Its modular design, combined with Graco technologies and precision dispensing capabilities, gives you a system that is advanced and reliable yet affordable. Static, dynamic, or impingement mixing options, along with positive displacement pump technology, will improve throughput while reducing scrap and rework. This system provides accurate, on-ratio dispensing of materials at a constant pressure or flow rate. It offers precision dispensing that reduces material waste and lowers rework.
