Dolphin Centrifuge supplies parts, repairs, and remanufactured Alfa Laval WHPX 513 self-cleaning disc stack centrifuges rated at 72 GPM on diesel fuel (15 HP, 4,150 RPM). Available as the DMPX-070 turnkey module for diesel, fuel oil, waste oil, and crude oil purification. Warren, Michigan — over 40 years of experience.
WHPX 513 Overview
The Alfa Laval WHPX 513 is a self-cleaning disc stack centrifuge built for the three-phase separation of mixed fluids and sludge. Powered by a 15 HP motor, the WHPX 513 achieves a bowl speed of 4,150 RPM and can process 72 GPM of diesel fuel.
This centrifuge is widely used across marine and industrial applications, from shipboard fuel treatment to refinery slop oil processing. Its large bowl volume and generous sludge space make it particularly suited for high-throughput applications where solids loading is moderate to heavy.
Available in explosion-proof configurations for hazardous area installations, the WHPX 513 is a workhorse centrifuge found in re-refineries, fuel terminals, marine vessels, and industrial waste oil processing facilities worldwide.

Applications
Waste Oil and Crude Oil Applications
The WHPX 513's 3.87-gallon sludge space and 72 GPM capacity make it the preferred choice for waste oil re-refining and crude oil BS&W reduction. Dolphin Centrifuge supplies fully reconditioned WHPX 513 centrifuges with new seals, bearings, and wear components, tested to factory specifications before shipment.
Crude Oil Tank Bottom Separation
The WHPX 513 is effective for crude oil tank bottom processing, separating water and sediment from crude oil sludge recovered from storage tanks. Its large sludge space handles the heavy solids loading typical of tank bottom material.
Oilfield and Marine Applications
The WHPX 513 is widely deployed on offshore platforms and in oilfield tank battery installations for crude oil dehydration. Its self-cleaning design allows uninterrupted continuous operation, critical for 24/7 production environments. Contact our team for sample testing to confirm suitability for your application. For ongoing maintenance, see our centrifuge repair services.

What is the rated capacity of the Alfa Laval WHPX 513? ▼
The WHPX 513 is rated at 72 GPM on diesel fuel (13 cSt viscosity). On lighter fluids throughput can exceed 90+ GPM. On heavier fluids like intermediate fuel oil, throughput is reduced proportionally to viscosity. The WHPX 513 is powered by a 15 HP motor with a 3.87-gallon sludge space.
What is the difference between the WHPX 513 and the FOPX 613? ▼
The WHPX 513 is a three-phase self-cleaning disc centrifuge suited for diesel, waste oil, and intermediate fuel oil. The FOPX 613 is a partial-discharge centrifuge specifically engineered for heavy fuel oil (HFO) processing at 380 cSt viscosity, rated at 30 GPM on bunker fuel. Choose the FOPX 613 when processing heavy bunker fuel with high wax content.
Is the WHPX 513 available in explosion-proof configuration? ▼
Yes. The WHPX 513 is available with explosion-proof (Class 1 Div 1 / ATEX Zone 1) motors and controls for installation in hazardous locations. Dolphin Centrifuge supplies explosion-proof WHPX 513 systems as complete skid packages with explosion-proof controls and wiring. Contact Dolphin Centrifuge for hazardous-area specifications.
What Dolphin system uses the WHPX 513 centrifuge? ▼
The Dolphin DMPX-070 centrifuge module is built around the Alfa Laval WHPX 513 (or equivalent MOPX 213 / MAPX 313 / FOPX 613) centrifuge bowl. The DMPX-070 is a complete turnkey system rated at 59–72 GPM on diesel fuel, with full PLC controls, electric heaters, and piping.
Can Dolphin Centrifuge repair or supply parts for the WHPX 513? ▼
Yes. Dolphin Centrifuge supplies genuine and compatible replacement parts for the WHPX 513, including disc stacks, seals, bearings, and discharge valve components.
