Solinst Model 800 Low Pressure Packers

Key Features

• Designed for isolating discrete zones for short-term monitoring
• Ideal for use with Solinst Bladder Pumps or Double Valve Pumps
• Inflated using a hand pump up to 50 psi

Overview
The Solinst Model 800 Low Pressure Packers inflate with a hand pump and are available in 1.8" and 3.9" (46 mm and 99 mm) 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.

Design
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. The inflation line is standard LDPE tubing and connects to the packers using a simple push fitting.

Applications
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. If a rigid drop tube is not required for the application, it is recommended that a safety line be attached 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.

Use
Solinst packers are ideal for use with Solinst 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.
