Used EDWARDS RV12 #9392883 for sale

EDWARDS RV12 mechanical vacuum pump is a two-stage, oil-sealed rotary vane pump. It is designed for applications requiring a low ultimate pressure and is well suited for transfer and backing the most sophisticated vacuum systems. It provides a working vacuum pressure of 1.0 x 10-5 Pa and is rated to 1.3 x 10-3 Pa and has a nominal pumping rate of 3.6 m3/hr. EDWARDS RV-12 has a single-phase, single speed motor with thermally protected against overloads. It has a motor speed of 1330 to 1450 rpm, and is capable of running in both vertical and horizontal configurations. RV 12 has a compact, lightweight design, making it suitable for portable, in-house, or laboratory-sized installations. RV12 utilizes a two-stage oil-sealed rotary vane design. The first stage has three vane slots around the rotor, while the second stage has four vane slots. This design offers superior ultimate vacuum performance compared to single stage pumps, while also improving pump life and oil consumption. As the efficiency of the pump increases, noise levels decrease as its noise envelope does not exceed 65dB. Additionally, oil vapor emission pump levels are minimized as the oil-seal lines are positively sealed for a much longer pump lifetime. EDWARDS RV 12 is equipped with a built-in anti-suckback valve, which prevents oil from backing up into the vacuum system when the pump is switched off. Additionally, the pump has built-in maintenance-free features including the EPA compliant oil-mist filters and an emptied oil container which can be easily accessed and replaced without the need for additional tools or equipment. RV-12 is an ideal choice for research, development and industrial applications. It is lightweight, reliable and energy efficient, and can be used for vacuum applications such as improved evacuation performance and heat transfer. Not only does it provide the benefits of an oil-sealed rotary vane pump, but it also is equipped with a variety of features such as oil-seal lines, anti-suckback valve and over temperature shut off to maximize its overall performance and reliability.
