In order to ensure that your pump has a long service life and operates properly, adhere to
the cautions below and read this manual before use.
For long term storage greater than 1 week, care should be taken to clean and dry all pump
components. This will help with long term reliability. An inert lubricant can be used on the
o-ring seals to promote longevity and elasticity.
Pump operation and decontamination should be performed to your standard operating
procedures.
Operation of system utilizing non-Geotech OEM parts could result in equipment failure or
malfunction. This includes air and fluid tubing.
Avoid operating the system without securely anchoring safety cable attached to down
well components.
Always wear gloves and be mindful of contaminated fluids contacting your person and entering
the environment when operating any ground water sampling device.
Do not operate this equipment if it has visible signs of significant physical damage other than
normal wear and tear.
Notic for consum rs in Europ :
This symbol indicates that this product is to be collected separately.
The following apply only to users in European countries:
This product is designated for separate collection at an appropriate collection point.
Do not dispose of as household waste.
For more information, contact the seller or the local authorities in charge of waste

Chapt r 1: Syst m D scription
Function and Th ory
Geotech’s pneumatic Portable Bladder Pumps operate with a unique action, ideal for both gen-
tle low-flow sampling and high flow rate purging. Timed on/off cycles of compressed air alter-
nately squeeze the flexible bladder to displace water out of the pump to the surface and
exhaust allowing the pump to refill.
Fluid enters the pump through the fluid inlet check valve at the bottom of the pump body, via
hydrostatic pressure (automatically by submergence). As a result, the entire pump MUST be
submerged to operate. Next, the internal part of the bladder fills with fluid. Compressed air en-
ters the space between the bladder and the interior of the pump housing. The inlet check valve
closes and the discharge check valve (top) opens. Compressed air squeezes the bladder,
pushing the fluid to the surface. The discharge check valve prevents back flow from the dis-
charge tubing as the inlet check valve opens again to fill the pump. Therefore, the discharge
check valve engages during the fill cycle and disengages during the exhaust cycle. Driven by
the GEOCONTROL PRO or GEOCONTROL II, this cycle automatically repeats.
An optional drop tube can be used to sample from depths below the specified maximum sam-
pling depth. The drop tube assembly connects a remote intake to the pump through a tube
connected to the pump inlet. The intake depth can be any custom length of tubing. The pump
assembly itself must still be submerged below the water level. This means the depth to water
cannot exceed the maximum pumping depth of the pump.
Not : Compressed air does not contact the sample. The bladder prevents contact between
the pump drive air and the sample.
Be sure to read and understand your portable generator and/or portable air compressor user
manual for proper installation and operation and Earth grounding instructions. If using portable
compressed gas tanks, be sure to exercise proper caution, use safety protection devices as
outlined by the supplier, and observe any additional safety requirements mandated by local ju-
risdiction.

Syst m Compon nts:
Geotech’s Portable Bladder Pumps consist of four components as follows:
(1) Bladder Assembly
(2) External Pump Housing
(3) Internal Tube Assembly
(4) Inlet Screen Assembly
(5) Optional Drop Tube Intake Assembly
Syst m Op ration:
The user must determine site specific parameters such as water level, recharge rate and adher-
ence to low flow purging guidelines.
READ BEFORE PROCEEDING ANY FURTHER
Before deploying any sampling pump, secure a safety cable to an anchoring point at or near
the well head to the pump.
Geotech Portable Bladder Pumps can be operated using a variety of controllers. Be sure to
consult the user guide specific to the controller you are using.
The Geotech 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 the system specifica-
tions section of this manual for tubing sizes. When using the 1.66" (4 cm) diameter pump, the
larger diameter tube is for fluid and the smaller one for air.
If a Drop Tube Intake assembly is employed, a third tubing line is necessary.
On the .675" (1.7 cm) and .85" (2 cm) diameter pumps, both air and fluid lines are the same
size. The letter “A” has been stamped near the hose barb on the top of the pump. This indi-
cates the air supply and exhaust line barb. The remaining barb is for the discharge fluid line.

Failure to attach air and fluid lines to the appropriate ports could result in damage to the
bladder.
Use of an air source and controller no supplied by Geotech could result in pressure buildup
and unexpected pressure storage in the pump and airline. Therefore, operation of the pump is
not recommended with equipment other than that provided by Geotech.
Once tubing and safety cable are in place, slowly deploy the pump, screen first, 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. To operate as designed, the pump should be fully submerged. Opti-
mal pump performance is achieved with submergence of greater than 10 feet of water column.
Less submergence could result in reduced pumping performance depending on type of fluid*
being pumped and physical condition of the bladder. Older, worn bladders can develop a
shape memory and may not be able to fill completely without sufficient submergence. In any
case, pumping will still be achieved and the sampling event can be completed.
A thin, less rugged bladder could fill more easily in lower submergence applications. Geotech
has chosen to implement the use of more reliable heavy walled Poly or robust PTFE material to
accommodate longer life of the bladder and overall reliability of the pump.
* Designed for pumping groundwater only, other fluids at user’s risk.

Once the pump is at the desired level within the well bore, set the controller timers to pressur-
ize and exhaust. These settings should be such that the bladder is never over compressed. A
good rule of thumb is to set the pressure cycle so that the fluid stream exiting the fluid line just
starts to fall off when the Discharge/Charge timer expires. If the controller being used has a
pressure gauge, you will notice the pressure level will climb and then ‘stall out’ during pumping
and start to ‘climb’ after all of the water has been evacuated from the pump. If you notice the
pressure climbing after a pump cycle, reduce the pressurization time.
Using the volume per cycle specifications guide in this manual, set the exhaust/delay time to
optimize the amount of fluid discharged during the pressure cycle.
Both fill/exhaust times and discharge/pump times will vary depending on submergence, depth
to water, tubing size and overall tubing length.
For deployment of optional Drop Tube Assembly attach desired length of drop tube to the in-
take hose barb and hose barb on bottom of pump. Send the drop tube intake down the well
followed by the drop tube tubing, then the pump and finally the air and fluid discharge lines.
More information can be found in the user manual specific to the controller you are using.

Slide bladder (#21150054) onto the center
tube assembly and over the O-ring
(#11150319) on the upper end of the center
tube assembly. Be careful not to roll the O-
ring when sliding the bladder over this end.
Slide a Teflon®compression ring (#11150042)

and upper end of the center tube.
With the upper end of the bladder secured by
the Teflon®compression ring, slide the second
compression ring over the bladder about mid-
way down the assembly.
Slide the bladder up, beyond the bottom of
the center tube assembly, exposing the lower
end of the center tube and install the O-ring
(#11150319) into the groove on the lower end.
Slide the bladder back down over the O-ring
being careful not to roll the O-ring.
Now slide the Teflon®compression ring over
the bladder until it seats flush with the bottom
of the center tube assembly.
Replace the outer housing (21150041). Be
sure the outer housing is sealed against the
upper cap.
Replace the bottom intake assembly
(51150067) by screwing it into the bottom of
the pump. There shouldn't be any gaps be-
tween the outer housing and top or bottom
caps.
Inspect O-rings and bladder for damage.
Replace if torn, ripped or excessively worn.
