Used PFEIFFER / BALZERS TPU 240 #9250302 for sale

PFEIFFER / BALZERS TPU 240 is a dry-running mechanical pump designed for ultra-high vacuum applications. It utilizes a tubular housing with opposing axial pistons, which are reciprocated back and forth, compressing and exhausting the gas simultaneously. This eliminates mechanical seals resting on one side and the other, which is both more reliable and enables an exceptional ultimate vacuum level. The cylindrical housing is mounted independently allowing for optimal flexibility of setup and cavities in the housing enable the contact-less transfer of torque. Control of the rotational speed is achieved via an external frequency converter. Internally, BALZERS TPU 240 features a stainless steel second chamber structure which provides a further reduction of exhaust time. This second chamber also provides an additional shock absorber, deflecting impacts from external vibration. The axial pistons, made from carbon, are counterbalance to the motor rotor and feature tungsten carbide wetted surfaces. This minimizes friction loss as well as allowing for a long service life. The pistons are constantly monitored for pressure and current. In addition to this, PFEIFFER TPU 240 also features a self-regulating oil replenishment system that prevents cavitation during higher rotating speeds and reduces operating noise, making it both user friendly and energy efficient. Furthermore, the design of the pump is made for easy maintenance as the entire chamber is accessible through the lifting mechanism, resulting in lower system downtime and minimal maintenance cost. Overall, TPU 240 is an industry-standard pump specifically designed for Ultra-High Vacuum applications. Its low power consumption, high ultimate vacuum level, low noise, self-regulating lubrication system and its maintenance-friendly access make it an ideal solution for a wide range of applications.
