Key Applications
Large Turbine Lube Oil Systems
Turbine generators in the 5,000–15,000 HP range with large lube oil reservoirs. Published MAB 205 throughput is 2,000–2,300 L/h (8.81–10.13 US GPM, derived) on R&O lube oil at 80–90°C and 4,200 L/h (18.49 US GPM, derived) on steam turbine oil at 60–70°C.
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. Published throughput is 4,400 L/h (19.37 US GPM, derived) on diesel at 40°C and 13 cSt and 5,750 L/h (25.32 US GPM, derived) on gas oil at 40°C.
Diesel Centrifuge Details →Large Industrial Hydraulic Systems
Heavy industrial presses, rolling mills, die casting machines, and other large hydraulic equipment requiring continuous oil purification. Hydraulic-oil throughput is application-specific and must be confirmed from viscosity, temperature, and separation duty.
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?
Published MAB 205 capacities are 4,400 L/h diesel at 40°C and 13 cSt (19.37 US GPM, derived), 5,750 L/h gas oil at 40°C (25.32 US GPM, derived), 2,000–2,300 L/h R&O lube oil at 80–90°C (8.81–10.13 US GPM, derived), and 4,200 L/h steam turbine oil at 60–70°C (18.49 US GPM, derived). The 6,500 L/h (28.62 US GPM, derived) rated reference has no source fluid specified. The base machine uses a 5 HP motor.
What turbine size is the DMB-019 suited for?
At the published R&O lube-oil range of 2,000–2,300 L/h at 80–90°C (8.81–10.13 US GPM, derived), 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?
At the same published diesel condition of 40°C and 13 cSt, the DMB-019 base machine is rated at 4,400 L/h (19.37 US GPM, derived), between the DMB-013 at 2,900 L/h (12.77 US GPM, derived) and the DMB-028 at 6,400 L/h (28.18 US GPM, derived). Its published R&O range at 80–90°C is 2,000–2,300 L/h (8.81–10.13 US GPM, derived). 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.
