- With Single-phase motor
- Integrated gas ballast and HV safety valve
- For all low and medium vacuum applications
- With magnetic coupling
Pfeiffer DUO 5 MC Rotary Vane Pump, Single Phase, 95-120 V (50 Hz), 105-120 V (60 Hz), DUO5MC, PK D61 727D / PKD61727D
The Pfeiffer DuoLine Series of pumps are dual stage rotary vane pumps and are used primarily for rough and medium vacuum applications. The pumps are fitted with a hydraulically controlled vacuum safety valve which, when the pump is at a stillstand, closes the vacuum chamber vacuum tight and at the same time vents the pump. The integrated magnetic coupling functions free of contact and friction. Therefore it is not subjected to any mechanical wear and is completely maintenance free compared to a conventional shaft feedthrough.
Pfeiffer Duo Rotary Vane Pumps cover all applications in the low and medium vacuum range of up to 10-3 mbar. These pumps offer reliable operation even for such critical industrial applications as drying processes, metallurgical processes or resin potting and casting systems – either as a standalone pump or as a backing pump in roots pumping stations or turbo pumping stations.
The use of a magnetic coupling minimizes maintenance requirements and leads to considerable cost savings per pump and maintenance interval.
Reliable, clean, low maintenance. Compact design - Excellent performance data. Integrated safety and gas ballast valve. Contains no non-ferrous metals. Various motor voltages afford worldwide employment. M = Magnetically coupled

Service and Repair - Turbo Pumps
- Rotary Vane Pumps
- Dry Vacuum Pumps
- Leak Detectors
- Scroll Dry Pumps
- Vacuum Boosters
- Diaphragm Dry Pumps
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.
