How Does Rotary Vane Vacuum Pumps Work for Low-Pressure .

A vacuum pump refers to a device that is used to extract gas or air from a tank, creating a partial or complete vacuum. It involves sucking air in with gradual pressure decreased in a confined space, and the extracted gaseous molecules are released into another tank or the ambient air. Uses of Vacuum .

2020-5-26 · vacuum pump is designed to discharge to at-mospheric pressure or just slightly above unless the manufacturer specifically designates it as a compressor. As the discharge pressure of the pump increases above atmospheric pressure, this raises the differential pressure across the pump, resulting in: • Higher pump temperature and possible

Ultimate pressure and base pressure

If a pump is operated at ultimate pressure, the usable pumping speed will be zero, as only its own backflow losses will be displaced. Ultimate pressure is a theoretical value. Today, base pressure is specified instead of ultimate pressure. The conditions for achieving base pressure are specified in standard ISO 21360-1:2012.
