Alfa Laval AB

Valves are used to regulate and redirect liquid flows. Alfa Laval’s sanitary mix-proof valves, which prevent product contamination from other non-sanitary fluids, are delivered as complete solutions and complemented by intelligent control equipment.

Butterfly valves provide gentle treatment of low and medium viscosity products. Seat valves are characterized by a modular design with only a few movable parts which makes them highly reliable and hygienic. Aseptic diaphragm valves are ideally suited for use in sterile and ultra-hygienic processes, especially for the pharmaceutical industries.

The Alfa Laval range of pumps covers every need for gentle, precision pumping of all kinds of fluids of all viscosities in hygienic applications.

The centrifugal pumps combine high efficiency with careful product treatment. The positive displacement pumps can be found in virtually every industry where gentle, sanitary processing of viscous products is required. The liquid ring pumps are designed for pumping liquids containing air or gas.

The need to separate smaller and smaller particles from each other within a flow stream is becoming increasingly important in process industries.

Membrane filtration is the established solution to separate very small particles. Alfa Laval’s range of membranes covers four categories separating particles of different sizes from the feed liquid. The categories comprise:

• reverse osmosis
• nanofiltration
• ultrafiltration
• microfiltration
