Q Series

Our comprehensive dairy range includes the Alfa Laval Q517, a nozzle separator specifically engineered to meet the demands of highly viscous dairy products such as quark and Greek yoghurt. The Q517 offers you a unique solution for greater flexibility, reliability and control over the product quality.


A quark separator specially engineered for viscous products

  • A fit-for-purpose solution carefully designed to provide efficient and reliable separation and high yield
  • A nozzle separator that gives you flow control and process flexibility
  • High preservation of product quality thanks to a gentle inlet and outlet design that reduces drop splitting
  • Easy to clean with discharge function that prevents nozzle clogging for efficient cleaning-in-place (CIP)
  • Maximum reliability thanks to high-grade stainless steel that resists corrosion from chlorides and CIP chemicals

A dependable solution for quark dairy products

The Q517 nozzle separator has been specifically developed to meet the challenges with viscous types of products. Built with our PX discharge function, it ensures gentle handling of products like quark and the thickest yoghurts. It also features high-quality components that contribute to reliable assurance of product safety and quality. Together with our innovations for efficient separation, the Q517 gives you confident assurance of hygienic, dependable and cost-effective separation for your niche product processing.

Features that make the difference

What sets Alfa Laval separators apart is what’s on the inside: a broad scope of unique and patented technologies that, taken together, help dairy customers achieve improved product quality along with superior hygienic confidence. They also make it possible to drastically decrease both water and energy consumption, reducing both operational costs and environmental footprint.


Hermetic Design

Gentle acceleration, powerful efficiency

A unique air-tight bowl that enables improved product quality and drastically reduces power consumption.



Mechanical simplicity for higher efficiency and lower costs

A direct-drive system with fewer rotating parts that minimizes both maintenance and energy costs.



New levels of capacity and hygiene

A radical new disc design that decreases cleaning needs while increasing flow rate by up to 20%.



Double the output per kWh

An innovation to minimize friction, which cuts the separator´s energy consumption and CO2 footprint by up to 70%.



Outstanding solids capacity

Continuous solid discharge ensures an intact and highly concentrated stream for onward processing or as a valuable by-product. This makes it possible to increase separation capacity.

The Separator Innovator

Alfa Laval invented the first disc stack separator over a century ago. Since then, we have led the way by constantly improving and reinventing centrifuge technology. Making it safer, more efficient, and more sustainable. Visit our Separator Innovator knowledge base and discover how we continue to revolutionize separation processes across industries.
