Dry or non-lubricated vacuum pumps are gaining importance in application areas requiring low oil contamination is a critical factor. They offer clean vacuum over the entire vacuum range and require comparatively lesser maintenance than the wet or lubricated pumps.

Rotary Vane Vacuum Pumps, The Definitive Guide

Vacuum Pump Oil Contamination Risk The first disadvantage is the presence of low vapor pressure oil. The rotary vane vacuum pump cannot operate without the oil meaning that the oil has to be constantly watched, refilled, and replaced.

Vacuum Pumps: Basic operation and maintenance tips .

He explains that even a small piece of tape can damage the pump. Avoid contamination Solvents or hydrocarbons can damage vacuum pumps. If oil or solvent gets into the pumping chamber it will gum .

Oil Problems With Vacuum Pumps

HyVac vacuum pumps are all designed to run continuously. When tested at HyVac they are run for 5 days 24 hours per day prior to final testing and release to finished goods inventory. They, like most oil sealed rotary vane vacuum pumps are designed to pump air or gas, not necessarily liquids.

Vacuum Pumps: Oil-free Alternatives | Lab Manager

Oil-free diaphragm vacuum pumps can provide vacuum levels from atmosphere to below 0.5 mbar/torr, whereas oil-lubricated pumps offer high capacities and higher vacuum levels up to 10-3 mbar/torr. "What is more important is matching the vacuum to the application, and almost any application can now be performed using an oil-free pump, with the .

Vacuum Pump Oil Contamination - Tips & Prevention – Provac

Oil sealed pumps require oil to create a vacuum. Oil that is contaminated or which has thermally started breaking down needs to be replaced in order to maintain vacuum and keep the pump running properly. Proper maintenance can prevent the need to replace the pump altogether. Vacuum pump maintenance is a requirement for long-lasting equipment.
