The pump mechanism 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. The pump also has the added benefit of running more quietly than most comparable single stage rotary vane pumps. For convenience and ease of integration, the 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. These can be used individually or with the “EH” range of mechanical booster pumps to increase both performance and ultimate vacuum.
