Fimic pump boosts extrusion line performance

SPA screw pump Fimic’s SPA screw pump is designed to boost the performance of extrusion lines recycling plastics, including those processing challenging post-consumer resins (PCR). For compounding post-industrial materials, it can accept melt from a twin-screw extruder and boost the melt pressure as it flows into the filter, improving the filter’s output and avoiding backflow. For PCR applications requiring double filtration, a single-screw extruder feeds melt directly into a filter, then the SPA can be placed between the first filter and the second filter. In that arrangement, the SPA decreases the outlet pressure of the first filter, boosting its productivity, then rebuilds pressure as the melt enters the second filter. Fimic said the SPA, or “Screw Pump Antonio,” is named for Fimic employee Antonio Canaia, who created the company’s first automatic self-cleaning melt filter more than 20 years ago.

What’s new? The SPA, which is an alternative to traditional gear pumps.

Benefits Robust construction and lower operating costs. Gear pumps often need a filter to protect them from contaminants in recycled melt and require regular maintenance and periodic downtime to conduct expensive gear replacements. The SPA screw pump’s design makes it less prone to damage and provides longer life of wear parts than an equivalent gear pump.
