval MOPX 209?
The Alfa Laval MOPX 209 centrifuge uses a 15 HP main drive motor. The complete Dolphin DMPX-042 system module typically includes a 15 HP centrifuge motor plus additional pump motor (1–3 HP) and optional electric heaters (up to 60 kW).
Is the Alfa Laval MOPX 209 centrifuge available explosion-proof?
Yes. The Dolphin DMPX-042 (built around the MOPX 209 bowl) is available in Class I Division 2 explosion-proof configuration for hazardous area installations. Contact Dolphin Centrifuge at (248) 522-2573 for explosion-proof options.
