They are used in composite moldings, flight instruments have them, CRT’s are embedded with them, mass spectrometers contain them, analyzers can’t do without them; whether its distillation or drying, transfer of hazardous waste materials or lyophilization- they are everywhere. All the above-mentioned processes depend heavily on none other than the vacuum pump. If the process has to work, then the pump has to perform, without it all goes down. Such is the importance of these pumps in crucial settings like laboratories and hospitals.

If maintained well, unexpected pump failures can be prevented, and reliable service can be expected from the pump for years to come. The value of having a preventative maintenance program cannot be overemphasized.

Certain Basic Steps Need To Be Followed To Maintain And To Conduct Vacuum Pump Servicing

  • Maintain a good record: A simple checklist of routine maintenance jobs can take place. In most cases, the manufacturing company provides such a chart. Another log can be maintained to document the details such as routine maintenance, replacement of any parts, and repairs. This will help in finding out future problems. Also, it is advisable to keep a track of the number of hours the pump has been running in between service tasks. Other points to log in the chart would be the vacuum level before and after each cycle, pump downtimes and maximum level of vacuum achieved. This is purely a preventative step but is a life saver when it comes to servicing the pump, as this data is extremely crucial.
  • Timely oil changes: There are various sources of oil contamination which result in damage to the pump and malfunctioning. Periodic oil changes should be performed as outlined by the manufacturing company. This can be easily done by anyone even without much technical knowhow. Oil leakages are also common with several types of pumps, thereby calling for periodic level inspection as vacuum pump servicing.
  • Inspection of drive belts and couplings: Cracked or polished drive belts should be replaced without any delay. Drive belt tension should also be checked preferably using a gauge or by manually pressing the belt to see if it goes down by half an inch. Pressure adjustment will be needed in such a case. Certain pumps use a coupler which should be checked for cracks, looseness, and misalignment.
  • Visceral cleaning and inspection: It is recommended to dismantle the pump and inspect it after every 3000 hours of operation. Where applicable, vanes should be replaced together, interior surfaces should be cleaned thoroughly using acetone and isopropyl alcohol, and other spare parts including rotors should be checked and replaced if needed. Such a thorough job maybe done by a regular serviceman, another service provider or the manufacturing company can be consulted.

While the above-mentioned tasks seem too much work as vacuum pump servicing, it is well worth the effort. Vacuum pumps servicing is surely not inexpensive, and every buyer would want value for money in terms of the durability and functionality of these pumps. Preventive maintenance can be done in-house with a certain amount of training including certain jobs as oil checks and changes.
