What a Gear Pump Can Do

Gear Pumps For Polymer Extrusion Applications: 

• Control gauge to less than +/-0.25% (typical)!  Gear pumps almost entirely offset the effects of head pressure variation. Pumping efficiency is typically 99.5% or better.
• Up to 50:1 reduction in die inlet pressure swings! Accurate, repeatable dimensions across your profile through constant volumetric output (cc/rev). Die pressure swings are normally held to 0.5 -1%.  However, without a gear pump, the extruder can generate die pressure swings of 10-15%.    
• Use more reclaim – lots more. PSI gear pumps flatline a great deal of surge from the extruder barrel since they take over the pressure-building function for the die.
• Boost your extruder’s output – we’ve provided gains greater than 25%! by lowering extruder back pressure. Example:

If your average line rate is 2,000 lbs./hr., a 10% production increase (our typical minimum gain) yields 200 lbs./hr. of added production.  Over a 5,000 hour production year, the increase adds up to 1,000,000 lbs. of additional product available for sale!  Try multiplying that by your profit per pound! 

• Gets you into production faster (or faster yet, with optional haul-off control) with touch-button automated start-up – yields more saleable product and much less scrap!
• Lower product cost! Less material give-away due to tighter tolerance extrusion.
• Cut the scrap!  Consistent output and dimensional stability mean more saleable product to keep your valued customers happy, less off-spec and less scrap.  
• Increases the life of your extruder components since the pump takes the pressure load off the extruder. Barrels, screws, bearings, gearboxes last longer!
• Saves you energy! Adding a pump typically reduces the entire line amp load.  Small consistent savings add up to big savings over time.
