Oil-free scroll vacuum pumps

Completely oil-free vacuum pumps for use in diverse applications.

Oil-free scroll vacuum pumps of the SCROLLVAC plus family provide a flexible, robust, and simple vacuum solution. It is possible for the pumps to be used across a wide spectrum of applications. This includes general laboratory, light industrial and research applications, and some chemical applications.

The dry vacuum pumps of the SCROLLVAC plus family operate on the principle of a scroll compressor. A scroll pump consists of two engaged spiral forms. One scroll form is mounted eccentrically to the other and is made to move in an orbiting path relative to the fixed scroll. This creates crescent shaped volumes that are driven from the outside to the inside of the forms thereby pumping the gas.

SCROLLVAC plus are completely oil-free dry scroll pumps where increased pumping speed is combined with low ultimate pressures, low power consumption and low noise levels. Gas ballast allows for pumping of condensable vapors including water, solvents, dilute acids, and bases. 

SCROLLVAC plus small dry pumps also features the latest in tip seal technology allowing for significantly longer intervals between tip seal changes. The integrated smart drive with auto sensing voltage input, delivers optimized pumping performance globally. SCROLLVAC plus pumps are designed to be field serviceable. 

All SCROLLVAC plus dry pumps are ATEX certified to meet the requirements of group II category 3 equipment (ATEX II 3 G c IIB T4 internal). They are also CE, CSA/UL approved.

Addressing a wide range of applications

From general labs to research. Flexibility and choice are essential when selecting the right dry vacuum pump solution for your application. With SCROLLVAC plus you can choose within four different pumping speeds to best meet your specific requirements. The design of the SCROLLVAC plus separates the bearing mechanism from the pumping mechanism. This means the scroll forms provide clean, dry, lubricant-free pumping. At the same time the bearings operate in a benign atmospheric environment which contributes to the longevity of the pump. A simple to operate gas ballast enables the pump to effectively cope with vapor loads as well as gas loads. The gas ballast adapter accessory allows the introduction of inert gasses, either at full or reduced gas ballast flow. SCROLLVAC plus can be connected to an exhaust line: where this is not available an exhaust silencer may be fitted.

Effortless and easy to operate and maintain

This oil-free scroll vacuum pump is designed to be simple to operate whether manually or via remote control. Long service intervals make the SCROLLVAC plus an almost “fit and forget” solution. When it’s time to change the Tip seal: you can do this quickly and easily.

A pump with a positive environmental impact

SCROLLVAC plus is a hermetically sealed lubricant-free dry vacuum pump. This means there is no need to dispose of used oil. The smart drive also contributes to lowering the pump’s power consumption, making it environmentally friendly.

Quiet vacuum pump

An immediate improvement for your workspace! Low noise levels of below 55 dB(A) make for a pleasant workplace or laboratory environment where you can perfectly have a normal conversation.

Low cost of ownership

Its long service interval and low power consumption from a single sided scroll arrangement make the SCROLLVAC plus a perfect investment for the longer term.


Comes with several options to meet your specific needs

The standard SCROLLVAC plus variants have been designed to meet most general applications. 

The SCROLLVAC C plus variant has been designed for more aggressive applications: where the potential deterioration of the internal parts due to corrosion needs to be seriously considered. In combination with suitable purge gas flows the SCROLLVAC C plus models can be configured to handle corrosive solvents and chemicals.

The SCROLLVAC C models come with:

  • Chemical resistant exhaust check valve and gas ballast valve
  • Stainless steel inlet and exhaust flanges
  • Conversion kits are available allowing you to upgrade the standard variants.

For specific applications such as gas recovery or recirculation we offer a no-gas ballast version in order to reduce the potential for accidental leakage.

Our three-phase versions have no active electronics which makes them suitable for radiation environments.
