Used EDWARDS E1M18 #9113340 for sale

EDWARDS E1M18 is a liquid ring vacuum pump designed for industrial and laboratory applications. The pump utilizes two impellers to move gas and liquid, creating a vacuum on the suction side. E1M18 is capable of suctioning up to approximately 20 cubic feet per minute (CFM) of air flow, while maintaining a vacuum of 18 Torr or below. With a uniquely designed inverted pyramid dampener, the pump offers superior sound attenuation, as well as superior wear resistance. EDWARDS E1M18 features a two-stage operation, with both stages running at the same rotational speed. In the first stage, the rotors create a partial vacuum that increases the pressure differential between the inlet and suction sides. This pressure differential allows for the air and liquid to become internally recirculated and compressed within the chambers. The second stage then amplifies this expansion of the air and liquid mixture, creating a higher degree of vacuum. This process is frequently referred to as the "Vortex" effect. E1M18's construction features a durable, corrosion-resistant design, making it an ideal choice for industrial applications. It also includes four non-contacting, lubricated-for-life shaft seals, fluid ports, drain hole plug, inlet cove, fan cover, and fan guard. Additionally, the pump is equipped with an integrated oil bypass, which allows for quick oil changeout and extends the life of the pump. EDWARDS E1M18 is available in a variety of sizes ranging from 55 cm to 65 cm in diameter. Additionally, it is equipped with external motor support brackets that provide greater security and ensure proper installation. With a standard foot-mounted design, E1M18 offers easy installation and maintenance. EDWARDS E1M18 pump is a reliable, efficient choice for vacuum application in industrial and laboratory settings. It offers superior sound attenuation, a low maintenance design, a variety of sizes and superior performance.
