Edwards is previewing its Next turbomolecular pump range at Pittcon 2009, on booth 3085.
The Next pumps, which are used to create the vacuum systems for laboratory applications such as mass spectrometry and electron microscopy, have been designed to provide high vacuum performance in a compact size.
The range offers a wide variety of sizes and variants giving OEMs and end users the flexibility to tailor the most appropriate vacuum solution to meet individual needs.
The Next pumps are available in three sizes offering a choice of 240, 300 and 400 litre per second nitrogen pumping speeds.
Each is available in three variants: the S-Type is a simple turbo; the D-Type combines turbo and drag stages; and the T-Type adds Edwards' fluid dynamic stages and the option of additional booster ports for increased system rationalisation.
Custom interface split-flow variants are also available in three sizes for further vacuum system optimisation.
The pumps feature a field replaceable oil cartridge and bearing assembly and the user is notified as to when service intervention is required.
This enables Next pumps to be maintained easily as users can carry out servicing in-house.
The pumps have low power consumption and also feature a standby mode.
Next pumps have extra-low vibration and low magnetic field signature variants for sensitive electron microscope applications.
The compact design means the pumps fit together neatly in high product density applications.
They have an intelligent control interface accepting a 24 to 48V DC input power supply voltage range and can be controlled using a simple parallel control or serial communications in both RS232 or RS485 formats.
