- What is the difference between an oil-lubricated and a dry-running vacuum pump?
"
An oil-lubricated vacuum pump uses oil for lubrication and sealing between the vanes and the pump housing. A dry-running vacuum pump works without oil in the pump chamber. Which version is suitable depends on the process, the desired vacuum level and the requirements for maintenance and possible oil contamination.
"
- Which oil should I use in my vacuum pump?
"
Use the oil that the manufacturer prescribes for your type of vacuum pump. The right oil depends on the pump and the operating conditions. In doubt? Send us the brand and type of your pump.
"
- How often should I replace the oil and filters of my vacuum pump?
"
That differs per pump type, use and operating conditions. We recommend having your vacuum pump serviced at least once a year. Dust, moisture or other contamination may make more frequent maintenance necessary. Also follow the manufacturer's maintenance instructions.
"
- What is a claw pump and what is it used for?
"
A claw pump is a dry-running vacuum pump. The pump compresses air with two claws that do not touch each other. As a result, no oil is needed in the compression chamber. Claw pumps are used, among other things, in industrial vacuum systems and production processes. Which pump is suitable depends on the required capacity and the desired vacuum level.
"
- What is a liquid ring vacuum pump?
"
A liquid ring vacuum pump uses a ring of liquid to draw in and compress gas. The pump is suitable for applications in which moist or wet gases are handled. The right version depends, among other things, on the gas, the process conditions and the desired vacuum level.
"
- When should I choose a liquid ring pump?
"
A liquid ring pump can be suitable when the process contains moist gases or vapours. Which version fits depends on the application and the process conditions. DOVAC is happy to advise you on a suitable pump.
"
- What is a central vacuum system?
"
A central vacuum system supplies vacuum from one central installation to multiple machines or workstations. Whether this suits your company depends, among other things, on the number of take-off points and the combined vacuum demand.
