| Features
Equipped with sensors to protect your pump products: NES pumps are equipped with sensors to measure pump temperature, oil level and pressure in the tank. Also equipped with PTC motor thermistor for motor and overcurrent protection.
The internal mechanism is specially designed for low temperature environments: to ensure that you get a satisfactory ultimate vacuum level without pressure fluctuations. The design of the mechanism ensures that there are very few hot spots in the pump.
is very suitable for various applications: if your application environment is explosive, the NES pump is your ideal choice. The pump is suitable for the chemical, pharmaceutical, degassing, automotive and gas vapor recovery industries. Edwards application team can help you determine the ideal use of the nES pump in your application.
with ATEX compatible accessories: ATEX rated exhaust oil mist filter, FPM seal, oil filter bypass, ATEX rated motor and coupling, approved oil, air bag unit
| UseIn industry: vacuum degassing and drying, heat treatment and vacuum oven, vacuum insulation, plasma treatment (except O2 plasma)
in gas detection and treatment: leak testing, gas production and treatment
in scientific research: research and development, support of high vacuum pumps or systems
