Application
Vacuum pumps for extruder degassing and extrusion
In the degassing zone of the extruder, vacuum draws water vapour, air and volatile substances out of the plastic melt before it passes through the die; after the extruder, vacuum holds the profile or pipe in shape and to size in the calibration tank. Edwards describes the removal of water vapour and gases from the melt, Atlas Copco the constant vacuum for dimensional accuracy in calibration. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 377 models from 5 manufacturers.

In short
Extruder degassing and extrusion: the key facts
- DegassingEdwards describes extruder degassing as the removal of water vapour and gases from the melt and names GXS, EDS and the liquid ring series LR1A, LR1C and LR1D; for dry-running pumps in extruder degassing, Edwards names 3–3,500 m³/h and ultimate pressures down to 4×10⁻⁴ mbar.
- Process pressureFor masterbatch production and compounding, Leybold names a process pressure below 50 mbar (EXTRUVAC VD) and, for small and medium-sized extruders, the CLAWVAC (EXTRUVAC CP) as an alternative to liquid ring pumps.
- CalibrationAtlas Copco describes the constant vacuum in the vacuum calibration tank for dimensional accuracy and names 100–200 mbar(a) with GHS VSD+ for corrugated pipe production; according to Elmo Rietschle, vacuum calibrators ensure shape and dimensions.
- SeriesFor profile, film and sheet extrusion and compounding, Busch names MINK, DOLPHIN, COBRA and HUCKEPACK, and for calibration also SAMOS; Pfeiffer Vacuum names HiLobe; Atlas Copco DZS, DWS, AWC, LRP VSD+ and GLS.
Operating principle
How it works: Extruder degassing and extrusion
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- MeltingThe screw plasticises the granulate; moisture and volatile substances are released in the melt.
- DegassingIn the degassing zone, according to Edwards, the vacuum draws water vapour and gases out of the melt; for compounding, Leybold names process pressures below 50 mbar.
- CalibratingAfter the die, the vacuum calibration tank keeps the profile dimensionally stable and true to size (Atlas Copco); for corrugated pipes, Atlas Copco names 100–200 mbar(a) in a moving vacuum mould.
Vacuum and sizing
Extruder degassing and extrusion: how much vacuum is needed
What the manufacturers say about pressure, pumping speed and sizing.
Which vacuum
For masterbatch and compounding, Leybold names process pressures below 50 mbar; for dry-running pumps in extruder degassing, Edwards names ultimate pressures down to 4×10⁻⁴ mbar; Atlas Copco 100–200 mbar(a) for corrugated pipe production.
Which suction capacity
For dry-running pumps in extruder degassing, Edwards names 3–3,500 m³/h.
What determines the sizing
The size of the extruder and the process: Leybold names CLAWVAC for small and medium-sized extruders and VARODRY (EXTRUVAC VD) for small extruders with less demanding processes. Busch distinguishes profile, film/sheet extrusion and compounding (MINK, DOLPHIN, COBRA, HUCKEPACK) from profile calibration (DOLPHIN, MINK, SAMOS).
What the manufacturers point out
They point to water vapour and gases in the melt (Edwards), to a stable vacuum in the degassing zones for compounding and masterbatch (Edwards) and to the alternative to liquid ring pumps (Leybold). For confectionery, Busch describes vacuum extrusion, which draws air bubbles out of the mass (MINK, DOLPHIN, and in the product finder also R5).

Extruder degassing and extrusion: where the manufacturers name it
The manufacturers list these uses on their own pages.
Plastics and recycling
All seven manufacturers name plastics extrusion: Edwards and Leybold describe the degassing of the melt, Atlas Copco, Elmo Rietschle and Busch vacuum calibration, while Becker and Pfeiffer Vacuum list extruder degassing without describing it.
Confectionery and bakery
Busch describes the vacuum extrusion of confectionery masses, in which air bubbles are drawn out of the mass, with MINK and DOLPHIN.
Frequently asked questions
Extruder degassing and extrusion: frequently asked questions
How does extruder degassing work?
In the degassing zone of the extruder, the melt is under vacuum. According to Edwards, water vapour and gases are removed from the melt in the process; Busch describes that the vacuum removes gases and ensures quality. A separator keeps condensate and entrained melt away from the pump.
Which vacuum pump for extruder degassing?
Leybold names CLAWVAC (EXTRUVAC CP) for small and medium-sized extruders as an alternative to liquid ring pumps. Edwards names GXS, EDS and the liquid ring series LR1A, LR1C and LR1D, Busch MINK, DOLPHIN, COBRA and HUCKEPACK, and in the product finder also R5 and PANDA/PUMA. Atlas Copco lists DZS, DWS, AWC and LRP VSD+, Pfeiffer Vacuum HiLobe.
How much vacuum does extruder degassing need?
For masterbatch production and compounding, Leybold names process pressures below 50 mbar. For dry-running pumps in extruder degassing, Edwards names ultimate pressures down to 4×10⁻⁴ mbar and pumping speeds of 3–3,500 m³/h. For calibration, Atlas Copco names 100–200 mbar(a) for corrugated pipes.
Which vacuum pump for the vacuum calibration of profiles and pipes?
For profile calibration and vacuum calibration, Busch names DOLPHIN, MINK and SAMOS. Edwards lists the liquid ring series LR1A, LR1C and LR1D, Atlas Copco GHS VSD+ for corrugated pipe production. Elmo Rietschle describes that vacuum calibrators ensure shape and dimensions, without naming a series.
Liquid ring or dry vacuum pump for extruder degassing?
Both are named. Leybold presents the CLAWVAC as an alternative to liquid ring pumps for small and medium-sized extruders; alongside the dry-running screw vacuum pumps GXS and EDS, Edwards also names the liquid ring series LR1A, LR1C and LR1D; Atlas Copco lists the DZS claw vacuum pumps, the DWS screw vacuum pumps and the AWC and LRP VSD+ liquid ring vacuum pumps.
Why must gases and water vapour be removed from the melt?
Gas that remains in the melt forms bubbles and defects in the profile, the film or the sheet. Busch describes that the vacuum removes gases and thus ensures quality; Edwards names degassing in film and sheet production from PE, PP, PA and EVOH.
Which vacuum pump for compounding and masterbatch?
For this, Leybold names VARODRY (EXTRUVAC VD) at process pressures below 50 mbar, for small extruders with less demanding processes. Edwards describes a stable vacuum in the degassing zones as a requirement. For extruder compounding, Busch names MINK, DOLPHIN, COBRA and HUCKEPACK.
What vacuum does corrugated pipe production need?
Atlas Copco names 100–200 mbar(a): a moving vacuum mould shapes and cools the pipe; the GHS VSD+ is named.
What is vacuum extrusion in confectionery?
Busch describes vacuum extrusion in confectionery production: air bubbles are drawn out of the mass. MINK and DOLPHIN are named, and in the product finder also R5.
What to do when the vacuum in the degassing zone fluctuates?
For compounding and masterbatch, Edwards names a stable vacuum in the degassing zones as a requirement, Atlas Copco a constant vacuum for calibration. A control valve upstream of the pump or a frequency-controlled pump – Atlas Copco names GHS VSD+ and LRP VSD+ – holds the pressure; separators and filters must be clear so that the pump retains its pumping speed.
A single pump or a central vacuum system?
A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.
Does Ehrler & Beck also supply spare parts and service?
Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
