Low Pressure Packers

Pneumatic Packers are used to isolate a discrete zone in a well or borehole to prevent the mixing of soil gas or groundwater at that particular depth. Subsurface investigations are then focused on the isolated zone only. At the desired depths, Packers are inflated to seal off the discrete zone. This can be done using a single Packer, to monitor the zone above or below it, or a straddle Packer set up to create an isolated section between two Packers.

Solinst Low Pressure Pneumatic Packers are available in two diameters, as single or straddle packers primarily for use in 2" to 5" monitoring wells (50 and 125 mm). They can be inflated using a hand pump to a maximum of up to 50 psi (345 kPa). Solinst Packers are designed to temporary, low-pressure applications to monitor soil gas and groundwater.
