WOB-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.
WOB-L® piston pumps are characterised by their simple rugged design and non-sudden failure mechanism (unlike many alternative technologies). Seal and comprehensive service kits are available.
Due to its lightweight and compact design WOB-L® can be used as a portable vacuum/pressure system on laboratory applications. WOB-L® piston pumps come with a dial gauge, a pressure regulation valve, an inlet condensate collection jar, a noise reduction muffler, and suction feet for counter-top stability.
Please note that only selected models can be used as pressure pumps.
Applications: Physical applications, Vacuum oven, Industrial, Desiccation, Filtration, Gas sampling, Glove boxes, Automation
