800 Low Pressure Pneumatic Packers are a low cost option, which makes them ideal for short-term applications. These packers fit perfectly in 2” and 4” (50 mm and 100 mm) monitoring wells, and they are also suitable for use in smooth boreholes with inner diameters between 1.9” - 5” (48 mm - 127 mm). The packers are inflated with a hand pump with the inflation pressures recommended varying by packer size. For the 1.8” (46 mm) packers, inflation pressures range from 20 psi - 40 psi (140 kPa - 275 kPa) above hydrostatic pressure. Pressures of 20 psi - 30 psi (140 kPa - 240 kPa) above hydrostatic pressure are recommended for the inflation of 3.7” (94 mm) packers.
These low-pressure packers utilise glands made from black-carbon-reinforced rubber (BCR) that are fitted on a body of Sch 80 PVC. In most cases they are lowered through either flexible tubing made from low-density polyethylene or a PVC drop pipe. When packers are lowered without the aid of a drop pipe safety lines should be attached to the eyebolt provided.
Solinst Model 103 Tag Line is perfect for Model 800 Low Pressure Pneumatic Packers. Model 103 Tag Line is a strong cable that is capable of lowering packers effectively while measuring placement depth. When using nylon compression fittings on each individual packer, an inflation line of 1/8” (3 mm) low-density polyethylene can be attached with minimal effort.
Model 800 Low Pressure Pneumatic Packers work best with Solinst Double Valve Pumps and Solinst Integra™ Bladder Pumps. It is easy to attach these pumps above the packers, and the water inlet can be located below a single packer or placed between straddle packers with a perforated pipe. It is also possible to suspend Solinst Leveloggers below or between packers from their eyebolts for hydraulic conductivity testing.
