Edwards nEXT930D - CF200 NW25 Turbomolecular Pump

Optidrive I55 gear pump

This Hanning Elektro-Werke Trivac Vacuum Pump Typ D8B was removed from a university lab where it was (more) surplus to requirements. The unit powers up and has been tested with a gauge (not included). It appears to be working well. The power cable is included. It is in good cosmetic condition with some marks from use.

VACUUBRAND MV 10C NT Chemistry Diaphragm Pump Ultimate Vacuum 0.9 mbar / 0.68 torr Maximum Pumping  (more)Speed 5.6 CFM at 60Hz Number of Heads/Stages 8/4 Features - Outstanding chemical resistance and superior vapor tolerance - Reduced process time due to very high flow rates even close to ultimate vacuum - Very low vibration and quiet - Excellent ultimate vacuum even with gas ballast - Excellent environmental friendliness due to efficient solvent recovery (on models with EK accessory) Four-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet the highest requirements. The four-stage design of the eight-cylinder pump MV 10C NT provides the advantageous combination of high pumping speed and very low ultimate vacuum of 0.9 mbar in a very compact design. All internal parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. Upgraded with an exhaust waste vapor condenser (EK) the MV 10C NT +EK provides an excellent, environmentally friendly system with efficient solvent recovery. A separator for the inlet (AK) made of glass (with protective coating) against particles and liquid droplets is available as an optional accessory. The high pumping speed and excellent ultimate vacuum of the MV 10C NT reduces the process time significantly. The pump meets the high vacuum requirements, e.g., of parallel processes in vacuum networks. Further typical applications are vacuum ovens, large rotary evaporators, pilot plants and mini plants as well as kilo laboratories. For rough operating conditions we recommend an inlet separator (AK) to protect the pump from particles and liquid droplets. The exhaust waste vapor condenser on the MV 10C NT +EK (also available as accessory) enables near-100-percent solvent recovery, efficient recycling, and active protection of the environment. INCLUDED: The VACUUBRAND MV 10C NT Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

Edwards mXDS3 Dry Scroll Pump Ultimate Pressure 0.1 mbar (0.075 Torr) Pumping Speed 2.06 CFM (3.5 m (more)^3/h^-1) Inlet Connection DN 16 ISO-KF (NW16) Features - Weighs in at just 17.2 lb. (7.8 kg) and comes with a purpose-made carry handle making it highly portable - Can typically be mounted horizontally or vertically and for convenient connection - Inlet can be orientated vertically or horizontally with a push-fit alternative available as an accessory - Delivers 2.06 CFM (3.5 m^3/h^-1) peak speed at 60Hz and 0.1 mbar ultimate pressure - Gas ballast facility incorporated in the design as standard for water vapour handling and an exhaust valve - Oil-free pump with no oil to top up, replace or dispose of - Optimized fan cooling is beneficial in reducing noise for quieter operation and a pleasant working environment - Low maintenance, with tip seal changes required over typically 2 years The Edwards Vacuum range of small dry scroll pumps is expanding with the introduction of the compact mXDS3 and mXDS3s Dry Scroll Pumps. The new mXDS3 dry scroll pump delivers 1.77 CFM (3 m^3/h^-1) pumping speed at 50Hz or 2.06 CFM (3.5 m^3/h^-1) together with an ultimate pressure of 0.1 mbar making it well suited for backing turbomolecular pumps. The mXDS3 is the standard option supplied with no inlet valve fitted, while the mXDS3s comes factory fitted with an inlet valve featuring delay opening. The mXDS3s is also supplied with an exhaust silencer. Both offer the same vacuum performance and feature an IEC connector for main supply and an on/off switch for easy control. This compact dry pump offers flexibility to the system designer and end user alike with a wide range of accessories available to choose from to meet your configuration requirements. This standard variant of the mXDS3 comes with a single phase 115V, 50/60Hz motor.
