Industry
Vacuum pumps for glass, ceramics and stone
In the container glass industry, vacuum forms bottles and jars; in ceramics, it removes air and gases from the raw clay before forming; in stone production, it holds slabs during forming, handling and polishing (Atlas Copco, Elmo Rietschle). For glass fibre production, Edwards names the handling of process dust. Below you can see which series the manufacturers themselves name for these tasks ā 171 models from 3 manufacturers.

In short
Glass, ceramics and stone: vacuum pumps ā the key facts
- IS machinesFor glass forming in IS machines, Atlas Copco names 150 to 300 mbar, 100 to 250 m³/h per section and 600 to 1,500 m³/h per machine, up to 4,000 m³/h, with the GHS VSD+; the moulds are evacuated through fine holes.
- Clay degassingFor degassing moist clay, Atlas Copco names the GHS VSD+ in the Humid version with Vapor Control Algorithm. For clay preparation and the extrusion of bricks and roof tiles, Elmo Rietschle names the L and C series.
- Pumping speedAtlas Copco specifies the GHS VSD+ series for the container glass industry at 350 to 5,400 m³/h, and for stone production on its own or with a booster.
- Less compressed airFor glass forming with vacuum instead of compressed air, Atlas Copco names faster forming and up to 5 times less air and energy.
Applications
Glass, ceramics and stone: what vacuum pumps are used for
For each application: what the vacuum does and which series the manufacturers name for it. The information comes from the manufacturersā own pages.
Clay degassing for bricks and ceramics
Before forming, the pressure in the degassing chamber is lowered; air and gases leave the moist clay, the clay becomes denser and the surface has fewer holes and bubbles (Atlas Copco). Elmo Rietschle describes vacuum extruders that remove air bubbles from the clay mix. For large quantities of clay, Atlas Copco names batch processing with the GHS VSD+; Leybold also names CLAWVAC and NOVADRY for ceramics and bricks.
Glass forming in IS machines
The moulds are evacuated through fine holes; forming becomes faster and needs less compressed air (Atlas Copco). Atlas Copco names 150 to 300 mbar, 100 to 250 m³/h per section and 600 to 1,500 m³/h per IS machine, up to 4,000 m³/h, with the GHS VSD+. Leybold lists glass bottle forming with the NOVADRY.
- Atlas CopcoGHS VSD+
Pressing, forming and polishing stone
For engineered and natural stone slabs, the material is vibrated under vacuum, the press is evacuated and the stone is held on the cutting table and during polishing (Atlas Copco). Atlas Copco names the GHS VSD+ for this, on its own or with a booster, and points out styrene as a contaminant.
- Atlas CopcoGHS VSD+ also names the DB blowers for vacuum tables
Handling and lifting slabs
Vacuum lifters grip heavy slabs, and vacuum grippers work on pick-and-place robots (Atlas Copco). For holding, lifting and transporting, Atlas Copco names the GHS 1202 to 2002.
- Atlas CopcoGHS VSD+ also names DVS, GVS A, DZS, DHS VSD+ and DB

Selection
Glass, ceramics and stone: choosing a vacuum pump
What the manufacturers highlight for use in this industry.
Moist clay
The raw clay releases moisture into the vacuum. For this, Atlas Copco names the GHS VSD+ in the Humid version with Vapor Control Algorithm, and Elmo Rietschle names the L and C series for clay preparation and extrusion.
Pumping speed per machine
For IS machines, Atlas Copco calculates with 100 to 250 m³/h per section and 600 to 1,500 m³/h per machine, up to 4,000 m³/h, at 150 to 300 mbar; the GHS VSD+ covers 350 to 5,400 m³/h.
Dust and styrene
For glass fibre production, Edwards names dry screw and scroll pumps for handling process dust. Atlas Copco points out styrene as a contaminant when engineered stone is pressed.
