Our Vacuum Pump Repair Process -

Our Vacuum Pump Repair Process -

All of our vacuum pump technicians follow strict guidelines when servicing our customers' vacuum pump equipment. The procedures outlined below not only ensure a quality rebuild, but customer satisfaction as well.

  • Evaluation
  • Customer Review
  • Vacuum Pump Rebuild
  • Testing
  • Shipping
  • Warranty

Once a vacuum pump enters an IVS facility, it is visually inspected and photographed for reference. A Work Order is then generated and entered into our computer database. The vacuum pump is moved into our tear down area and queued for complete disassembly and decontamination. The vacuum pump then receives a comprehensive visual and mechanical analysis to ensure conformity to OEM specifications. All components required to bring the pump back to OEM standards are listed on the Work Order.

The Work Order is reviewed by our Service Manager and a Service Analysis Form (SAF) is generated and sent to the customer for review. The SAF provides our customers with a detailed explanation, including the cause of failure, parts required, and cost breakdown to repair the unit. This gives our customers the opportunity to ask any questions they may have and allows IVS to make any necessary recommendations. One of our Customer Service Representatives will follow up with a phone call to discuss the status of your equipment and gain approval to start the overhaul process.

Once customer approval is given, the Service Manager will issue an overhaul kit and any other components required for the rebuild, and assign the job to one of our technicians. The overhaul kit includes all consumable items, such as seals, gaskets, o-rings, bearings, valves, etc. Turbomolecular kits include ceramic bearings, o-rings, and vibrations rings. The technician is responsible for the cleaning and the re-assembly of the pump..

The completed vacuum pump is then moved to our test station and put through a series of industry proven tests. These tests include base pressure, ballast pressure, and load testing. Turbomolecular pump testing includes a vibration analysis, speed analysis, and decibel readings, as well as load testing. This series of tests ensures our customers receive a quality product.

Once the vacuum pump passes all testing, it is prepped for return shipment to our customer. The oil is drained and the finish of the vacuum pump is restored to OEM colors and returned to your facility. Smaller pieces of equipment are properly foam packaged prior to shipment.

IVS prides itself as the industry leader. Our Business Practical Warranty on parts and workmanship from the documented date of installation, not shipment, gives our customers a comfort level when maintaining vacuum pumps in storage.

    Yes! In addition to servicing just about every make and model of vacuum pumps, we do sell new and reconditioned vacuum pumps as well.  IVS has an extensive inventory of vacuum pump equipment that we refurbish and sell with a full warranty for about half the price of a new pump.

  5. How frequently should I change the oil in my vacuum pumps?

    The answer to this question varies from pump manufacturer to pump manufacturer. However, the general consensus seems to be every 3 to 6 months. The lifespan of vacuum pump oil has more to do with the process it is exposed to than the length of time it is in the pump. Keeping clean oil in your vacuum pump is one of the easiest and most cost effective ways to prolong the longevity of your vacuum pump. We advise our customers to change their oil every 6 months at a minimum, sooner if the oil looks dirty, or vapor pressure increases. If the system the pump is connected to produces a dirty by-product, or particulate forming process, then you may need to change the oil more frequently to maintain the pump in optimal condition.  IVS offers a variety of oils, filters, greases, and other ancillary products to help support your equipment. Please reach out to one of our sales engineers for more information.

  6. How often should I have my vacuum pumps rebuilt?

    The length of service between rebuild cycles depends on several factors; the type of vacuum pump, the type of system it is being used on or “process gas exposure”, the amount of use, and whether proper preventive maintenance has been performed.  Most manufacturers suggest an overhaul service every 13000 to 15000 hours of operation.

  7. What does the IVS Business Practical Warranty" cover?

    Our industry leading “business practical warranty” covers the workmanship and the parts we use in the rebuilding process. Our warranty begins from the DOCUMENTED DATE OF INSTALLATION, not when the unit ships, like OEM’s and other third party pump rebuilders. When an IVS rebuilt pump is put online, our customer signs and dates a simple warranty activation form that is attached to the pump. The form is then sent to IVS so we can document the pumps activation in our computer database.  This type of warranty provides our customers a comfort level knowing that an IVS rebuild can sit in storage as a spare for an extended time period and not lose the warranty.

  8. What doesn't the IVS Warranty cover?

    Our warranty does not cover exposure to significant process contamination, such as heavy particulate, moisture, or caustic chemistry that may damage the pump.  Our warranty will also not cover the improper use or mistreatment of the unit.

  10. What vacuum fluid should I use in my pump?

    There are several different types of vacuum pump fluids available to lubricate and run vacuum pumps. The system application usually dictates the type of oil required. There are 3 main types of oil that are commonly used;  Perfluorinated Polyether (PFPE), Hydrocarbon, and Silicon based diffusion fluid.  Fomblin (Solvay) and Krytox (DuPont) are two brands of PFPE fluids.  This fluid is used when aggressive chemical environments or high concentrations of oxygen are present.  Standard industrial applications require hydrocarbon based fluids.  Diffusion pump fluid is a synthetic organo-silicon oxide polymer based oil that has exceptional chemical stability at high temperatures.  IVS offers our customers several choices of these oils with different viscosities and maintains them in stock.

  11. Why is there white smoke coming from the exhaust fitting?

    The “smoke” that is coming out of your pump is actually oil vapor mist.  It is normal for a small amount of oil vapor mist to come out of a pumps exhaust while the pump is pulling a chamber down to its ultimate vacuum. Most customers never see this happen as their pump exhaust may be piped out of building or they may have an exhaust mist eliminator attached to the pump.  The vapor mist should subside to almost nothing once the ultimate vacuum is achieved. If it does not, then there may be a vacuum leak at some point in the system or within the pump itself. The simplest explanation is air in, air out. Make sure all of the pump connections are clean and snug. If possible, blank off the pump inlet and see if the vapor mist subsides. This will eliminate the vacuum pump as the possible source of the problem.  If the problem persists, please contact one of our sales engineers for more information.
