Solinst - Model 800 -Low Pressure Pneumatic Packers
The 800 Low Pressure Packers are simple, inexpensive and inflate with a hand pump. They come as single or straddle packers and can be lowered into the well from a rope tether or a rigid PVC pipe. The 103 Tag Line can be used as a marked safety line. Available in sizes to fit wells and boreholes from 1.9" – 5" (48.3 – 127 mm) to a maximum pressure of 50 psi (345 kPa) for the smaller packer and 30 psi (205 kPa) for the larger packer. The 800M Mini Pneumatic Packer is also available to fit nominal 2" OD monitoring wells. It is lightweight and only 1ft in length. It is ideal for connecting to Solinst Pumps and for use during falling head and other aquifer tests.These simple inexpensive Solinst Low Pressure Pneumatic 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 a support cable 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 is standard LDPE tubing and connects to the Packers using a simple push fitting.
The 800M Mini Packers are 1 ft. (305 mm) in length and 1.8" (46 mm) in diameter, available in single or straddle packer setups. They are designed for falling head tests, and work easily with the Solinst Model 415 12V Pump to isolate groundwater sampling zones and reduce purge volumes in nominal 2" OD wells. They are also useful when multiple, shorter well intervals need to be isolated, e.g. during aquifer testing.
Isolating discrete zones for short term monitoring:
- Water sampling
- Hydraulic conductivity testing
- Datalogging with a Levelogger
- Minimizing purge volumes
- Reducing well development time
- Slug and pump tests
- Injection of tracers, amendments or other materials
- Air sparging (low pressure)
Solinst packers are ideal for use with Bladder Pumps or Double Valve Pumps, which can be easily attached above the packers. The water inlet can be below a single packer, or through perforated pipe fitted between straddle packers. For hydraulic conductivity testing, Solinst Leveloggers can also be suspended, either below or between packers, from the eyebolt on the bottom of the packer.
