Leybold SCROLLVAC
SCROLLVAC plus is Leybold's oil-free scroll vacuum pump for continuous operation. The pumping speed of 3–20 m³/h covers laboratory and research use as well as lighter industrial applications where process cleanliness matters.
Applications and suitability
SCROLLVAC plus is suited to applications where the vacuum process must not be exposed to oil. The pump's bearings are fully separated from the pumping chamber, so no lubricant can enter the chamber at any stage of operation. Typical applications:
- Electron microscopy (SEM)
- Particle accelerators and high-energy physics
- Research and development
- Backing pump for turbomolecular pumps
- Centrifuges
- Chamber evacuation
- Chemical applications, such as gel drying and solvent recovery
- Cryopump regeneration (high water vapor pumping capacity)
For more demanding chemical processes, the SCROLLVAC C plus version is available, featuring a chemical-resistant exhaust check valve and gas ballast valve, along with stainless steel inlet and outlet flanges. The C version is suitable for pumping corrosive solvents and chemicals with purge gas.
Models and technical data
The SCROLLVAC plus series covers six size classes: 3, 3S, 7, 10, 15, and 18. The smallest model, the 3 / 3S plus, is designed for small-scale research and development work and uses a DN 16 ISO-KF connection. The series' larger models, 7–18 plus, use a DN 25 ISO-KF connection on both the inlet and outlet, and all share the same rotation speed. The single-phase version works worldwide on the same unit thanks to its universal voltage rating (100–127 V and 200–240 V), while the three-phase version is also available as an electronics-free option for radiation and magnetic field applications.

Why SCROLLVAC?
Fully oil-free pumping: The bearing mechanism is hermetically separated from the pumping chamber, so no lubricant can enter the process at any stage of operation.
Long service intervals: No shaft seal to wear out, which extends the service interval and improves sealing compared to conventional solutions.
High water vapor tolerance: The gas ballast enables pumping of condensable vapors, such as water and solvents, without internal condensation.
Quiet operation: Melutaso 55 dB(A) kaikissa malleissa sopii myös laboratorioympäristöön.
ATEX certified: The Ex II 3 G c IIB T4 classification allows use in hazardous areas without additional equipment.

Lifecycle from purchase to maintenance
SCROLLVAC is designed for continuous operation without specific usage restrictions, and its design has been kept simple for ease of maintenance. The lifecycle from procurement to maintenance proceeds smoothly, stage by stage, when acquisition, commissioning, maintenance, and contingency planning are handled under one roof.
Purchase and commissioning
Initial period and warranty
Preventive maintenance
Since the pump is oil-free, maintenance focuses on replacing the tip seal. The tip seal can be replaced by the user, and service kits and standard spare parts are available directly from our stock.
Managing downtime
If your vacuum process can't tolerate an unexpected shutdown, we arrange a replacement pump for use until we repair the fault. Field service is also available through us.
