Designed for handling sensitive, abrasive and high and low viscosity fluids, the Alfa Laval Twin Screw Pump is ideal for use in hygienic applications in the dairy, food, beverage and personal care industries. Its quiet, virtually pulse-free, smooth and gentle operation makes the pump an excellent choice for handling sensitive products.
The Alfa Laval Twin Screw Pump combines process duties typically handled by positive displacement with CIP duties typically handled by centrifugal pumps. This provides a robust and reliable platform that offers greater process flexibility.
Two-in-one operation provides easy handling of process media of varying viscosities as well as CIP fluids. This simplifies piping and pump control, cutting costs and minimizing contamination risks.
Superior suction performance with excellent lift capability and low NPSHr provides installation flexibility and increases product recovery.
Quick, easy seal replacement with the pump in place is made possible, thanks to a cartridge seal with a truly front-loading, self-setting design. This maximizes process uptime and minimizes maintenance costs. An optional seal service kit program adds maintenance flexibility and cuts operating costs.

The Alfa Laval Twin Screw Pump features a clean, external stainless steel finish with profiled elastomers and mechanical seals fully surrounded by the product. Designed for maximum cleanability using FDA-conforming materials, the pump is both EHEDG- and 3-A certified.
The combination of optimized gearbox design and excellent hydraulic performance provides for quiet pump operation, minimizing noise emissions. Running temperature is also minimized, thereby increasing workplace safety.
Minimize maintenance costs and maximize process uptime. Seal replacement with the pump in place is quick and easy, thanks to a cartridge seal with a truly front-loading, self-setting design. An optional seal service kit provides maintenance flexibility and cuts costs. Easy access to timing gears whilst the pump is in position simplifies the process of screw retiming without requiring drainage of the gearbox oil or removal of the coupling and motor.
