Edwards ES pump range the next generation of rotary vane pumps The Edwards ES range of pumps represents a significant advancement in single stage oil sealed rotary vane pumps. Enhanced performance – class leading ultimate vacuum level and extended operating pressure range • A wider range of industrial applications with good water vapour handling • Low cost of ownership - runs cool giving a long oil life time • Environment friendly - minimal oil emission • Quieter - than most comparable single stage rotary vane pumps Stability – stable vacuum performance, with no pressure fluctuations • Improved...

Edwards ES range is available in five variants from ES65 to ES630

Refined internal mechanism The improved pump mechanism is designed with attention to detail that guarantees a class leading ultimate vacuum level without the pressure fluctuations that are often seen in single stage pumps. Oil mist filter The improved integrated exhaust mist filter is very effective in preventing oil mist from being exhausted into the laboratory. It is user serviceable and gives the pump a much cleaner and quieter operation. This effective oil mist filter along with an improved oil baffle reduces oil loss to almost zero. Air cooling The pump is provided with an efficient air...

ES pump accessories There are a range of accessories available for easy control of the pump Oil level switch For remote monitoring of the oil level, to prevent potential damage to the pump. Available separately or in combination with a PT100 or a 120˚C sensor. Temperature sensors PT100 and the 120˚C temperature sensor to monitor temperature of the oil. Inlet Filter/Inlet Catch pots Inlet filters can be used to maximise uptime by preventing debris getting into the pump mechanism. Inlet Catch pots protect the pump from a large volume of condensable vapours.
