Page 6: Section 1: System Description
Section 1: System Description Function and Theory The PFAS Free Portable Bladder Pump is designed specifically for sampling per- and polyfluoroalkyl substances (PFAS) such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in groundwater. PFAS compounds are synthetic chemicals used in firefighting foams, stain resistant carpets, and other repellant/non-stick applications. -
Page 7: System Components
The pump assembly itself must be submerged below the water level. This means the depth to water cannot exceed the maximum pumping depth of the pump. If using a drop tube assembly not provided by Geotech, ensure all materials are PFAS testing approved. Use of unapproved materials... -
Page 8: Section 2: System Installation
Bladder Pump Controller 300PSI. Pump Tubing Lines The Geotech PFAS Free Portable Bladder Pump requires two tubing lines. One of the lines is used for the air supply and exhaust. The second line is used for discharge fluid. See Section 6: System Specifications for tubing sizes. -
Page 9: Reverse Coil Method
Reverse Coil Method When lowering the pump into the well, it is important to reverse the natural bend of the coiled tubing so that the tubing will straighten out as it is lowered (see figure 2-1). As the pump and tubing are lowered into the well, the direction of the bend should be reversed from the direction in which it is coiled. -
Page 10: Section 3: System Operation
Section 3: System Operation Once tubing and safety cable are connected, slowly deploy the pump into the well. If depth to water is known, a mark can be placed on the tubing to indicate when the pump has reached the desired level. The pump must be fully submerged. -
Page 11: Example Flow Rates
* Airline tubing size: .17”ID x ¼” OD (4 x 6 mm) Flow rates are based on 3’ (0.9 m) of pump submergence. Field environments typically provide over 10’ (3 m) of submergence, which increases flow. Speak with a Geotech representative to determine the best configuration to fulfill your sampling needs. -
Page 12: Selecting An Air Source
Selecting an Air Source The Geocontrol PRO is an easy-to-use portable compressor and logic unit specifically designed to operate Portable Bladder Pumps deployed down to 180’ (55 m) or less. Air consumption depends on the volume of tubing and the size of deployed Bladder Pump. Follow the general guidelines and examples below to calculate the air consumption for specific sampling configurations. - Page 13 Figure 3-1: Tank Volume vs. BP Consumption...
-
Page 14: Determining Psi
Determining PSI Determine the air pressure needed to operate the Bladder Pump based on the length of the air supply line to the pump (well depth). Use the simplified formula: 0.5 PSI (per foot) + 10 PSI (to account for tubing friction) = required PSI 0.12 bar (per meter) + 0.7 bar (to account for tubing friction) = required bar As mentioned above, the additional 10 PSI/ 0.7 bar is to account for the pump itself and friction loss along the airline tubing. -

Section 4: System Maintenance Geotech uses black Buna-N O-rings for the PFAS free portable bladder pumps. If you receive an O-ring from Geotech that is not black, do not use the O-ring on the bladder pump and contact a Geotech representative. - Page 16 Remove the lower Compression Ring by pulling it off the end of the internal center tube assembly. Figure 4-2: Removal of bottom Compression Ring Remove the upper Compression Ring by sliding it over the bladder and over the end of the internal center tube assembly. Figure 4-3: Removal of upper Compression Ring Pulling from the lower end of the bladder, slide the bladder off the internal center tube weldment assembly.
- Page 17 Remove all O-rings. If needed, use a flat object to help the O-ring out of the groove on the center tube weldment assembly, Do not over-stretch, damage, or puncture the O-rings in any way. Figure 4-5: Removal of O-rings Clean and prepare replacement parts as needed.

Page 22: Replacement Parts
Due to the sensitivity of PFAS testing, it is important to use only PFAS testing approved materials. Use of unapproved materials, such as Viton, will contaminate samples. Additional PFAS approved replacement parts can be purchased through Geotech. See Section 7: Replacement Parts List. -
Page 23: Section 5: System Troubleshooting
Do not operate equipment if it has been damaged, broken, smashed, or excessively worn. Broken components pose a severe threat to the safety of the operator and his or her environment. Contact Geotech for any service or repair needs. Problem: Air in fluid line or flow cell. -
