The Unimark auger screw pump has been developed to give precise flow to our extrusion shoes. The pump is enclosed in an oil jacket and driven by a variable hydraulic motor system. The benefit is constant width and thickness, with excellent start and cut-off to extruded lines. The Unimark pump can be fitted to all of our thermoplastic machine range. Unimark operates on policy of continual research and development, therefore specifications can change without notice. The images are indicative.
