Description

WOB-L® 2522 dry piston pumps are a reliable partners for physical applications, notably with aqueous solutions. Being a vacuum pump and compressor, they can be used for a wide variety of applications such as filtration, gas sampling, vacuum drying, desiccation and automation technology. The integrated vacuum and pressure gauges and regulators allow the pressure to be continuously monitored and adjusted. The pump is protected by an inlet liquid trap with automatic flow stop.

For use with dry or aqueous vapor applications only.

Advantages: 

  • oil free
  • easy to clean
  • easy maintenance
  • easy handling and control features
  • robust construction
