Introducing the New Edwards 28 E2M28 two-stage high-capacity Vacuum Pump.
Edwards E2M28 Technology
The motor of the Edwards 28 pump is totally enclosed and features a motor-cooling fan that directs air along the motor fins. The thermal overload device ensures that the motor doesn't overheat, switching off the pump when necessary. Once the motor has cooled down, the device resets and the motor restarts automatically. You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass, and an oil filler-plug is fitted to the top of the oil box. The pump has two oil drain-plugs to allow either gravity oil drain or pressure oil drain.
Included Accessories
Unbeatable value awaits you with the purchase of the Edwards 28 E2M28 pump. You'll receive Ultragrade 19 oil, NW25 O-ring and centering ring, and a lifting plate. Fomblin must be purchased separately for PFPE pumps.Â
Technical Support and Warranty
The Edwards E2M28Â comes with a one-year manufacturer warranty from Edwards to give you peace of mind. If you encounter any issues with the pump, simply contact their technical support team for assistance. You can be confident in your purchase knowing that you have the best vacuum pump and support in the industry. Please see packaging for Edwards technical support contact details.
