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

Key Applications
Turbine Lube Oil Purification
Steam and gas turbines in the 1,000–3,000 HP range with lube oil reservoirs of 500–2,000 gallons. The DMB-007 handles bypass purification at 4–6 GPM on turbine oil, removing water ingress and particulates to protect bearings and extend oil life between changes.
Lube Oil Centrifuge Details →Diesel & Gas Oil Polishing
Generator sets and standby power systems requiring continuous fuel polishing at 7–9 GPM. The DMB-007 removes free water and particulates from diesel and gas oil in a compact, economical package suited for space-constrained installations.
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. The DMB-007 handles these polishing applications cost-effectively at 5–7 GPM.
Quench Oil Centrifuge Details →Frequently Asked Questions
What is the throughput of the DMB-007?
The DMB-007 processes ~7 GPM of diesel, ~9 GPM of gas oil at 40°C, ~4 GPM of lube oil (R&O), and ~6 GPM of steam turbine oil. Rated at 10 GPM on water-viscosity fluid.
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?
Choose the DMB-007 when your throughput requirement is 5–9 GPM diesel — above the DMB-004 (4 GPM) but below the DMB-013 (13 GPM). For turbine lube oil, the DMB-007 suits 1,000–3,000 HP systems at 4 GPM R&O throughput.
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.
