Key Applications
Very Large Turbine Lube Oil
Large steam turbine generators above 20,000 HP, gas turbine generators, and large turbine-driven compressor trains in petrochemical, power generation, and marine applications. Published MAB 207 throughput on R&O lube oil at 80–90°C is 3,800–4,400 L/h (16.73–19.37 US GPM, derived).
Lube Oil Centrifuge Details →High-Volume Gas Oil Polishing
Large fuel depots, refineries, and bulk storage facilities requiring high-volume fuel polishing. Published capacity is 8,400 L/h (36.98 US GPM, derived) on diesel at 40°C and 13 cSt and 11,300 L/h (49.75 US GPM, derived) on gas oil at 40°C.
Diesel Centrifuge Details →Large Compressor Lube Oil
Gas compression stations, refinery compressor trains, and large industrial compressors with high lube oil volumes. Compressor-lube throughput is application-specific and must be confirmed from viscosity, temperature, and separation duty.
Centralized Industrial Lube Systems
Centralized lube oil systems serving multiple large industrial machines, rolling mills, or large gear trains from a common reservoir. The DMB-037’s high throughput handles centralized purification efficiently without the complexity of self-cleaning controls.
Frequently Asked Questions
What is the throughput of the DMB-037?
Published MAB 207 capacities are 8,400 L/h diesel at 40°C and 13 cSt (36.98 US GPM, derived), 11,300 L/h gas oil at 40°C (49.75 US GPM, derived), 3,800–4,400 L/h R&O lube oil at 80–90°C (16.73–19.37 US GPM, derived), and 8,100 L/h steam turbine oil at 60–70°C (35.66 US GPM, derived). The 12,500 L/h (55.04 US GPM, derived) rated reference has no source fluid specified.
What applications is the DMB-037 best suited for?
Very large turbine lube oil (20,000+ HP systems), high-volume diesel and gas-oil polishing, large compressor lube oil, and centralized purification systems for multiple large machines where self-cleaning is not required. Published diesel capacity at 40°C and 13 cSt is 8,400 L/h (36.98 US GPM, derived); gas-oil capacity at 40°C is 11,300 L/h (49.75 US GPM, derived).
When should I choose DMB-037 versus DMB-062?
At the same published diesel condition of 40°C and 13 cSt, the DMB-037 base machine is rated at 8,400 L/h (36.98 US GPM, derived), while the DMB-062 base machine is rated at 14,100 L/h (62.08 US GPM, derived). Their published R&O ranges at 80–90°C are 3,800–4,400 L/h (16.73–19.37 US GPM, derived) and 6,300–7,400 L/h (27.74–32.58 US GPM, derived), respectively.
How does the DMB-037 compare to the DMPX-042 self-cleaning model?
The DMB-037 base machine has a published diesel capacity at 40°C and 13 cSt of 8,400 L/h (36.98 US GPM, derived). The DMPX-042 is a self-cleaning commercial class with several Alfa Laval base machines, so its capacity must be stated for the exact base machine and fluid. Choose self-cleaning when solids loading is significant or continuous unattended operation is required.
What turbine size is the DMB-037 suited for?
At the published R&O lube-oil range of 3,800–4,400 L/h at 80–90°C (16.73–19.37 US GPM, derived), the DMB-037 suits large turbines above 20,000 HP, gas turbine-driven compressor trains, and large centralized lube oil systems. The DMB-062 range under the same conditions is 6,300–7,400 L/h (27.74–32.58 US GPM, derived).
