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. Published diesel capacity at 40°C and 13 cSt is 14,100 L/h (62.08 US GPM, derived), 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. Published MAB 209 throughput is 6,300–7,400 L/h (27.74–32.58 US GPM, derived) on R&O lube oil at 80–90°C and 13,700 L/h (60.32 US GPM, derived) on steam turbine oil at 60–70°C.
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. Published capacity is 14,100 L/h (62.08 US GPM, derived) on diesel at 40°C and 13 cSt and 18,300 L/h (80.57 US GPM, derived) on gas oil at 40°C.
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?
Published MAB 209 capacities are 14,100 L/h diesel at 40°C and 13 cSt (62.08 US GPM, derived), 18,300 L/h gas oil at 40°C (80.57 US GPM, derived), 6,300–7,400 L/h R&O lube oil at 80–90°C (27.74–32.58 US GPM, derived), and 13,700 L/h steam turbine oil at 60–70°C (60.32 US GPM, derived). The 21,000 L/h (92.46 US GPM, derived) rated reference has no source fluid specified.
What turbine or system size is the DMB-062 suited for?
At the published R&O lube-oil range of 6,300–7,400 L/h at 80–90°C (27.74–32.58 US GPM, derived), 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, large marine lube systems, centralized lube oil purification for large industrial complexes, and offshore facilities requiring maximum throughput in a manual-clean design. Published diesel capacity at 40°C and 13 cSt is 14,100 L/h (62.08 US GPM, derived); gas-oil capacity at 40°C is 18,300 L/h (80.57 US GPM, derived).
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 base machine has a published diesel capacity at 40°C and 13 cSt of 14,100 L/h (62.08 US GPM, derived). The DMPX-070 is a self-cleaning commercial class with more than one Alfa Laval base machine, so its capacity must be stated for the exact base machine and fluid. Choose self-cleaning for waste oil, HFO, or crude oil processing where continuous automated desludging is essential.
