AI Summary: Dolphin Centrifuge supplies the DMB-028 — a high-capacity manual-clean disc stack centrifuge clarifier. Operating at approximately 8,700 RPM with a 7.5 HP motor, the DMB-028 processes approximately 28 GPM of diesel-viscosity fluid (42 GPM rated on water). Suited for large turbine lube oil purification (10,000–25,000 HP), high-volume diesel and gas oil polishing, and large industrial hydraulic oil maintenance. Based in Warren, Michigan, Dolphin Centrifuge has over 40 years of experience in centrifugal separation.

Key Applications
Large Turbine Lube Oil Purification
Steam and gas turbine generators in the 10,000–25,000 HP range, and large industrial turbine-driven equipment. At 15 GPM on R&O lube oil, the DMB-028 delivers high-throughput bypass purification that keeps large lube oil systems continuously clean between scheduled oil changes.
Lube Oil Centrifuge Details →High-Volume Diesel & Gas Oil Polishing
Large fuel storage depots, refinery off-spec handling, and large generator installations with high daily fuel throughput. The DMB-028 polishes diesel at 28 GPM and gas oil at 37 GPM — handling large-scale fuel quality maintenance economically.
Diesel Centrifuge Details →Industrial Compressor Lube Oil
Large reciprocating compressors, centrifugal compressors, and compressor stations in gas processing and petrochemical facilities. The DMB-028 maintains lube oil cleanliness for compressors with large oil reservoir volumes where continuous high-throughput purification is needed.
Central Lube Oil Systems
Centralized lube oil systems serving multiple pieces of industrial machinery from a common reservoir. The DMB-028’s high throughput makes it effective for large central systems where individual machine purifiers would be impractical.
Frequently Asked Questions
What is the throughput of the DMB-028?
The DMB-028 processes ~28 GPM of diesel, ~37 GPM of gas oil at 40°C, ~15 GPM of lube oil (R&O), and ~27 GPM of steam turbine oil. Rated at 42 GPM on water-viscosity fluid. 7.5 HP, ~8,700 RPM.
What turbine or industrial application is the DMB-028 sized for?
At 15 GPM on lube oil (R&O), the DMB-028 suits large turbines in the 10,000–25,000 HP range, large industrial gearboxes, or centralized lube oil purification for multiple machines. Also effective for large diesel polishing at 28 GPM.
When should I choose DMB-028 over the DMPX-028?
Both deliver ~28 GPM diesel throughput. The DMB-028 (manual-clean) suits clean lube oil and diesel where solids are low and planned cleanings are manageable. The DMPX-028 (self-cleaning) is better for feeds with significant solids or when continuous unattended operation is required.
How does the DMB-028 compare to the DMB-019 and DMB-037?
The DMB-028 (28 GPM diesel) sits between the DMB-019 (19 GPM) and the DMB-037 (37 GPM). At 15 GPM on R&O lube oil, it suits turbines in the 10,000–25,000 HP range. See all models at the disc stack centrifuge overview.
Can the DMB-028 serve a centralized lube oil system?
Yes. At 15 GPM on R&O lube oil, the DMB-028 is well suited for centralized systems serving multiple industrial machines from a common reservoir. Contact Dolphin Centrifuge to size the system for your specific configuration and determine the optimal cleaning schedule.
