The Edwards “RV” (simply meaning Rotary Vane) laboratory sized oil sealed rotary vane vacuum pumps have been in the market since 1993. They have a very unique design with no equal. This article will attempt to show the reasons for its design and introduction and then explain the features of the vacuum pump that make it one of the best small vacuum pumps available today. This is not an official Edwards account, although the engineering related content is based on Edwards information, it contains my personal knowledge, experience and understanding from working with these pumps for many years.

Definitions – Vacuum Terms, Related Terminology
No matter what field you study, an accurate knowledge of its vocabulary is essential to understanding the subject. In the field of vacuum heat treatment, considerable emphasis is placed on the proper use, meaning, and interpretation of certain words or phrases. A brief summary of the terminology including common processes being run is presented below.
Annealing – Heating above the critical (Ac1) temperature and holding at a suitable temperature followed by cooling at a suitable (slow) rate for purposes such as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure (for subsequent operations), reducing internal stresses, or for obtaining desired mechanical, physical or other properties. Cooling is often performed in the furnace. Other common names and related subjects include black annealing, intermediate annealing, isothermal annealing, malleablizing, process annealing, quench annealing, recrystallization annealing, and spheroidizing.
