    Welch-Ilmvac | WOB-L Piston Pumps

    Simplicity is the key to the design of the WOB-L piston. As the piston wobbles, air resistance on upward stroke expands the PTFE seal on the piston to increase efficiency while compensating for the wobble action. Reliable dry vacuum pumps and vacuum/pressure stations for physical and aqueous vapor applications.
