Single or Straddle Packers
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.

Notes:
-
Inflation pressures must be added to hydrostatic pressure at the packer location.
-
Maximum submergence = 150 ft (46 m)
-
Maximum pressure for 1.8" (46 mm) packer, = 50 psi or 345 kPa
above hydrostatic pressure. Maximum pressure for 3.7" (94 mm)
packers = 30 psi or 205 kPa above hydrostatic pressure.
eg: Required pressure for: Packer placed 100 ft (30 m) below water
• 1.8" packer in 2" well:
20 psi min + (100 ft x 0.43 psi) = 20 + 43 = 63 psi.
(46 mm packer: 140 kPa min + (30 x 9.8 kPa) = 140 + 294 = 434 kPa)
-
1 ft water = 0.43 psi, 1 m water = 9.8 kPa
