Thomas piston pumps utilize proprietary WOB-L® pump technology from Gardner Denver. WOB-L® piston pumps can provide higher pressure and flow capabilities than many other pump technologies, in a much smaller package. They cover a wide range of applications due to the breadth of product platforms and performance capability.

Flow rates range from 5.4 l/min (0.19 cfm) to 212.4 l/min (7.5 cfm). The pneumatic performance covers pressures up to 12 bar (175 psi) and vacuum levels up to -990 mbar (29.2 in.Hg). Various motor options address lifetime requirements.
