Membrane Pump – Injection Pump

The membrane pump, applicable for gentle and depth-oriented sampling can be used for both, stationary and mobile groundwater sampling. It can also be utilized stationary, directly in the clogging zone of rivers.

The pneumatically operated injector pump can be used for the purification of groundwater observation wells.
