WOB-L piston pumps are reliable dry vacuum/pressure pumps for physical and aqueous vapor applications, where corrosion resistance is not required.
These pumps include vacuum regulators, pressure regulators (single head models only) and gauges for simple adjusting and monitoring of vacuum level and delivery pressure.
Selected models can be used as pressure pump.
0.55 - 4.9 m³/h (9.2 - 83 l/min)
292 - 10 mbar
Edwards nXDS Dry Scroll pump provides excellent vacuum levels, vapour pumping capability while been quiet and offering ultra-low maintenance intervals that even the customer can carry out. Overall it provides superior performance and reliability together with very low running and maintenance costs. The nXDS is a smart mid and long-term investment for any customer in terms of costs.

A muffler ensures a very low sound level during pump operation.
With vacuum, pressure regulators (single head) and gauges for simple adjusting and monitoring vacuum level and delivery pressure.
An inlet water trap with a float ball rises to seal the pump if needed.
High quality Piston Technology offers low maintenance to the pump and an efficient continuous running.
Light weight and compact to use as portable system on laboratory applications.
Selected models can be used as pressure pumps.
The nXDS has very low levels of noise and vibration as standard.
This dry scroll pump achieves unique levels of vacuum.
The nXDS uses a patented bellows isolation mechanism making it totally dry.
Tip seal changes from 2.5 years under 24/7 operation, and bearing changes every 5 years.
It's gas ballast capability enables is to pump vapours while avoiding internal condensation.
