  • Page 5: Chapter 1: System Description

    Chapter 1: System Description Function and Theory Geotech’s pneumatic Bladder Pumps operate with a unique action, ideal for both gentle low-flow sampling and high flow rate purging. Timed on/off cycles of compressed air alternately squeeze the flexible bladder to displace water out of the pump to the surface and then exhaust allowing the pump to refill.
  • Page 6 *Optional: Drop Tube Intake Assembly Bladder Cartridge Assembly Geotech’s 1.66” (4 cm) Bladder Cartridge Assembly (for 18”/46 cm and 36”/91 cm lengths) is factory assembled and tested, and is designed to be field replaceable. The .850” (2 cm) and .675” (1.7 cm) Bladder Cartridge’s are easily replaceable see, Chapter 4: System Maintenance.

    Pump Tubing Lines Geotech’s Bladder Pumps are engineered for easy installation and use. Dedicated Bladder Pumps are available with the tubing attached. Well identifications (supplied by customer) are located on tags connected to the tubing, and on the tubing bags.
  • Page 9 Safety Cable Before deploying any sampling pump, secure a safety cable from an anchoring point at or near the well head to the top of the pump. The optional Bladder Pump Hanger is attached to the Quick Link on the safety cable. Carefully lower the Bladder Pump into the well using the Reverse Coil Method to avoid kinking, until the desired depth is achieved or until the well cap seats.

  • Page 11 Flowrates depend on pump size and pump depth. For example, a large pump at shallow depths will produce the most flow, and a small pump at maximum depths will product the least amount of flow. Speak with a Geotech representative to determine the best configuration to meet sampling needs.

    Chapter 4: System Maintenance Bladder Pump As with any pump, scheduled or periodic maintenance should be performed, according to your sampling program and specific site conditions. Generally, the more turbid or sandy the water, the more maintenance and cleaning are required. Replacement bladders, as well as other key components, can be found in Chapter 7: Replacement Parts List.
