Does DOVAC also supply original spare parts?
Yes. DOVAC holds a large stock of original spare parts and original oil for a wide range of vacuum pumps and blowers.
- Perfect fit and retention of the original performance
- Maximum operational reliability and a longer service life
- Less risk of failure than with imitation parts
- How often does a vacuum pump need maintenance?
"
This depends on the type of installation, the number of running hours and the application.
- We advise having the installation inspected periodically
- Maintenance is then scheduled in good time, at a moment that disrupts your production process as little as possible
"
- Can maintenance be carried out on site?
"
Yes. Depending on the installation we carry out maintenance on site or in our own workshop.

- Does DOVAC also carry out repairs and overhauls?
"
Yes. In addition to preventive maintenance we provide:
- inspections
- repairs
- complete overhauls of industrial vacuum pumps and blowers
"
- How do I know that my vacuum pump or blower needs maintenance?
"
Wear develops gradually and is often not immediately visible. Watch for these signs:
- increasing energy consumption
- lower vacuum or air output
- unusual noise or more vibration
- higher operating temperature
- oil leakage or contaminated filters
- longer start-up time or fluctuating performance
Do you recognise one or more of these signs? Have the installation inspected before small deviations turn into major consequences.

- What is the difference between inspection, maintenance, repair and overhaul?
"
| Type | Purpose |
|---|
| Inspection | Assess condition and detect wear at an early stage |
| Preventive maintenance | Check or replace filters, oil and wear parts to prevent failure |
| Repair | Restore only what is needed after a defect or breakdown |
| Overhaul | Full inspection and replacement of worn parts after intensive use |
"
- What happens during a DOVAC maintenance service?
"
Our service engineers follow a fixed procedure:
- visual inspection and safe shutdown
- disassembly, cleaning and inspection of the filters
- oil change where necessary
- check of bearings, seals and rotating parts
- fitting of original spare parts
- ultimate pressure check and performance test
- test run, final check and reporting
The installation is only released for use once all measurements are in order.
"
- Does DOVAC also service pumps of other brands?
"
Yes. Our service engineers service and overhaul installations from a wide range of manufacturers every day:
- oil-lubricated and dry vacuum pumps
- liquid ring pumps
- side channel blowers
- turbo blowers
"
- May I use a different oil myself?
"
We recommend using original oil to the factory specification only. Oil does more than lubricate:
- cooling
- sealing
- protection against wear
- removal of contamination
The food industry adds a separate requirement: a food grade or approved mineral oil, so that a drop of oil or oil mist in the surroundings is not a risk.
