Simplicity is the key to the design of the WOB-L piston pumps. As the piston wobbles, air resistance on the upward stroke expands the PTFE seal on the piston to increase efficiency while compensating for the wobble action. WOB-L pumps set the industry standard for efficient vacuum utility. Use these pumps for reliable and affordable vacuum / pressure in applications where corrosion resistance is not required. WOB-L piston pumps come accessorised as standard including pressure and vacuum gauges & regulators, inlet catch pot and exhaust silencer. All pumps are supplied with a carrying handle for easy portability. Suitable for use with aqueous fumes including buffers. Not recommended for pumping acidic, basic, or organic fumes.
