High Pressure Gear Pump (HGP)

Description

PSI High Pressure Gear Pumps (HGP) feature a long-life, heavy-duty gear design that takes on the tough demands of high-torque polymer extrusion applications.  Whether working with restrictive dies or high viscosity plastic materials, the HGP delivers consistent performance where standard gear pump designs wear out or fail.  These highly efficient positive displacement pumps take on the pressure building function to deliver a precise linear volume of output.  This effectively takes the load off the extruder, reducing extruder amp draw and extending component life while delivering steady die pressure and uniform product gauge. The art is in the profile.  PSI High Pressure Gear pumps offer large diameter gear shafts and an optimized gear tooth profile to support the high torsional strength required when processing highly viscous or fractional melt-flow polymers.
