Single Point Packer: Installation & Inflation
Model 800 Pneumatic Packers are inflated with air via 1/8" (3.2 mm) O.D. tubing extending from the packer to the surface. A manual hand pump with a gauge may be used to inflate the packer. Please read through these instructions fully before proceeding.
Note:
|
Figures A and B illustrate centralizer installation for both Single Point and Straddle Packers. For packer specifications, borehole sizes and required inflation pressures, please refer to the charts below.
|
- Cut an appropriate length of 1/8" (3.2 mm) O.D. tubing to extend from the packer to the surface. This tubing must extend to the surface with enough slack to allow ease of inflation.
- Push the inflation valve onto the top end of the tubing and connect the other end of the inflation tube to the packer.
- For proper connection of tubing to compression fittings, simply push the tubing into the fittings until it “bottoms” and tighten the nut 3/4 turn past finger tight. Check the connection by pulling firmly on the tubing. It should not pull out of the fitting.
- A safety cable should be attached to the eyebolt on the packer to allow securing at surface. The Solinst Tag Line can be used for this purpose. (See Model 103 Data Sheet.)
- The system is now complete and should be installed by connecting the appropriate riser pipe and lowering the system into the well. Hang the riser pipe such that the packer is suspended at the appropriate depth.

| Inflation Pressure |
35 - 40 psi, 240 - 275 kPa |
25 - 35 psi, 170 - 240 kPa |
Notes:
- Inflation pressures must be added to hydrostatic pressure at the packer location.
- Maximum depth from surface = 275 ft (84 m)
- Maximum submergence = 150 ft (46 m)
- Maximum pressure for any packer = 50 psi or 345 kPa over hydrostatic
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 = 63psi. (46 mm packer: 140 kPa min +
(30 x 9.8 kPa) = 140 + 294 = 434 kPa)
