Melt Pumps for Biodegradable Agricultural Film

Melt gear pumps for extrusion systems are referred to as melt pumps, also known as melt metering pumps or extrusion pumps, which can be used in various extrusion industries, such as sheet, plate, pipe, film, pelletizing, drawing, cable, co-extrusion, mixing, precision extrusion and other industries. It is suitable for the extrusion and transportation of thermoplastic high viscosity polymer melt; it is generally installed between the outlet of the extruder and the die head as a melt metering pump; it can also be installed in the polymer melt pipeline as a booster pump.

Extruder melt pump material

Gear type: helical or straight toothed cylindrical gears.

Seal structure: melt dynamic seal + packing seal, mechanical seal, with cooling melt dynamic seal

Pump casing: stainless steel/alloy steel/corrosion-resistant alloy

Gear: Nitrided steel / tool steel / stainless steel + coating / corrosion-resistant alloys

Bearing: tool steel/copper alloy/stainless steel + coating/corrosion-resistant alloy

Extrusion melt pump parameters

Conveying medium viscosity: 1～40000Pa-s

Suction pressure: 0～30MPa

Output pressure: 0～40MPa

Permissible differential pressure: 25MPa

Operating temperature: ≤350°C

Heating method: electric heating/heat medium runner heating

Extruder melt pump is mainly composed of pump casing, front and rear side cover, gear shaft, sliding bearing and shaft seal, etc.; it has the advantages of precise structure, high accuracy, small pressure and flow rate pulsation and long service life.
