Laboratory Vacuum Pump Buyers' Guide | Labcompare

Jul 12, 2012 ... Historically, most vacuum pumps used in laboratories were oil-sealed, rotary vane pumps. Familiar forms include belt-drive and direct-drive models. The oil in these pumps is used to lubricate and seal the pumps. Because of the oil seal, these pumps can typically reach vacuum pressures of 10–3...

Vacuum Pumps: Oil-free Alternatives | Lab Manager

Apr 7, 2009 ... Vacuum pumps used in laboratories can be classified into two main types—rotary vane pumps, sometimes referred to as oillubricated pumps, and dry (oil-free) pumps. They operate in different ways to create vacuum and aspirate fluids. Centrifugal pumps use centrifugal force to push the fluid through an...

Improving Laboratory Vacuum Performance - Terra Universal

Note in the diagram above how the rotor is offset in the chamber, or “stator”. The rotor is set with only 1/1000” clearance from the top of the stator. Vacuum pump oil seals this tiny gap and prevents regurgitation of the airflow. For this reason this technology is referred to as. “oil seal, rotary vane” vacuum pumps. Vacuum pump.
