A manufacturer of melt pumps, polymer pumps, chemical pumps, screen changers, water ring pelletizers, jet cleaners, and static mixers, the group consists of what was formally Normag Gear Pumps, Extek Screen Changers, and Beringer.
Today, Xaloy spans every continent and is represented in over 50 countries. Manufacturing sites include Franklin, Massachusetts; Hickory, North Carolina; Ontario Canada; Heilbronn, Germany; Bensheim, Germany; and Gravendeel, The Netherlands. A network of direct offices that offer sales and service throughout United States, Europe and Asia Pacific supports these manufacturing sites.
Extrusion Line Synchronization Made Easy
With a Xaloy pump between your extruder and die, you can directly dial in gauge control. Thus eliminating extruder surge and screw beat at the die, the line requires far less fine tuning and attention.
Here’s why: Extruder screws are efficient for providing a melted mix flow, but are not as efficient at providing a consistent pressure and volume to the die.
A melt pump, while not a mixing or melting device, is extremely efficient at building pressure and metering the polymer output. The Xaloy Melt Pump is a positive displacement device which provides a linear output over a wide range of operating conditions. A closed-loop drive control varies extruder screw speed to assure an adequate amount of polymer to the pump regardless of inlet pressure variations due to extruder surge and screw beat.
Precise construction makes Xaloy Melt Pumps extremely accurate volumetric metering devices. Each melt “bucket” carries a precise, repeatable amount of polymer melt to the output side of the pump.
The additional control of a Xaloy Melt Pump installation also provides you with more production line flexibility, first by shortening start-up times on difficult materials and second, by expanding your operating ranges of temperature, pressure and line speed.
Xaloy Dynavision Control closes the loop from pump inlet pressure to extruder drive while monitoring downstream pressure to eliminate any problems due to downstream line stoppage.
Significant Material Savings
Add a Xaloy Melt Pump to your extruder and you will see a material savings while making the same product with the same polymer. The Xaloy Melt Pump reduces pressure and volume variations by a factor of 50 to 1. This flow damping means very accurate outputs of 1 percent variation or less. Without the melt pump, extruder variations can mean giving material away to meet spec.
Higher Product Quality
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 products price.
Less Scrap and Runs Regrind
Consistent on spec production has an enormous effect upon production and profits. Not only does more production go out the door, but your extruder line runs smoother and more efficiently even with 100% regrind. Void and thin spots disappear.
Reduce Load on Your Extruder
Install a Xaloy Melt Pump System and 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 Xaloy melt Pump.
Integrate the Systems
Put an Xaloy Screen Changer in front of the Xaloy melt Pump and further increase the productivity of the extrusion lone all from one company.and most important of all, your extruder producing again.
DBC continuous screen changer
Xaloy’s DBC Continuous Screen Changer provides continuous polymer flow and consistent, repeatable process parameters during screen changes. As polymer enters the screen changer the melt stream is divided equally and distributed through two rheologically optimized breaker plates. This method of filtration provides increased screen area as compared to single breaker plate screen changer designs and maintains a streamlined polymer flow path. Polymer merges back to a single melt stream as it exits the screen changer.
EH hydraulic screen changer
The EH Hydraulic Screen Changers were designed with the most impressive list of features available.
Designed using finite element modeling for operation up to 10,000 psi, pressure drops to 3,000 psi and processing temperatures up to 850°F.
Close coupling to the extruder is available with the standard bolt through extruder connection.
The EH screen changer comes fully assembled, pre-wired and requires only a single temperature control zone.
Xaloy provides full time, total support — without compromise, without exceptions.
Xaloy’s water ring pelletizer connects directly to the end of the extruder, Xaloy Screen changer or Melt Pump via a short coupled adapter allowing polymer to flow horizontally from the extruder to the in-line die plate. The rheologically optimized design minimizes polymer inventory between the extruder and die plate and evenly distributes polymer flow to each die plate hole. The result is a consistently uniform pellet.
Reclaim, masterbatch, and compounders will benefit by improved pellet quality during both short and extended production runs. The in-line design reduces inlet pressures which can allow for increased production rates. Polymer purges quickly through the in-line die plate for quick color changes, which maximize production time. The retractable cutter head allows quick access to change blades and remove die plates for cleaning or screw removal.
An open trough cooling system allows easy operator response to process changes. A new cylindrical pellet dryer provides improved 360° access to dryer rotor for cleaning and pellet removal. Pellet flow though the dryer is streamlined to eliminate pellet stagnation and promote efficient pellet drying. An integral dryer blower exchanges dryer air 50 times per minute to provide improved pellet dryness.
