//  Benefits: //

For years, polymer processors have utilized gear-pump-assisted extrusion to solve critical issues in the diverse plastics industry.

The Pnh melt gear pump optimizes the extrusion process by allowing the screw to melt and homogenize the polymer. As the pump generates the needed pressure, it relieves the extruder of work; therefore, reducing heat from the shear, lowering the torque required, and eliminating surging. All this optimizes the performance of the extruder and offers the following benefits:

  • Higher Product Quality

Melt pumps effectively isolate the die from upstream fluctuations. No matter what you are extruding, better pressure and volume control will result in greater product uniformity. Uniformity translates to better quality, which may mean new customers and/or a higher product price.

  • Controlled Melt quality

Melt pumps allow the back pressure on the extruder to be regulated to minimize residence time and stabilize the plasticizing action of the extruder. This achieves a controlled melt quality and reduced melt temperature.

  • Increased Production

Melt pumps generate a substantial portion of the pressure required at the die head, allowing the extruder to operate at lower backpressure. Typically, each 70 bar in back pressure on the extruder will result in a 10 percent increase in melt throughput for a given speed.

  • Significant Material Savings

Add a melt pump to your extruder and you will see material saving while making the same product with the same polymer. The melt pump reduces pressure and volume variations maximum by 1%. This produces a narrower finished product gauge variation which allows tolerances to be adjusted to minimize giveaway.

  •  Eliminates surging and screw beat

Effectively handles problems caused by melt density or extruder parameters.

  • Increased Extruder Flexibility

Melt pumps and extruder combination allow for controlled operation under varying conditions such as regrind levels, polymer type, screw design, die head pressures, temperatures, etc. Consistent on-spec production has an enormous effect on production and profits. Not only does more production to go out the door but your extruder line runs smoother and more efficiently even with more regrind and recycled materials. Void and thin spots disappear.

  •  Streamlined operation and startup

The closed-loop controller and positive displacement gear pump provide metered flow to the die while providing an easy operator interface. Extended Extruder Life Melt pumps reduce the load on your extruder. This load reduction can translate into higher output rates, Lower melt temperatures, lower energy consumption, longer screw and barrel life. In summary, maximize the efficiency of your extruder with a melt pump.

  • Lower Operational Cost

Melt pump provides a more efficient method of conveying extruded, eliminating material giveaway, reducing scrap and increasing production per KG of extruded, etc.
