Nordson Sealant Cartridge Dispensing Metering Applicator Pump System JetStream This is good stuff. This is awesome metering system for adhesive needs. Just wonderful. We think this was built as a prototype, or pre-cursor, to the powerful JetStream Line of Nordson sealant systems. This was meant for areospace applications (Boeing originally had this for them, but canceled the project), but this may have other applications, you will know. it was designed for pre-mixed cartridges to load, in the rear. Very nice. For this listing I am only selling the pump or dispenser, but I have another listed that is the complete assembly, ready to attach to robotic arm. please ask questions.
