New ES pumps provide highly stable vacuum performance
Edwards’ newly launched range of single stage oil sealed rotary vane pumps is a flexible vacuum solution providing highly stable vacuum performance. Thanks to the optimised oil return system, there are none of the pressure fluctuations that are often seen in single stage pumps, improving product quality and giving consistent process results.
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 new 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.
For convenience and ease of integration, the ES pump features in-built ISO and BSP connections; it is simple to maintain with easy oil and filter changes and it can be serviced on site by the user, bringing higher productivity.
The new ES pump is designed to be used in a wide range of industrial applications, including heat treatment and coating. There are five variants in the range to suit different requirements, ES65, ES100, ES200, ES300 and ES630. These can be used individually or with the EH range of mechanical booster pumps (variants available from EH250 to EH4200) to increase both performance and ultimate vacuum.
Megha Ajmal, Product Manager at Edwards, commented: 'We are proud to be introducing the ES pump range which provides class-leading ultimate vacuum levels. Suitable for a wide range of industrial applications and coupled with our robust EH mechanical boosters, it can provide customised solutions to a variety of processes.'
