Crawley-based Edwards has unveiled its new generation of dry scientific vacuum pumps which the company claim require less maintenance.
The nXDS pump is an environmentally-friendly oil-free vacuum pump that has no lubricants in the vacuum.
The scroll design and tip-seal technology mean the pumps have a longer lifetime compared to other products.
The company predicts that the tip seals may last up to five years.
They can be replaced in less than 10 minutes in the field using basic workshop tools.
Control modes include serial, USB, remote parallel and analogue as well as manual operation with simple up / down buttons.
Full serial communications mode provides feedback about the state of the pump, enabling scientists to optimise their process and schedule routine maintenance conveniently.
It also assists with preventative maintenance regimes, as the nXDS pumps indicates when service is needed via a light indicator on the control panel.
nXDS has low acoustic noise of only 52dB(A) and is quiet in the laboratory - up to 20 times quieter than some comparable pumps.
Ithas a standby mode, which reduces power consumption and users can set speeds ranging from 66% to 100% of full speed.
As a result, users can save money associated with energy use, while also improving their carbon footprint.
The nXDS6i, nXDS10i, nXDS15i and nXDS20i have pumping speeds between 6 m3hr-1 and 20 m3hr-1 combined with class leading ultimate vacuum levels.
A gas ballast switch allows for applications involving water vapour to be easily managed.
It can be used in applications including beam lines and high energy physics, backing turbo molecular pumps, distillation, extraction and filtration, freeze drying, solvent recovery, rotary and centrifugal evaporators, sputtering, scanning electron microscopes and focused ion beams, general laboratory bench top and clean pumping.
