Metering pump
The metering pump controls the flow of the melt and determines the weight of the pellets. The material enters the pump
casing (1) (heated by elements EH7) through a suction flange (6) and is pushed by suitable gears (2) (driven by geared
motor M8) towards a delivery flange (7). The latter then sends the material to the feed tube.
The pressures of the suction and delivery lines of the material is controlled by transducers BP1 and BP2. The pump
temperature is controlled by thermocouple BT7.
NOTE
The metering pump is not provided in the 50 kg/h extruder.
