Edwards, Dual Stage, Rotary Vane Vacuum Pumps

To meet your demands for high throughputs with high ultimate vacuum BOC Edwards have developed a totally new concept in vacuum pumps - the world's first dual-mode vacuum pump.

This radical operation is matched by innovative design features such as a pumping mechanism incorporating advanced new materials, a fully-featured BOC Edwards motor and the incorporation of a fast-acting inlet valve to seal the pump for suck-back protection.

In addition, BOC Edwards extensive research into drive train and motor noise mean the RV series also delivers a high performance pump with a broad performance envelope that's quiet to live with and easy to maintain. – noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor.

The pumps have the unique ability to deliver excellent ultimate vacuum in both high vacuum and high throughput modes with or without gas ballast. This gives the user an unrivaled opportunity to select the optimum pumping performance without compromising the application.

In its high vacuum mode, the RV pump is ideal for analytical instruments, electron microscopes, physics research. Configure the same pump in the high throughput mode, and it becomes suitable for mass spectrometer inlet systems, distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze drying and other drying applications.

The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running.

为了满足您对具有高极限真空度的高产量的需求，BOC Edwards开发了一种全新的真空泵概念 - 世界上一台双模真空泵。

这种激进的操作与创新的设计特点相匹配，例如采用*新材料的泵送机构，功能齐全的BOC Edwards电机以及快速作用的进气阀，以密封泵的回吸保护。

此外，BOC Edwards对传动系统和电机噪音的广泛研究意味着RV系列还提供了一个高性能的泵，具有广泛的性能范围，安静，易于维护。 - 48 dBA 50Hz的噪音水平通常是传统泵的噪音的一半，并且通过对传动系和电机的大量工作实现。

这些泵具有*的能力，可在高真空和高通量模式下提供出色的极限真空，有或没有气镇。这为用户提供了的机会，可以在不影响应用的情况下选择蕞佳泵送性能。

在高真空模式下，RV泵是分析仪器，电子显微镜，物理研究的理想选择。在高通量模式下配置相同的泵，它适用于质谱仪进口系统，蒸馏，实验室炉，背衬蒸汽泵，溶剂浓缩，冷冻干燥和其他干燥应用。

简单易用的模式选择器和可触及的三位气镇控制装置可以随时重新配置泵，即使在泵运行时也是如此。
