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.
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.
