Frequently Asked Questions
What is the rated capacity of the Alfa Laval NX 418 decanter centrifuge?
The Alfa Laval NX 418 B31-G two-phase decanter centrifuge has a rated capacity of 110 GPM on water sludge thickening. The three-phase UVNX 418 variant has a rated capacity of 70 GPM on fish stickwater and fishmeal separation.
What is the difference between the NX 418 and UVNX 418 decanter centrifuges?
The NX 418 is a two-phase decanter centrifuge for liquid-solid separation such as sludge thickening and dewatering. The UVNX 418 is a three-phase decanter (tricanter) for liquid-liquid-solid separation such as fish oil, olive oil, and animal fat rendering. Learn more about the difference between decanter and disc centrifuges.
What applications is the Alfa Laval NX-418 decanter used for?
The NX-418 decanter is used for waste oil de-sludging, crude oil tank bottom sludge recovery, municipal wastewater sludge thickening, industrial paint sludge handling, pyrolysis sludge separation, and liquid humus fertilizer processing.
Does Dolphin Centrifuge supply reconditioned NX-418 decanter centrifuges?
Yes. Dolphin Centrifuge supplies reconditioned Alfa Laval NX-418 decanter centrifuges — fully disassembled, inspected, rebuilt to original specifications, and tested before delivery. Contact us at (248) 522-2573 for current availability and pricing.
What G-force does the Alfa Laval NX-418 generate?
The Alfa Laval NX-418 decanter generates 3,150 RCF (G-force) at its rated bowl speed of 4,000 RPM. This centrifugal force enables effective two-phase solid-liquid separation for applications including sludge thickening, wastewater dewatering, and oil desludging. The UVNX-418 operates at the same bowl speed and G-force.
