Vacuum Pump Spares for Glass

Vacuum pump spares for architectural glass coaters (low-E, anti-reflective, solar-control), automotive glass plants, VIG (vacuum insulating glazing) lines, and display-glass production. Edwards iXM/iXH, Leybold DRYVAC and MAG, plus large mechanical boosters in UK stock.

How vacuum is used in Glass

Vacuum pumps are used in the glass industry for thin-film coating of architectural and automotive glass (low-E, anti-reflective, solar-control), vacuum insulating glazing (VIG) manufacture, vacuum-assisted glass forming and lifting, cathode ray tube and display glass production, and large-scale PVD/sputtering chambers in glass-coating lines.

Applications

Where vacuum is used in Glass

We supply spare parts to support every vacuum-based process in this sector — from frontline production equipment to laboratory and quality-assurance instrumentation.

Architectural glass coating

Large-area magnetron sputtering of low-E, solar-control, anti-reflective, and self-cleaning coatings on float-glass production lines.

Automotive glass coating

Heated windscreens, head-up display reflective coatings, and IR-reflective solar coatings on vehicle glazing.

Vacuum insulating glazing (VIG)

Sealed double-pane glass with an evacuated cavity (~10⁻³ mbar) for super-insulating windows.

Display glass manufacturing

Coating and processing of glass substrates for LCD, OLED, and touchscreen displays.

Vacuum-assisted glass forming and bending

Mould-cavity evacuation during automotive windscreen bending and laminate manufacture.

Vacuum lifting of float glass

Suction-cup end-effectors on robotic glass handling — large-area vacuum cups for full sheets.

Solar PV manufacturing

Thin-film deposition on PV cover glass; vacuum lamination of crystalline silicon modules.

Glass fibre production

Vacuum-controlled fibre forming for insulation and composite reinforcement.

Pump Selection

Which pump types are used and why

Different applications in glass drive different pump-technology choices. We support the full breadth of pump types installed in this sector.

Brand Affinities

  • Edwards GXS and iXH on glass-coating production lines
  • Leybold DRYVAC and SCREWLINE on architectural and automotive coating
  • Leybold TURBOVAC MAG on display glass high-vacuum chambers
  • Pfeiffer HiPace on display and optical coating
  • Pfeiffer OktaLine and Edwards GXS Roots boosters on large coating chambers
  • Busch and Atlas Copco side-channel blowers on glass-lifting end-effectors

Large dry screw pumps and dry roots multi-stage

Glass-coating lines need oil-free roughing to maintain coating quality — Edwards GXS/iXH, Leybold DRYVAC/SCREWLINE.

Mechanical boosters (Roots blowers)

High-throughput coating chambers — boosters in series with primary dry pumps to maintain pumping speed at low pressure.

Turbomolecular pumps

Display glass and high-end optical coating where ultra-low base pressure (10⁻⁷ mbar) is required.

Side-channel and regenerative blowers

Vacuum-lifter handling of float glass — high cycle, low vacuum level, oil-free.

Why Urgency Matters

The cost of vacuum downtime in glass

Float-glass coating lines run as continuous production — a single dry-pump failure on a coater stops the entire line, with downtime typically £50k–£200k per hour in lost output plus the cost of out-of-spec glass scrapped during ramp-down and re-establishment. Glass-coating chambers are temperature-cycled to clean, so a recovery from outage adds hours of re-establishment before quality glass restarts. JIT supply with held exchange stock for the largest dry pumps is a real differentiator.

Common Failure Modes

Coating-residue powder accumulation in dry pump mechanism

Full mechanism overhaul kits, exchange units

Booster bearing wear under continuous high-duty cycle

Bearing kits, gear sets, timing-gear oil

Turbo bearing failure from particulate ingress on chamber vents

Bearing service kits or full pump exchange

Vacuum-lifter check-valve wear from high-cycle duty

Inlet check valve assemblies and seal kits

Frequently Asked Questions

Common questions about vacuum spares for glass

Large dry screw pumps (Edwards GXS/iXH, Leybold DRYVAC, Leybold SCREWLINE) for clean oil-free roughing, with mechanical booster Roots blowers in series for pumping speed. Turbomolecular pumps are added when ultimate base pressure below 10⁻⁵ mbar is required for the coating chemistry.
