Edwards’ new range of single stage oil sealed rotary vane pumps is a flexible vacuum solution providing stable vacuum performance. An optimised oil return system means that there are none of the pressure fluctuations that are often seen in single stage pumps improving product quality and giving consistent process results.
Edwards is launching the new ES range of pumps to the US market at the SVC (Society of Vacuum Coaters) 57th Annual Technical Conference May 3 – 8, 2014 in Chicago, IL. The pump mechanism on the new ES pump has been refined to produce a better quality of vacuum. The pumping speed is maintained even at lower pressure, extending the operating pressure range.
The ES pump has been developed to run cooler and have a longer oil lifetime than other comparable oil sealed vacuum pumps, bringing a low cost of ownership. The in-built oil mist filter ensures minimal oil emission, making the ES environmentally friendly. The ES also has the added benefit of running more quietly than most comparable single stage rotary vane pumps.
The new pump is designed to be used in a wide range of industrial and scientific applications, including coating applications, and those that require good water vapour handling. The ES can be used individually or with mechanical booster pumps to increase both performance and ultimate vacuum.
