Model 800 Low Pressure Pneumatic Packers

These simple inexpensive packers inflate with a hand pump and are available in 1.8" and 3.9" (46 mm and 99 mm) diameters. Primarily for short term use in 2" and 4" (51 mm and 102 mm) monitoring wells, they can also be used in smooth boreholes and wells with 1.9 - 5" (48 - 127 mm) inside diameters. Typical inflation pressures for the 1.8" (46 mm) packers are from 20 - 40 psi (140 - 275 kPa) above hydrostatic pressure, and from 20 - 30 psi (140 - 205 kPa) for the 3.9" (99 mm) packers.

The Packers utilize a gland of black carbon reinforced rubber (BCR) on a Sch 80 PVC body. They are lowered on flexible low density polyethylene (LDPE) tubing or a rigid PVC drop pipe. If a rigid drop tube is not required for your application, it is recommended to attach a safety line to the eyebolt provided. The Solinst Model 103 Tag Line provides a convenient, graduated support cable that can be used for this purpose, as well as for measuring placement depth. The inflation line of 1/8" (3 mm) low density polyethylene (LDPE) is easily attached using the nylon compression fittings on each packer.
