Welch Vacuum Products

The extensive Welch Vacuum product range includes:

  • Diaphragm Pumps and Systems Clean operation (oil free), low cost of ownership, highest reliability – these are just a few benefits that customers can appreciate when they use a diaphragm pump for laboratory or industrial applications. With a broad range of diaphragm pumps – ultimate vacuum from 75 – 1 mbar and peak flow rates up to 138 l/min – Welch offers specific pump families and models for a variety of uses.
  • Rotary Vane Pumps & Systems Welch’ direct driven rotary vane pumps are well known for their high vapor tolerance, which leads to an outstanding reliability for chemical applications.
  • Oil-Free Dry Vacuum Pumps ChemStar® Dry was developed for laboratory operations which require high pumping speed and deep vacuum, such as vacuum manifolds (Schlenk line), freeze dryer, vacuum oven and glove boxes. The system combines a proprietary vacuum blower with patented PTFE diaphragm technology to pump quickly down (150 l/min) to the working range for most evaporative operations (2.0 to 0.1 mbar) with an ultimate pressure of 10-2
  • WOB-L Piston Pumps WOB-L® piston pumps are reliable dry vacuum/pressure pumps for physical and aqueous vapor applications, where corrosion resistance is not required (not recommended for pumping acidic, basic, or organic fumes).
  • Turbo Molecular Pumps Turbomolecular pumps from Welch are used to generate a high and ultra-high vacuum up to a pressure range of 1×10 (at -10) mbar with an extreme high pumping speed.
  • Oil Diffusion Pumps & Systems Oil diffusion pumps from Welch are used to generate a high and ultra-high vacuum up to a pressure range of 5×10-7mbar with an extremely high pumping speed. Besides single pumps, Welch also offers complete oil diffusion pump systems.
  • Aspiration Systems Compact and portable aspiration/filtration systems with an integrated superior chemical resistant diaphragm pump are used for the safe and precise aspiration of non-flammable chemical, biological and med­ical liquids. They provide a safe transfer of liquid in all sectors of industry and in the laboratory.
  • Gauges and Controllers The total range of scientifically useful vacuums extends from approx. 1000 mbar (atmospheric pressure) down to 10-12 mbar – the ultra-high vacuum range. A physical measurement of the whole vacuum/pressure range is not necessary. Particular sensors and gauges must be used for parts of the whole range – rough, high and ultra-high vacuum. These systems are also offered in combination as multi-range vacuum gauges for covering multiple measuring ranges.
  • Vacuum Networks Netvac+ provides a flexible vacuum for your multi-user laboratory, enabling a precise vacuum readily available for all the users and applications in your lab – all from a single netvac+ installation.
  • Vacuum Pump Oil Use Welch vacuum pump oils to reduce oil change cycles and maximize performance. To cover the whole range of vacuum applications Welch offers several types of oil with different specifications.
