JR Series Staple Fiber & Polyester Melt Metering Pump
JR series gear metering pump is a high-precision fluid conveying
equipment specially designed for staple fiber, polyester melt, and
glue coating industrial scenarios. Adopting a compact one-in
one-out structure, it delivers stable flow output and excellent
pressure resistance, widely used in extrusion, pipeline
pressurization, polyurethane foaming, PUR hot melt adhesive
spraying, and other precision processes.
