Two Stage Water Ring Vacuum Pumps are better design then Single Stage Vacuum Pumps, having advantages of higher capacity at high Vacuum and also requires low quantity of water at low pressure. It's design based on a latest technology and save energy. Two stage Vacuum Pump develops maximum Vacuum of 720mm of Hg, when sealing water temperature is 30ºC (755mm of Hg barometric Pr. & suction temperature 30ºC) and achieves vacuum up to 735mm of Hg, when sealing water temprature is 15ºC to 18ºC. Due to its latest technology and design, It so happen that a smaller model may require as compare to Single Stage Vacuum Pump.
