Used EDWARDS E2M28 #9233927 for sale

EDWARDS E2M28 is a portable, multi-purpose industrial vacuum pump specifically designed for vacuum-based pumping applications in a wide variety of industries and processes. It utilizes a Roots-type, positive displacement, rotary-lobe mechanism to evacuate gas from process vessels and other enclosed chambers. This mechanism operates by drawing gas in from the inlet port and trapping it in the lobe cavity. The trapped gas is compressed by action of the rotating lobes, forcing it out through the outlet port. EDWARDS E 2 M 28's robust design makes it particularly well-suited for the often challenging industrial environments. Its vacuum pumping capacity can be fully adjusted through a handwheel located on the front panel, allowing users to reduce or increase the flow rate to achieve the desired vacuum. The mechanical seals for both the inlet and outlet ports have been designed to withstand the high-temperature, corrosive gases often encountered in applications. E2M28 is built to withstand the demands of extended operation and is engineered to reduce noise levels. The internals are constructed from a variety of materials, such as stainless steel, corrosion-resistant aluminum, and oil-proofed phenolic resin, to ensure long-term endurance. Additionally, the vacuum pump's oil reservoir is engineered to keep oil mist levels low, providing quieter operation, and an oil mist detector is included as a standard feature. E 2 M 28's efficient design helps reduce downtime and maintenance costs, ensuring smooth and reliable operation. In terms of safety features, EDWARDS E2M28 includes a high-temperature safety switch which will shut off the motor if temperature levels exceed 230˚F (110˚C). This vacuum pump also includes a pressure switch which will shut off the motor when pressure within the chamber exceeds 489.6 psig (34 bara). A pump motor overload protection system is also included, which will shut off the motor if its current draw exceeds the rated draw of 9.5A. Furthermore, EDWARDS E 2 M 28 meets international safety requirements, making it suitable for use in hazardous locations. E2M28 is the go-to pump for high-capacity, vacuum-based processes that require portability, reliability and safety. Its heavy-duty, efficient design makes it the preferred choice for a wide range of industrial applications.
