Waterra Inertial Pumps: Low Flow System and Accessories
This pumping system is highly recommended for purging and sampling from 17 to 19mm ID piezometer tubes. The 13mm OD inertial pump tubing leaves sufficient annular space in the piezometer tubes to maintain a steady flow rate. In all but bery low yielding situtaions. It can be operated manually to approximately 30m achieving flow rates of up to 1.5 l/min.
