Fully Refurbished Edwards E2M8 Dual Stage Rotary Vane Vacuum Pump, Hydrocarbon Oil, Elite Z, 220V
Edwards E2M8 Overview:
Fully Refurbished Edwards E2M8 Dual Stage Rotary Vane Vacuum pump. This pump has been thoroughly examined and is ready for a broad range of applications within the research and industrial industries.
The Edwards E2M8 pumps are oil-sealed and designed for reliable, long-term operation in both laboratory and industrial environments. The pumps are free-standind units. The drive is provided through a flexible coupling by a single-phase or three-phase motor.
The motors are totally enclosed and are cooled by the motor-cooling fan which directs air along the motor fins.
The single-phase motors have either an automatic or manual reset thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. If the thermal overload device has an automatic reset, when the pump cools down, the device resets and the pump will restart.
Edwards E2M8 Applications:
- Gas analysis
- Leak detection
- Mass spectrometers
- Electron microscopes
- Surface analysis
- CentrifugesSterilization
- DistillationMetallurgy
- Dry etching
- Load-lock
- Cryogenics
- Gas recovery
- Oxygen pumping
Edwards E2M8 Technology:
A rotary vane pump can be described as a positive-displacement pump that is comprised of vanes mounted to a rotor that rotates inside of an enclosure. In some instances these vanes can be of varying length and tensioned to maintain contact with the walls as the pump rotates.
The simplest rotary vane pump is a circular rotor revolving inside of a larger round enclosure. The centers of these two bands are offset, inducing eccentricity. Vanes are allowed to slide in and out of the rotor and seal on all edges, making vane chambers that do the pumping work. On the intake side of the pump, the vane chambers are increasing in volume. These increasing volume vane chambers are filled with fluid forced in by the inlet pressure. Inlet pressure level is actually the pressure level from the system being pumped, frequently just the atmosphere. On the exhaust side of the pump, the vane chambers are decreasing in volume, forcing fluid out of the pump. The activity of the vane drives out the same volume of fluid with each rotation. Multistage rotary vane vacuum pumps can reach pressures levels as low as 103 mbar (0.1 Pa).Visit the rotary vane pump wiki page for more information.

A & J Vacuum Services provides repair service for all types of High Vacuum equipment. We perform Turbomolecular Pump repair, Turbo Pump Repair, Dry Pump repair, Vacuum Pump repair, Mass Spectrometer repair, Rotary Vane Pump repair, Vacuum Booster repair, and Leak detector repair. Our highly trained technicians have years of experience and guarantee the highest quality service.
We operate at our own full service repair facility in Clifton, NJ. We have invested in state-of-the-art equipment including; complete line of decontamination, cleaning, drying, balancing, vibration analysis and software to minimize failures. Our in-house machine shop is capable of machining various components, prototypes and housing conversions as needed.
We support all major manufacturers including Pfeiffer Vacuum, Alcatel / Adixen, Edwards Vacuum, Varian, Oerlikon / Leybod Vacuum, Vacuubrand, and Agilent Technologies.
Repair Steps
- Full incoming inspection and run up time check, vibration check, drive inspection.
- Full disassembly, decontamination and cleaning.
- Pump is balanced utilizing state-of-the-art equipment from the world leader in equipment balancing and analysis to reduce noise and vibrations and extend bearings life.
- Assembly and replacement of all necessary parts such as shafts, bushings, bearings, sleeves, O-rings, gaskets, seals, wicks, etc. Only parts that meet or surpass OEM specifications are used to ensure dependable highest quality service and long pump life.
- Final test and leak check. The pump in fully assembled condition is checked for vacuum seal. Leak test to 1 x 10-9 Mbar l/s. Vibrations are analyzed and test data is digitally recorded.
Every pump and instrument is extensively tested for 48 hours. During our final tests, we monitor total pressure, temperature, vibration and noise level utilizing newest testing technologies and techniques specified by OEM. Upon request, we can provide our customers with a pump down graph. Call us for your free repair estimate at 1-973-249-0854.
