Used Alfa Laval NX314 Decanter Centrifuge – 14" Stainless Bowl, 88 GPM, Less Than 10 Hours

Manufacturer Information

Alfa Laval

Alfa Laval is a globally recognized manufacturer of separation, heat-transfer, and fluid-handling equipment. Its horizontal decanter centrifuges are used for continuous liquid-solid separation, clarification, dewatering, and solids concentration across wastewater, food and beverage, chemical, pharmaceutical, biotechnology, rendering, and other industrial processes.

The Alfa Laval NX314 uses high-speed centrifugal force and a continuous scroll conveyor to separate solids from liquid in compatible process streams.

Description

Available for sale is a used Alfa Laval Model NX314 horizontal decanter centrifuge, built in 2018, with less than 10 reported operating hours.

The centrifuge features a 14" diameter bowl with stainless steel product-contact surfaces and a maximum bowl speed of approximately 3,250 RPM. Its stated hydraulic capacity is up to 20 cubic meters per hour (approximately 88 GPM), depending on feed characteristics and required separation performance.

For improved wear resistance in abrasive applications, the internal conveyor features tungsten carbide hard-surfaced flights.

The centrifuge is driven by a 15 HP motor with variable-frequency drive (VFD). A planetary gearbox with torque limiter controls the relationship between the bowl and conveyor, while integrated vibration and over-torque protection provide additional equipment safeguards.

The package includes a 25 GPM progressive cavity feed pump for controlled introduction of feed material into the centrifuge. Separated liquid and solids utilize gravity discharge.

A NEMA 4 local control panel is also included, providing a protected operator-control interface suitable for compatible industrial environments.

With less than 10 reported hours, stainless steel contact surfaces, wear-resistant conveyor flights, VFD drive, feed pump, and controls, this NX314 presents an attractive option for facilities requiring continuous liquid-solid separation or dewatering capacity.

Serial Number: 2929895.
