The Alfa Laval range of P2 decanter (solid bowl) centrifuges provides a cost-effective, high-performance solution for solid-liquid separation of erosive and/or corrosive slurries. Highly flexible in design, they can be used in industries such as mineral processing, pulp and paper, coal tar, steel and chemicals as the wetted parts are made of corrosion-resistant materials.
High performance decanter centrifuge
- High recovery of product and valuable raw material in continuous operation
- High capacity on small footprint
- Cost-effective operation – no filter cloth, no vacuum pump
- Low life-cycle cost compared with other technologies
- Low labour cost due to less operator intervention
How it works
Technology / Innovation
Robustly designed, the rotating assembly is supported on a box beam frame with main bearings at both ends. The bowl is driven at the conical end by an electric motor using a V-belt. Wear protection using suitable material of construction is provided on the wear parts.
The bowl, conveyor, casing, inlet tube, outlets and other parts that come into contact with the process media are made of AISI 316 and Duplex stainless steel. Super Duplex stainless steel can be provided on certain sizes.
The P2 decanter centrifuge comes with an Alfa Laval plus control package as standard, pre-installed and factory-tested to make sure you get the most out of your set-up. It also helps minimize costs for installation, commissioning, operation and maintenance.

Supporting sustainability goals
The bowl can be equipped with special power plates or tubes that harness and exploit hydraulic energy to reduce overall power consumption. Some of the discharge velocity from the liquid leaving the unit is captured and re-directed to contribute to bowl rotation. This reduces the velocity of the discharged liquid, which in turn reduces overall power requirements. The unique Alfa Laval direct drive system automatically controls the conveying speed to ensure optimum solids dryness, irrespective of acceptable variations in the feed flow.
