AI Summary: Dolphin Centrifuge supplies the DMB-019 — a manual-clean disc stack centrifuge clarifier rated at 19 GPM on diesel (13 cSt) and 29 GPM water-rated throughput. Operating at 8,700 RPM with a 5 HP motor, the DMB-019 is suited for large turbine lube oil purification (5,000–15,000 HP), high-volume diesel 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 Systems
Turbine generators in the 5,000–15,000 HP range with large lube oil reservoirs. The DMB-019 handles bypass purification at 10–19 GPM on turbine oil, removing water ingress and particulates to maintain ISO cleanliness targets and extend oil drain intervals.
Lube Oil Centrifuge Details →High-Volume Diesel & Gas Oil Polishing
Large standby generators, prime power installations, and diesel fuel storage facilities with large tank volumes. The DMB-019 polishes fuel at 19–25 GPM, maintaining fuel quality and removing water contamination before it reaches engine fuel systems.
Diesel Centrifuge Details →Large Industrial Hydraulic Systems
Heavy industrial presses, rolling mills, die casting machines, and other large hydraulic equipment requiring continuous oil purification. At 10 GPM on hydraulic oil, the DMB-019 maintains system cleanliness across large oil volumes.
Process Oil & Compressor Lube
Large reciprocating and screw compressors, process industry lubrication systems, and industrial gearboxes requiring continuous oil polishing at higher flow rates than smaller DMB models can provide.
Frequently Asked Questions
What is the throughput of the DMB-019?
The DMB-019 processes ~19 GPM of diesel, ~25 GPM of gas oil at 40°C, ~10 GPM of lube oil (R&O), and ~19 GPM of steam turbine oil. Rated at 29 GPM on water-viscosity fluid. Operating at 8,700 RPM, 5 HP.
What turbine size is the DMB-019 suited for?
At 10 GPM on lube oil (R&O), the DMB-019 suits turbines from approximately 5,000–15,000 HP with lube oil reservoirs of 2,000–10,000 gallons. Contact Dolphin Centrifuge for a sizing calculation based on your specific turbine and oil reservoir.
When should I choose DMB-019 over the DMPX-028?
Choose the DMB-019 when solids content is low and periodic planned cleaning is acceptable — primarily for clean turbine lube oil and diesel polishing. The DMPX-028 is better when solids loading is moderate to high, continuous unattended operation is required, or manual cleaning labor costs outweigh the self-cleaning price premium.
How does the DMB-019 compare to the DMB-013 and DMB-028?
The DMB-019 (19 GPM diesel) sits between the DMB-013 (13 GPM) and the DMB-028 (28 GPM). At 10 GPM on lube oil (R&O), it bridges the gap for turbine systems in the 5,000–15,000 HP range. See the full comparison at the disc stack centrifuge overview.
What is the motor size for the DMB-019?
The DMB-019 uses a 5 HP motor at 8,700 RPM, delivering the centrifugal force needed for effective separation of lube oil, diesel, and gas oil across its full rated throughput range. Contact us for full electrical specifications and available power configurations.
