Description

Product overview
WOB-L® 2522 dry piston pump. Item numbers 2522B-01, 2522C-02. The pump delivers oil-free vacuum and compression for laboratory and physical applications, notably compatible with aqueous solutions. Typical uses include filtration, gas sampling, vacuum drying, desiccation and automation technology. Integrated vacuum and pressure gauges and regulators allow continuous monitoring and adjustment. An inlet liquid trap with automatic flow stop protects the pump during operation with aqueous vapors. For use with dry or aqueous vapor applications only.

Advantages
  • oil-free operation (no contamination from lubricants)
  • easy to clean
  • simple maintenance
  • straightforward handling and integrated control features
  • integrated inlet liquid trap with automatic flow stop
