Alfa Laval AFPX 517 Separator

Alfa Laval AFPX separator centrifuges were specially designed for extremely demanding separation jobs. Key features of the AFPX 517 centrifuge are its ability to handle high flow rates, high solids content and high-temperature processing. These functions make it the ideal choice to handle the tough conditions encountered in the animal and fish processing industries. In addition, the AFPX 517 centrifuge combines a high G-force, high sludge capabilities and automated operation.

Product Description


The AFPX 517 was designed to discharge solids intermittently, while at the same time separating two intermixed and mutually insoluble liquid phases of different densities. The centrifuge comes in a series of optimized executions that are suitable for a considerable number of duties, including separating fish press water, stick water and extracts. Other applications include the purification of fish oil and liver oil, animal fat, peel oil, and similar products.


The actual throughputs depend on variables such as the amount and type of solids, the temperature, viscosity and degree of separation required. The following figures indicate
the rate of performance, although no guarantees are given. Alfa Laval representatives will be pleased to provide you with further information.

Separation – fish press water 25.000–30.000 l/h (110–130 US gpm)
Purification – fish oil 14.000–18.000 l/h (60–80 US gpm)
Purification – animal fat 6.000–8.000 l/h (25–35 US gpm)

Standard design

The machine consists of a frame that has a horizontal drive shaft with clutch and brake, worm gear, lubricating oil bath and vertical bowl spindle in the lower part. The bowl is
mounted on top of the spindle, inside the space formed by the upper part of the frame, the ring solids cover, the collecting cover, and the frame hood. The feed and liquid discharge system, including the paring disc pump for the heavy phase, also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solids-ejecting disc type with a hydraulic operating system for “shooting” (for automatic or manual operation). The electric motor is either of the controlled torque type or made for variable frequency drive. The VFD motor is provided with a protecting cap.

Basic Equipment
