Dry Scroll Pumps

Dry scroll vacuum pumps are positive displacement pumps that use two spiral-shaped scrolls, one fixed and one orbiting, to trap and compress gas molecules. They are oil-free, low maintenance pumps that are commonly used for clean vacuum applications. Since they do not rely on oil for sealing and lubrication, they eliminate the risk of oil contamination and leakage, making them an environmentally friendly choice.

We in Edwards are driving scroll technologies to its best and we are committed to offer the most sustainable solution now and in the future.

mXDS Scroll Pumps

Edwards is extending our small dry pump portfolio. mXDS3 continues our scroll pump experience filling the performance gap and giving more choice to System builders and OEMs. A small dry alternative to oil sealed rotary vane pumps and diaphragm pumps of a similar capacity. mXDS3 are offered as standard or configured with an inlet valve accessory and exhaust silencer/filter to become the mXDS3s.

mXDS3 - 230V 1Ph 50/60Hz

This standard variant of the mXDS3 comes with a single phase 230V 50/60 Hz motor.

Features and Benefits

Flexibility - The compact and lightweight mXDS3 weighs in at just 7.8 kg and comes with a purpose-made carry handle making it highly portable. For system builders, the pump can typically be mounted horizontally or vertically and for convenient connection, the inlet can be orientated vertically or horizontally with a push-fit alternative available as an accessory.
Performance - Edwards mXDS3 and mXDS3s dry scroll pumps deliver 3 m3/h peak speed and 0.1 mbar ultimate. The pumping speed and good ultimate vacuum make these pumps well suited for backing turbomolecular pumps. These small scroll pumps have a gas ballast facility incorporated in the design as standard for water vapour handling and an exhaust valve just like the larger nXDS.
Environment - Edwards mXDS3 and mXDS3s are clean oil-free pumps with no oil to top up, replace or dispose of. They typically have a lower power requirement compared to similar capacity pumps making them great for energy savings, an ideal choice for helping to reduce your carbon footprint. The optimised fan cooling is beneficial in reducing noise for quieter operation and a pleasant working environment.
