Edwards Edwards E2M80 57 CFM Dual-Stage High Capacity Vacuum Pump

Edwards E2M80 57 CFM Dual-Stage High Capacity Vacuum Pump Brand new Edwards E2M80 high capacity vacuum pump with one year manufacturer warranty from Edwards. https://shop.edwardsvacuum.com/products/a36504940/view.aspx Overview Edwards E2M 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.A comprehensive range of accessories is available to allow use on a wide variety of vacuum applications.Supplied with Ultragrade 70 Oil. Fomblin must be purchased separately for PFPE prepared pumps E2MFX. 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.An integral oil pump ensures that a more than adequate oil flow is pumped throughout the stator/rotor assembly at all times. 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 50-70 of the maximum. A full length, easily visible oil level sight glass allows you to conveniently monitor the oil level.Gas Ballast Facility: The EM pumps have a gas ballast valve. 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.Low Noise Levels: The EM pumps maintain Edwardss reputation for quiet operation pumps with a typical noise level of 70 dB(A).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 Thin film coating technologies Pharmaceutical freeze drying Refrigeration and air conditioning system evacuation, drying, and backfilling Transformer and cable drying and impregnation, insulating oil treatment plant Lamp manufacture Cryogenic vessel evacuation Vacuum drying and distillation in chemical industries Semiconductor device manufacture Backing pump for high vacuum applications

Welch Vacuum - Gardner Denver Welch ProBoost Air-Cooled Diffusion Pump

Welch ProBoost Air-Cooled Diffusion Pump Product Details Use Welch ProBoost in conjunction with a backing pump like the CRVpro to get deeper vacuum and higher flow. High Vacuum to 10⁻⁵ torr Use with high vacuum and Schlenk lines Employs air cooled diffusion pump Easy Attachment to backing pump Welch ProBoost is an air cooled gas jet pump (commonly called a diffusion pump). The gas jet is formed by directing boiling silicone vapors through a hollow cone. There are no internal moving parts. The pumping action commences when the vacuum pressure in the still (i.e. wiped film) goes below 0.2 torr (200 millitorr). On an empty, leak free still, ProBoost backed by a rotary vane pump lowers the vacuum pressure to 0.00002 torr (20x lower in pressure than a 2-stage rotary vane vacuum pump can do alone). ProBoost backed by a rotary vane vacuum pump will lower vacuum pressure to below 0.0001 torr in high vacuum and Schlenk lines. This high vacuum is invaluable to improve the results from reactions using air-sensitive compounds such as organometallics, metal amides, and hydrides. ProBoost has a built-in control board for fan and heater. When you turn on ProBoost, the fan and heater both turn on. When you turn off ProBoost, the heater turns off immediately and the fan runs for another 20 minutes to cool the pump.
