US GPM values are derived from the published L/h figures using 1 US GPM = 227.124707 L/h and rounded to two decimal places. See the authoritative technical-data registry and methodology for source basis and machine-readable records.

DMB-007S - Stainless Steel Variant

The DMB-007S is the stainless steel construction variant of the DMB-007, featuring 316L stainless steel wetted-part construction throughout the bowl assembly. It delivers the same throughput and operating speed as the DMB-007 in a food-grade compatible configuration. The DMB-007S is used for:

  • Edible oil clarification (vegetable oil, olive oil, sunflower oil)
  • Food-grade lubricant purification
  • Pharmaceutical oil clarification
  • Applications requiring stainless steel for chemical compatibility
  • Wash water clarification in food processing environments

Diesel & Gas Oil Polishing

Generator sets and standby power systems requiring continuous fuel polishing. Published throughput is 1,500 L/h (6.60 US GPM, derived) on diesel at 40°C and 13 cSt and 1,950 L/h (8.59 US GPM, derived) on gas oil at 40°C.

Diesel Centrifuge Details →

Food-Grade Oil (DMB-007S)

Edible oil clarification, food-grade lubricant purification, and pharmaceutical oil processing. The DMB-007S stainless construction meets food-grade contact material requirements and is compatible with CIP (clean-in-place) procedures using caustic and acidic cleaning agents.

Food Grade Centrifuge Details →

Quench & Process Oil

Heat treatment quench oil, metalworking oil, and similar industrial fluids requiring periodic clarification to remove soot, scale, and water accumulation. Throughput for these fluids is application-specific.

Frequently Asked Questions

What is the throughput of the DMB-007?

Published MAB 104 capacities are 1,500 L/h diesel at 40°C and 13 cSt (6.60 US GPM, derived), 1,950 L/h gas oil at 40°C (8.59 US GPM, derived), 800 L/h engine lubricating oil at 80–90°C (3.52 US GPM, derived), and 1,400 L/h steam turbine oil at 60–70°C (6.16 US GPM, derived). The 2,200 L/h (9.69 US GPM, derived) rated reference has no source fluid specified.

What is the DMB-007S stainless steel variant?

The DMB-007S features 316L stainless steel bowl construction for food-grade oil, pharmaceutical, or corrosive fluid applications. Same throughput and speed as the DMB-007. Used when carbon steel is not suitable for the application.

What applications is the DMB-007 best suited for?

Turbine lube oil (1,000–3,000 HP systems), diesel polishing on mid-size generators, hydraulic oil purification, and quench oil clarification. Ideal when solids content is low and periodic manual cleaning is acceptable.

When should I choose the DMB-007 over the DMB-004 or DMB-013?

Published diesel capacity at 40°C and 13 cSt is 1,500 L/h (6.60 US GPM, derived), above the DMB-004 at 900 L/h (3.96 US GPM, derived) under the same conditions and below the DMB-013 at 2,900 L/h (12.77 US GPM, derived) under the same conditions. Published engine-lubricating-oil capacity at 80–90°C is 800 L/h (3.52 US GPM, derived).

Can the DMB-007 handle food-grade oil applications?

Yes, with the DMB-007S stainless variant. The DMB-007S features 316L stainless steel bowl construction suitable for edible oil clarification, food-grade lubricant purification, and pharmaceutical oil processing. The carbon steel DMB-007 is for industrial petroleum applications. Contact us to specify the right variant.
