Dolphin Centrifuge supplies parts, repairs, and remanufactured Alfa Laval WSPX 407 TGD 3-phase self-cleaning disc stack centrifuges rated at 25 GPM, spinning at 8,500 RPM with over 7,000 G-Force. Available as the DMPX-042C module for continuous tramp oil and particle removal from machining coolants, wash liquids, and washer fluids. Warren, Michigan — over 40 years of experience.
WSPX 407 Operation
The Alfa Laval WSPX 407 TGD is a 3-phase disc stack centrifuge designed to separate tramp oil and small particles from machine coolant. The centrifuge bowl rotates at 8,500 RPM, exerting over 7,000 G-Force for efficient separation of contaminants from water-based machining coolants and wash liquids.
Rated at 25 GPM, the WSPX 407 is ideal for cleaning wash liquids, water-based machining coolants, and de-oiling of washer fluids in automotive, aerospace, and precision machining facilities. The self-cleaning bowl has 0.87 gallons of sludge space.
Its automatic sludge discharge cycle ejects solids on a programmable timer without stopping fluid flow, making it compatible with 24/7 production schedules. The 10 HP motor drives the bowl at full separation speed continuously. For ongoing maintenance, Dolphin Centrifuge offers full centrifuge repair and rebuild services for the WSPX series.

What is the rated capacity of the Alfa Laval WSPX 407? ▼
The WSPX 407 TGD is rated at 25 GPM. The centrifuge bowl spins at 8,500 RPM generating over 7,000 G-Force, enabling efficient separation of tramp oil and sub-micron metal fines from water-based machining coolants and wash liquids.
What is the DMPX-042C module that Dolphin Centrifuge supplies? ▼
The DMPX-042C is Dolphin Centrifuge's complete coolant centrifuge module built around the Alfa Laval WSPX 407. It includes the centrifuge, controls, pump, and skid — configured for continuous coolant processing at 25 GPM. Dolphin Centrifuge supplies, services, and rebuilds the DMPX-042C for industrial customers across North America.
What applications is the WSPX 407 used for? ▼
The WSPX 407 is a 3-phase separator used for cleaning water-based machining coolants, wash liquids, and de-oiling of washer fluids. Common applications include automotive machining, aerospace part manufacturing, and precision grinding facilities where continuous tramp oil and particle removal is required.
How does the WSPX 407 differ from the WSPX 307? ▼
The WSPX 407 (25 GPM, 8,500 RPM) is the upgraded successor to the WSPX 307 (22 GPM, 8,600 RPM). The WSPX 407 offers slightly higher capacity while maintaining the same compact form factor and all stainless steel wetted surface design suited for corrosive coolant applications.
Can Dolphin Centrifuge supply parts or rebuild the WSPX 407? ▼
Yes. Dolphin Centrifuge supplies genuine and compatible replacement parts for the WSPX 407, including disc stacks, seals, bearings, and discharge valve components. Complete bowl rebuilds and remanufactured WSPX 407 centrifuges are available. Contact us for parts availability and service scheduling.
