P2.50 Groundwater pumps Groundwater pumps are usually applied for developing and purging monitoring wells before executing a sampling procedure. P2.51 Foot valve pumps for groundwater research Foot valve pumps are first of all intended for pumping groundwater that needs to be analyzed for purposes of environmental research.
Peristaltic pumps are also very useful for the in-line filtration of groundwater samples.
The filtration of groundwater during sampling is necessary in order to make future laboratory analysis possible, for such substances as heavy metals. Use can be made of a filter holder with exchangeable filters and of disposable filters.
