Product catalog summary
Introduction
The document discusses the benefits and functionalities of the Xaloy Melt Pump, a device used in extrusion lines to improve gauge control and eliminate issues such as extruder surge and screw beat. The pump is positioned between the extruder and die, enhancing the efficiency of polymer processing.

Specifications and Features
The Xaloy Melt Pump is a positive displacement device that ensures consistent pressure and volume delivery to the die. It is not designed for mixing or melting but excels in building pressure and metering polymer output. The pump's precise construction allows for accurate volumetric metering, with each gear tooth carrying a repeatable amount of polymer melt.

Benefits
  • Material savings
  • Increased output and extruder life
  • Faster start-ups and lower processing temperatures
  • More accurate gauge control and reduced scrap
  • Lower shear stress and capability to process recycled materials
  • Fast paybacks and availability in various sizes for different products/extruders

Control and Integration
The Xaloy EMPAC Control system closes the loop from pump inlet pressure to extruder drive, monitoring downstream pressure to prevent issues from line stoppages. The system allows for production line flexibility, enabling the processing of multiple polymers with the same screw and shortening start-up times for difficult materials.

Options and Accessories
  • Adaptors, controls, and drive systems
  • Stands and internal fluid channels for heat/cool regulation
  • Manual, hydraulic, and continuous screen changers
  • Static mixers and divert valves

Technical Specifications
The document provides detailed specifications for various models of the High Pressure Melt Pumps (MHDP), including throughput rates, heater requirements, and pump weights. The maximum operating pressure is 10,000 psig, with a maximum temperature of 650°F.

Global Presence
Xaloy has a worldwide presence with sales and service offices in the United States, Europe, Thailand, Japan, China, and India, supported by a global network of agents.
