With gas ballast. Contact Us. Overview Edwards E2M80 series two stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapour.
These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection. IE3 Energy efficiency 3 phase motors are now fitted to our standard motor pumps. This pump is suitable for most duties and is safe to handle non-flammable gases and vapours within the normal operating parameters of the pump. Technology Reliable system protection devices Every pump has protection devices to prevent oil and air suck-back into the vacuum system if the pump stops while under vacuum.
A variety of protection devices are used, depending on the pump size and cost, but emphasis is always placed on reliability and simplicity. When you use gas ballast on some of the pumps, you must use a solenoid operated gas ballast control valve to prevent air suck-back. Positive Pressure Oil Lubrication The EM pumps incorporate a well proven positive pressure oil lubrication system which as been developed by Edwards to ensure correct lubrication in all duty modes and particularly to prevent oil starvation with high gas loads.
This oil lubrication system means that the level of oil in the reservoir is less critical than with other pump designs. All pumps can operate with oil levels as low as of the maximum. A full length, easily visible oil level sight glass allows you to conveniently monitor the oil level. The valve is used to introduce a suitable gas into the stator during the compression stage: this prevents condensation of vapors inside the pump, dilutes and ejects corrosive gases and purges the oil of gases and vapors.
Therefore, the use of gas ballast reduces oil degradation and pump corrosion. Pumping Systems The EM pumps, with suitable accessories, can partner a variety of other types of pump in vacuum systems for industry and for research. A special feature of the E2M80 is the central vacuum inlet which enables you to fit a mechanical booster pump with a minimum overhang, to create compact combination pumping systems.
Easy Maintenance The advanced lubrication system allows the EM pumps to work with wide oil level tolerances, which reduce the need to top-up the oil. All EM pumps are constructed with internal dowels, which reduce the need for skilled setting of tolerances, when the pump is dismantled. The pumps are designed so that all key components are easily accessible.
The exhaust valve seals and oil distributor seals are exposed after the top cover is removed. The shaft seal can be replaced quickly without stripping down the pump. Applications Vacuum metallurgy processes. Features and Benefits Advanced pressurised oil circuit to give effective lubrication even under high gas loads. When the pump is switched off, the spring loaded distributor valve provides oil and air suck-back protection. Supplied with Ultragrade oil. List Price:.

Edwards Vacuum Pump E2M80 56.6 cfm NEW A36504940 230/460V 3PH
A four-pole three-phase motor provides direct-drive through a flexible coupling. The pumps are free standing mounted on steel runners. Lubrication is provided by a sliding vane oil pump. Oil is drawn into the pump through a wire mesh strainer. The oil is pumped to a spring-loaded distributor valve. The distributor valve directs a lightly-pressurised supply of oil to the main vacuum-pump and by-passes the excess back to the oil reservoir. Some of the excess oil is re-directed through a large area, fine-pore filter and some through a relief-valve.
