General Overview:
The EH pumps are compact and have high pumping speeds. You must use the EH pump with a suitable backing pump. The EH pumps can operate with a maximum continuous inlet pressure of 1000 mbar. You can achieve low system pressures by the use of two or more EH pumps in series.
The EH pump coupling-cover is connected to the pump outlet and forms an integral part of the vacuum system. The connecting lines have a filter which removes debris and so prevents contamination of the lubricating oil and bearings. For an even cleaner system, you can evacuate the coupling-cover and bearings by connection to the pump-inlet or to an external vacuum pump.
The hydrocarbon safe area and chemical EHpumps use hydrocarbon oils, such as Ultragrade 20. Versions of the safe area pumps for use with PFPE (perfluoropolyether) oils are also available for vacuum systems in which oxygen or other reactive or corrosive gases are pumped All the EH pumps have ISO inlet-flange and outlet-flange connections.
Unit is fully rebuilt and comes with a FULL 12-MONTH WARRANTY!

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.
