Twin Screw

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 twin screw pump 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.

A robust, all stainless steel gearbox with timing gears located between bearings, provides an optimized bearing span. Balanced loading of the shaft assembly reduces vibration and noise, increasing component life and reliability.

The oil chamber design enhances bearing and gear lubrication, increasing bearing life and minimizing gearbox running temperature.

Easy access to timing gears, whilst the Twin screw pump is in position, simplifies the process of screw retiming; there is no need to drain gearbox oil or to remove the coupling and motor.

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.

An optional ATEX version enables use in hazardous zones.
