Equipment Features
- Pulsation-free smooth flow The single-screw rotor delivers an extremely smooth, pulsation-free flow with stable flow rate, ideal for precision and metering applications.
- High-viscosity handling Conveys high-viscosity and shear-sensitive materials that centrifugal pumps cannot handle, without damaging the material structure.
- Gentle on sensitive products Low-shear positive displacement action protects the texture and active ingredients of sensitive food and pharmaceutical products.
- Self-priming capability Strong self-priming performance allows reliable start-up and stable operation over a wide viscosity range.
- Food-grade hygienic design 304 / 316L stainless steel wetted parts with sanitary construction, easy to clean and compliant with food and pharmaceutical standards.
Working Principle
A single helical screw rotor rotates inside an elastic stator, forming a series of sealed cavities. As the rotor turns, these cavities move continuously from the inlet to the outlet, carrying the material forward at a constant rate. This positive displacement action produces a steady, pulsation-free flow that is independent of pressure, making it ideal for viscous and shear-sensitive liquids.
