How can we help you?
Oil-free vacuum pumps are the future of every lab and industrial work environment. These environmentally friendly products bring a range of benefits, such as clearer samples, cleaner workspace and reduced maintenance. We offer products from three positive displacement oil less pump technologies: Diaphragm pumps, WOB-L® piston pumps and a proprietary vacuum system.
Welch WOB-L Piston pumps are standard duty dry vacuum pumps for general usage. They provide moderate vacuum/pressure in a wide flow range for with vacuum reaching up to 5 Torr.
Because the pumps are oil-free, there is no oil contamination of samples, no exhaust smoke, no oil leaks, and best of all, no oil changes.
That means no oil maintenance and disposal, clearer work spaces and cleaner samples. Ultimately these pumps are also more sustainable and safer for the environment.
Welch Oil-less vacuum pumps stands to the promise of robust and reliable products for vacuum applications starting from Cell culture media sterile filtering/aspiration, DNA/RNA/Plasmid extraction, vacuum ovens, vacuum filtering, vacuum bag parts forming, sampling, pick and place, package integrity testing, turbidity testing, air sampling up to many other laboratory and industrial ones.
Welch provides state-of-the-art oil-free vacuum pumps for numerous applications in life science lab applications, as well as for a variety of industrial market needs, such as high vacuum manufacturing, freeze drying, glove boxes or ultracentrifuges.
In addition to our state-of-the-art products we have a proven reputation of providing prompt and our exceptional services. They include engineering assistance, service, valuable training, and efficient technical support.
Thanks to our in-house laboratories we ensure that our vacuum pumps meet all our customers’ requirements – both now and in the future.
Our Diaphragm Pumps offer vacuum up to 0.75 Torr and a great chemical resistance. We offer a dedicated lines of chemical resistance diaphragm pumps as well as diaphragm pumps with explosion proof motors.
Because the pumps are oil-free, there is no oil contamination of samples, no exhaust smoke, no oil leaks, and best of all, no oil changes.
That means no oil maintenance and disposal, clearer work spaces and cleaner samples. Ultimately these pumps are also more sustainable and safer for the environment.
