These pumps, using no electrical components are useful if you have to sample in an intrinsically safe way. Stainless steel foot valves are re-usable as they can be cleaned in a dishwasher making them more cost effective than plastic valves which cannot be effectively cleaned, so could cause sample contamination if re-used.

  • Economical
  • Manual operation
  • Suitable for environmental analysis in groundwater wells with diameters from 9mm to 22mm
  • A simple and inexpensive groundwater research pump for well development and purging
  • Low risk of cross contamination as sample is not in contact with air

  • Light weight
  • Easy to install
