Pumping Rate, Well Development and In-line Filters

Optimize the Pumping Rate

For the most efficient operation, the following points should be considered when operating the 404 Inertial Sampling Pump:


Well Development

The Inertial Pump can be an excellent well development tool. A minimum annular space between the footvalve and the well casing, can create a strong churning effect that helps remove silt and fine sand, to enhance well development. Turbidity is greatly reduced after well development.

Pumping silty water is possible, however, should the silt settle and clog the footvalve, it may be cleared by unscrewing the footvalve from the tubing and tapping the footvalve and tubing to dislodge the sediment.


In-line Disposable Filters

In-line Disposable Filters are easily connected to the riser tubing using the 3/8" (9.5 mm) hose barb inlet. Simply press fit the inlet into the tubing and operate the pump as usual. The outlet connector is also a 3/8" (9.5 mm) hose barb. There is also a 1/8" NPTM vent/drain connection. The operating pressure of the pump is sufficient to filter the sample.
