Single screw / Melt pump – V1

Introducing our first single screw / melt pump platform

Our single screw / melt pump platform is a high-performance extrusion solution for various applications. Designed for precision and versatility. The extruder comes equipped with a melt pump and is seamlessly controlled by the advanced “Flow-Connect” controller developed by flowlink.

Key Features

Height-Adjustable Frame: The extruder package is mounted on a height-adjustable frame for easy implementation in various extrusion setups
Horizontal tooling plate: The melt pump is mounted to an adjustable tooling plate to allow easy changeovers, cleaning, and maintenance tasks. This design enhances operational flexibility and convenience.
Compact and Mobile: The entire extrusion system is designed to be compact and mobile, weighing less than 150 kg, making it highly adaptable for various setups and environments.
Small size / High performance: Output flow up to 15 – 20 kg/hr, max. pump output pressure 350 Bar

Benefits of the Melt Pump:

The extruder feeds the melt pump at a operator defined inlet pressure while the pump controls the output flow of the extruder.

Consistant plastification: The setup keeps the pump inlet pressure at a constant – user defined value to ensure a consistant melt quality.
Consistent Pressure and Temperature: The pump cleans up the melt flow and compensates pressure fluctuatons.
Increased Pressure Output: The integrated melt pump allows the setup to achieve an output pressure up to 350 bar.

Additional Advantages of the Melt Pump in Processing:

Pulsation and swirl Reduction: The melt pump effectively compensates the pulsation and flow swirl caused by the extruder screw. This to ensure a smoother and more controlled extrusion process.

The Flexible Frame Design:

The horizontal adjustment feature of the frame offers flexibility for integrating various auxiliary equipment between the extruder and pump, including:

Static mixers
Breaker plates/filters (comes standard to protect the pump)
Valves and restrictions
Measuring equipment
