  • Lower processing temperatures
  • Reduced scrap
  • Increased life on extruder screw & barrel
  • Lower energy consumption
  • Lower shear stress

The PSI High Pressure Gear Pump (HGP) is ideal for the most demanding extrusion processes. The HGP is capable of processing highly viscous, filled materials and can operate at pressures up to 10,000 psi (7,500 ΔP). The pump system is mounted between the extruder and the die head to eliminate any process variations initiating in the extruder. The HGP will accurately meter polymer and pressure to the die providing consistent output, precise gauge control, and ultimately a superior end product. PSI manufactures complete pump systems, controls, and all interfacing equipment which can be mounted on a custom designed support stand, or supplied as individual components.
