30 Second Summary Takeaway
Alfa Laval centrifuges from Dolphin include manual-clean disc stack centrifuges, self-cleaning disc stack centrifuges, stainless steel centrifuges, decanter centrifuges, and auxiliary systems. Manual-clean models suit low-solids liquid-liquid service, while self-cleaning models automatically discharge separated sludge for higher-throughput operation. Stainless steel models serve chemical, sanitary, food-grade, and biotech applications, and decanters handle high-solids sludge, slurry, wastewater, and process streams.
Dolphin Centrifuge is the independent specialist in Alfa Laval centrifuges: remanufactured machines, turnkey systems, parts, and service, built on 40+ years of Alfa Laval experience. Every machine on this page is inspected, rebuilt, tested, and warrantied at our Warren, Michigan shop, and every system is engineered by Sanjay Prabhu, M.S.M.E., who has spent his career on Alfa Laval separation equipment. Apart from Alfa Laval itself, Dolphin is the reliable source for quality Alfa Laval machines: 150+ centrifuges in stock, plus remanufactured centrifuges, turnkey modules, parts, and service from one place.
Where you see a Dolphin model code, it names a Dolphin-built module: DMB models are turnkey packages around a remanufactured Alfa Laval MAB manual-clean centrifuge, and DMPX models are packages around a remanufactured Alfa Laval self-cleaning disc stack centrifuge such as the MMPX, MOPX, or WHPX. The module and skid are Dolphin engineering; the centrifuge inside is Alfa Laval. The base machine for each model is listed in the selector below. Dolphin is an independent remanufacturer and is not affiliated with Alfa Laval.
Find an Exact Model by Diesel Capacity
These are exact Alfa Laval base-machine application values, not blended Dolphin class ratings. The original L/h value is authoritative; US GPM is calculated as L/h ÷ 227.124707.
Capacity changes with fluid, viscosity, temperature, density difference, and solids loading. DMB and DMPX commercial classes can contain more than one base-machine variant, so select that exact machine before using a capacity. See all 148 condition-qualified records and model mappings.

Alfa Laval Solid Bowl aka Manual Clean Centrifuges
Manual clean disc stack centrifuges use a solids-retaining bowl that holds separated sludge until the unit is stopped for cleaning. Their simpler bowl design eliminates the hydraulic sludge ejection system, which makes them easier to install, maintain, and operate. These machines are well suited for continuous liquid-liquid separation where solids are low or negligible. They are a practical choice for straightforward applications that value simplicity and serviceability.
Alfa Laval Auto-Desludging aka Self-Cleaning Centrifuges
Self-cleaning disc stack centrifuges are built for continuous separation of liquids and suspended solids in demanding industrial service. The bowl opens intermittently to discharge separated sludge automatically, allowing long operating cycles without frequent manual intervention. A hydraulic operating system controls the opening and closing sequence at predetermined intervals. This design is ideal for higher-throughput applications that need efficient, automated solids removal.
Alfa Laval Stainless-Steel Centrifuges
Stainless steel disc stack centrifuges are designed for chemical, sanitary, and food-grade applications where corrosion resistance and clean fluid contact surfaces matter. Their high-speed disc-stack design enables continuous processing while separating fine sediment and multiple fluid phases with excellent efficiency. With wetted parts made from high-grade 316L stainless steel, they are well suited for demanding process streams and hygienic production environments. These centrifuges are commonly used where product quality, material compatibility, and reliable separation are critical.
Alfa Laval Decanter aka Horizontal Bowl Centrifuges
Decanter centrifuges are continuous industrial separators designed to remove solids from liquids using high centrifugal force inside a rotating horizontal bowl. A screw conveyor rotates at a differential speed to move settled solids toward the discharge end while clarified liquid exits separately. This design makes decanters especially effective for high-solids applications such as sludge thickening, dewatering, waste streams, and process slurries. They are a strong fit where continuous operation, rugged solids handling, and dependable throughput are the priority.
