This new generation of gear pumps is designed for film, sheet, profile, fiber, compounding, recycling, polymerization and hot-melt applications.

BKG BlueFlow gear pumps This new generation of gear pumps from Nordson Corp. is designed for film, sheet, profile, fiber, compounding, recycling, polymerization and hot-melt applications. The product line has three different series: EP pumps for standard extrusion, MP for processes that require frequent color changes or heat-sensitive polymers, and RP for discharge out of vessels and reactors where no vacuum is applied. The gear pumps can achieve throughput ranges up to about 26,500 pounds per hour, come with either electrical or fluid heating, and are available in US or EA (Europe and Asia) models to account for regional differences in connections and sealing.

What's new? The product line, which was introduced at the K show in October.

Benefits Efficiency, flexibility and precise control. The pumps have better sealing performance and more sealing options (air- and water-cooled systems, as well as designs with cooling fins); and improved control over melt parameters thanks to pressure and temperature sensors at both the inlet and outlet sites. They also offer greater melt delivery efficiency: Compared to previous pumps, they allow users to either get 15 percent greater throughput without increasing pump rpm, or achieve the same throughput while reducing pump speeds to reduce shear stress on the polymer.
