The Geotech deep water level groundwater sampling system consists of a high-pressure airbag pump, controller, and gas supply source. Both shallow airbag pumps and high-pressure deep water level airbag pumps can be applied to low flow groundwater sampling work, thereby obtaining the most representative samples with minimal disturbance.

High pressure airbag pump:

The Geotech high-pressure airbag pump can sample at a depth of 1000 feet (305 meters) from the static water level. If larger depth samples are collected, an extended sampling tube needs to be connected.

features:

• Low disturbance, truly achieving low flow sampling; There is a sieve at the inlet to trap larger particles, which can extend the lifespan of the airbag

• Resin grade native PTFE airbag with long service life; Made of 316 stainless steel material, with strong durability

• The optional Drop Tube component can expand the sampling depth

• Compatible with other models of Geotech controllers (GeoControlPRO or BP)

Pump body parameters:

controller:

The controller of the Geotech deep water level groundwater sampling system (300PSI or 500PSI) is easy to operate and uses precise microprocessors to control the inflation/exhaust time to achieve true low flow sampling. Both the 300PSI and 500PSI controllers are equipped with high-pressure valves and fine resolution regulators that can be applied in deep water levels. Both models of controllers can be connected to any groundwater bladder pump sampling system from Geotech.

features:

• sturdy and durable

• High pressure operation, applicable to greater working depths (static water level depth)

• Multiple power input options (DC/AC)

• Precision of microprocessor controlled timer

• Internal overvoltage protection

• The controller is fixed in the portable case for easy portability

• Compatible with water level gauge, capable of achieving water level drop control

Gas source:

The use of the Geotech deep water level groundwater sampling system requires a suitable gas source, and the selection of the gas source should be based on the depth of the static water level at the sampling point. Generally, high-pressure gas cylinders or air compressors are needed. Please contact us for detailed information.
