AI Summary: Dolphin Centrifuge supplies the DMB-062 — Dolphin's highest-capacity manual-clean disc stack centrifuge clarifier. The DMB-062 processes approximately 62 GPM of diesel-viscosity fluid (92 GPM rated on water). Applications include major turbine lube oil purification (30,000+ HP systems), bulk diesel and gas oil polishing at 62–81 GPM, large marine engine lube systems, and centralized lube oil purification for large industrial complexes. Based in Warren, Michigan, Dolphin Centrifuge has over 40 years of experience in centrifugal separation.

The Case for High-Capacity Manual-Clean
For applications with clean, low-solids fluid — such as turbine lube oil purification or clean diesel polishing — a manual-clean centrifuge at high throughput often provides better economics than a self-cleaning unit. The DMB-062 delivers 62 GPM diesel throughput without the complexity, control system cost, and maintenance overhead of hydraulic self-cleaning mechanisms.
In large turbine lube oil applications, fluid cleanliness is usually high (low particulate loading), and cleaning intervals are long — measured in weeks or months rather than days. A single DMB-062 on a planned cleaning schedule outperforms multiple smaller self-cleaning units from both cost and simplicity perspectives. Dolphin Centrifuge can help you calculate the optimal cleaning interval based on your fluid analysis.

Key Applications
Major Power Generation Turbines
Power station steam turbines and gas turbines above 30,000 HP with large lube oil reservoirs. The DMB-062 provides continuous bypass purification at 33–60 GPM on turbine oil, maintaining ISO cleanliness targets across very large oil reservoirs that smaller units cannot service efficiently.
Lube Oil Centrifuge Details →Bulk Diesel & Gas Oil Polishing
Large fuel depots, tank farms, and bulk storage terminals requiring high-throughput diesel and gas oil polishing. The DMB-062 processes 62–81 GPM continuously, maintaining fuel quality across large storage volumes and keeping water and particulates at acceptable levels for downstream equipment.
Diesel Centrifuge Details →Large Marine Lube Oil Systems
Large marine vessels with multiple propulsion turbines, main engine lube systems, and auxiliary machinery lube oil requiring centralized purification. The DMB-062 handles marine application conditions including variable pitch, shock loading, and the need for robust, reliable design.
Centralized Industrial Lube Systems
Large industrial complexes, refineries, and chemical plants with centralized lubrication systems serving multiple large machines from a common reservoir. The DMB-062 handles the high throughput required for centralized purification of very large shared lube oil inventories.
Frequently Asked Questions
What is the throughput of the DMB-062?
The DMB-062 processes ~62 GPM of diesel, ~81 GPM of gas oil at 40°C, ~33 GPM of lube oil (R&O), and ~60 GPM of steam turbine oil. Rated at 92 GPM on water-viscosity fluid — Dolphin’s highest-capacity manual-clean model.
What turbine or system size is the DMB-062 suited for?
At 33 GPM on lube oil (R&O), the DMB-062 suits major turbines above 30,000 HP, large marine turbine installations, centralized lube oil systems for multiple large turbines, and large petrochemical compressor trains with reservoirs of 15,000–50,000+ gallons.
What applications is the DMB-062 best suited for?
Major turbine lube oil (30,000+ HP), bulk diesel and gas oil polishing at 62–81 GPM, large marine lube systems, centralized lube oil purification for large industrial complexes, and offshore facilities requiring maximum throughput in a manual-clean design.
Why choose manual-clean DMB-062 over a self-cleaning centrifuge?
For clean turbine lube oil with very low solids loading, the DMB-062 provides lower capital cost, no self-cleaning control complexity, and simpler maintenance than a self-cleaning unit. In large turbine systems, cleaning intervals of weeks or months make manual cleaning economically attractive. Contact us to calculate your specific cleaning interval.
How does the DMB-062 compare to the DMPX-070?
The DMB-062 (62 GPM diesel, manual-clean) and DMPX-070 (59–72 GPM diesel, self-cleaning) have similar diesel throughput. The DMB-062 is lower cost and simpler for clean turbine lube oil with long cleaning intervals. The DMPX-070 is better for waste oil, HFO, or crude oil processing where continuous automated desludging is essential.
