Superior performance in a compact package

Clean, compact & capable - Looking for compact yet powerful pumping performance to drive your R&D projects forward?

It’s time you discovered the advantages of clean, dry, and oil-free scroll technology!

The Leybold SCROLLVAC 3S plus extends the Leybold range of scroll pumps, combining high pumping speed with good ultimate vacuum in a compact, flexible, quiet, and reliable package.

A technology requiring very little maintenance...

The SCROLLVAC 3S plus is as easy to use as it is to integrate in your laboratory setting. As such, it offers a clean alternative to oil-sealed rotary vane pumps and an ideal dry solution for backing the Leybold TURBOVAC i range of turbos.


With its high build quality, outstanding performance, flexible design, and compact footprint, the SCROLLVAC 3 and SCROLLVAC 3S plus are ideally suited to smaller-scale laboratories and R&D applications.

  • Universities
  • Research institutions
  • Small system builders and OEMs
  • Clean industrial application
  • Leak detectors


Main benefits


The pump that packs plenty of punch
The SCROLLVAC 3S plus gives you all the advantages of scroll pump technology in a clean, dry, and compact package. All the clean, dry, high-performance pumping without the oil to worry about.

  • Less hassle
  • Less risk
  • Less maintenance
  • Less running costs
  • Less environmental impact



Extending the range of advanced Leybold scroll pumps, the SCROLLVAC 3S plus is optimized for backing the Leybold TURBOVAC i range of turbomolecular pumps. Making it a great choice for small-scale R&D applications.

  • More choice
  • More modular building blocks
  • More cost-effective solutions



Small on footprint, big on performance
Weighing in at just 8kg, the SCROLLVAC 3S plus is the smallest in the range of Leybold dry scroll pumps. But don’t be fooled by its size! With peak pumping speeds of up to 3 m3/h at 50Hz (or 3.5 m3/h at 60Hz) and a typical ultimate vacuum of 0.1 mbar, the SCROLLVAC 3S plus is a very capable and dry alternative to diaphragm pumps.

  • Higher pumping speeds & better ultimate vacuum in a light, compact, & reliable package.



Plug, play, and repeat
The small footprint and light weight of the SCROLLVAC 3S plus make it easy to combine with your other Leybold products and integrate into your system. Supplied as standard with DN 16 ISO-KF inlet and push-fit exhaust connections along with mains-driven motor, IEC connection, and an on-off switch for easy operation.



Just fit and forget
Oil-free operation means longer service intervals and overall lower total cost of ownership. Unlike oil-sealed rotary vane pumps, all you have to do is replace the tip seal of your SCROLLVAC 3S plus every couple of years. Which you can easily do yourself.



The SCROLLVAC 3S plus can be mounted either horizontally or vertically, if required. Optional mounting brackets and base plates make it even easier to attach the pump to any structure. The base plate can also be used to retrofit your SCROLLVAC 3S plus onto an existing Leybold Turbocart. So you can upgrade your existing system to scroll technology quickly and easily.



Built-in manual gas ballast
Does your exhaust gas contain some moisture? Not to worry. The built-in manual gas ballast on your SCROLLVAC 3S plus is capable of handling a fair amount of water vapor while still maintaining a good ultimate vacuum for reliable and consistent performance.



High speed, low vibration
The SCROLLVAC 3 plus and SCROLLVAC 3S plus are optimized for low vibration and quiet operation. Both models utilize a full fan cowl design. An exhaust line can also be fitted directly to the standard push-fit exhaust fitting. Otherwise, an exhaust silencer filter accessory can be used for free-standing operation. This silencer accessory is supplied as standard with the SCROLLVAC 3S plus.



Full-feature design for a reliable seal
Both the SCROLLVAC 3 plus and SCROLLVAC 3S plus come fitted with a built-in exhaust valve as standard, just like the larger SCROLLVAC pumps, providing effective protection from rapid pressure rise in the event of a power failure. For extra system protection, the SCROLLVAC 3S plus offers the added peace of mind of a fast-acting solenoid inlet valve to isolate the pump from your system and preserve the vacuum inside your system. Already have protection valves built into your system? The standard SCROLLVAC 3 plus without built-in inlet valve may be better suited to your requirements.

Delay relay
And when the power is restored, a delay relay switch built-in to the SCROLLVAC 3S plus prevents the inlet valve from opening for 10 seconds to allow the pump get up to speed and evacuate itself.
