Used BOC EDWARDS EXT 255H #9203653 for sale

BOC EDWARDS EXT 255H is an oil-sealed heavy duty rotary pump designed for high vacuum applications. This pump is a single-head direct drive pump with an externally-lubricated motor to provide continuous operation. EXT 255H is designed to minimize oil carryover and non-condensable gas emissions. It is designed with a bearingless motor to reduce operational temperatures and minimize vibration and noise levels. This pump utilizes a PTFE rotating assembly to deliver fast pumping speeds for increased productivity and extended service life. The design also optimizes internal gas flows to reduce pulsation and enhance pumping efficiency. BOC EDWARDS EXT 255H is fine-tunable for ultimate flexibility in the field, using a variable speed motor to provide the exact vacuum and pumping speed requirements. This is also ideal for applications that require precise process control and in which changes in the process or in the environment must be taken into account. The variable speed feature enables the pump to maintain consistent process conditions and optimal performance. EXT 255H has an integrated oil lubrication system which allows for continuous oil circulation. This circulation reduces the formation of uneven wear on system components, enhances performance, and ensures that the bearings remain properly lubricated at all times. The purge function of the oil-sealed rotary vane pumps enables periodic cleanout to purge contaminants, air mixtures, and entrapped vapor from the system, while allowing the user to easily monitor oil levels. In terms of their environmental benefits, these pumps are also efficient in terms of energy usage and do not require any additional lubricants or mechanical accessories. BOC EDWARDS EXT 255H meets the highest quality standards and its design also ensures minimal downtime and maintenance. Furthermore, this pump can be fitted with custom accessories to further improve its performance and to meet specific customer requirements.
