WOB-L 2511® Piston Pumps
Brand: Welch VacuumWOB-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).
Each WOB-L® piston pump includes vacuum regulators, pressure regulators (single head models only) and gauges for simple adjusting and monitoring of vacuum level and delivery pressure.
To protect the pump from the ingestion of water, an inlet water trap with a float ball rises to seal the pump if needed.
A muffler ensures a very low sound level during pump operation, which makes the daily work with WOB-L more comfortable.
