The small laboratory extruder melt pump is a precision auxiliary device commonly used in polymer material research and development. It is primarily employed for small-batch melt transfer, pressure stabilization, and flow metering applications.
At its core, the small laboratory extruder melt pump functions as a gear pump. It achieves melt transfer through a pair of meshing gears rotating within a sealed chamber. When the drive gear rotates the driven gear, negative pressure forms in the suction chamber, drawing material from the upstream extruder. The meshing gears then forcefully push the material toward the outlet, generating stable high pressure. Flow rate is linearly adjusted by precisely controlling the gear rotation speed.
