Dolphin Centrifuge supplies parts, repairs, and remanufactured Alfa Laval WSPX 303 TGD self-cleaning 3-phase disc centrifuges rated at 8 GPM. Operating at 9,200 RPM and 8,000+ Gs, it removes sub-micron particles and tramp oil from metalworking coolant in mid-size machining facilities. Warren, Michigan — over 40 years of experience.
WSPX 303 Operation
The Alfa Laval WSPX 303 TGD is a 3-phase disc stack centrifuge designed to separate tramp oil and small particles from machine coolant. The WSPX 303 bowl rotates at 9,200 RPM exerting over 8,000 G-Force, making it ideal for cleaning wash liquids, machining coolants, and de-oiling of water.
At 8 GPM on water-based coolant, the WSPX 303 is well matched to multi-machine coolant circuits serving groups of CNC machining centers, transfer lines, or grinding cells. Its automatic sludge discharge cycle allows continuous unattended operation, extending coolant service life and reducing both disposal frequency and fluid replacement cost.

WSPX 407
25 GPM. Highest capacity for large-scale industrial operations.
What is the rated capacity of the Alfa Laval WSPX 303 centrifuge? ▼
The WSPX 303 TGD is rated at 8 GPM on water-based coolant. It is a self-cleaning 3-phase disc centrifuge suited for central coolant systems serving multiple CNC machines or grinding operations in mid-size machining facilities.
What does a coolant centrifuge remove from metalworking fluid? ▼
A coolant centrifuge removes metal fines (chips, grinding swarf, particles down to 1 micron), tramp oil (hydraulic and machine oils that contaminate coolant), and other dense solid contaminants. Removing these contaminants extends coolant life, reduces biocide consumption, and prevents surface finish degradation on machined parts.
How often does the WSPX 303 need to discharge sludge? ▼
The WSPX 303 discharges accumulated sludge automatically at programmable intervals, typically every 30–120 minutes depending on contamination load. Discharge takes only a few seconds and does not interrupt fluid flow. Higher-contamination applications require more frequent discharge cycles.
What G-force does the WSPX 303 generate? ▼
The WSPX 303 bowl rotates at 9,200 RPM generating over 8,000 G-Force. This extremely high G-force enables separation of sub-micron particles and fine metallic swarf that settle out too slowly for gravity filtration, restoring coolant to a clean, reusable condition.
Can Dolphin Centrifuge supply parts or rebuild the WSPX 303? ▼
Yes. Dolphin Centrifuge supplies replacement parts and complete bowl rebuilds for the WSPX 303. Each rebuilt centrifuge is tested to factory specifications. We also offer repair services for the full WSPX series including the WSPX 207, WSPX 307, and WSPX 407.
