Edwards has launched a new range of single stage oil sealed rotary vane pumps designed as a flexible vacuum solution to provide highly stable vacuum performance.
The optimised oil return system eliminates pressure fluctuations typically seen in single stage pumps improving product quality and giving consistent process results.
Designed for use in a wide range of industrial applications including heat treatment and coating, the ES rotary vane pump comes in a choice of five variants 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.
The pump mechanism on the new ES pump has been refined to produce a better quality of vacuum with the pumping speed 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 ES also has the added benefit of running more quietly than most comparable single stage rotary vane pumps.
Features also include in-built ISO and BSP connections for convenience and ease of integration. The ES pump is simple to maintain with easy oil and filter changes and can be serviced on site by the user, bringing higher productivity.
