Section 1: System Description
Function and Theory
The Bladder Pump (BP) Controller 300 PSI is a high-pressure pump controller that uses
advanced electronic logic to control gentle low-flow sampling. Equipped with a highpressure solenoid activated valve and self-relieving regulator, the BP Controller can purge
depths down to 690 feet/210 meters.
This controller connects to any Bladder Pump (BP) system with the use of simple push-toconnect hose adapters. The two timers are adjusted to set the amount of time that the
pump pressurizes (discharge cycle) and depressurizes (fill cycle). During the discharge
cycle, the pump pressurizes squeezes the bladder, forcing the sample through the center
discharge line. During the fill cycle, the compressed pump now exhausts through the
controller vent allowing the pump to fill again, hydrostatically.
A user-friendly interface visually communicates operating status of the controller, as well
as informing the user of low battery conditions. The BP Controller is compatible with Water
Level Meter equipment by connecting a drawdown cable.
System Components
The control panel is mounted inside a heavy-duty carry case for ease of mobility and longterm durability. Accessories for the BP Controller consist of high-pressure Air-In (from
supply) and Air-Out (to pump) hoses, and an AC and DC Power Cord.
Air Connections – the couplings on the AIR IN and AIR OUT Hose Assembilies are Pushto-Connect fittings; press the socket onto the plug until a ‘click’ is heard. It should be a
secure fit which can not be pulled off when tugged. To remove the coupling, push down on
the socket’s jacket and the connection will ‘pop’ out (see Figure 1.1)
Figure 1.1: Push-to-Connect fitting

Section 2: System Installation
Power Source
Determine your power source, either 115 VAC or 12 VDC. Power connects are on the
side of the control panel.
If using Water Level Meter Equipment, connect a drawdown cable to the ‘AUX INPUT’.
Selecting an Air Source
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.

Calculation guideline:
Volume of Tubing (in³/cm)
+ Volume of Bladder Pump (in³/cm³)
= Air Consumption per cycle (in³/cm³)
CAUTION
The BP Controller requires dry, moisture free air.
Disregarding this caution can increase the likelihood of
unnecessary maintenance.

The formulas stated above are not absolute, and are meant
to provide baseline information.
NOTE
Example (use metric units when applicable):
Using an 18” bladder pump and 0.17” I.D. tubing, what size compressor is recommended
to purge a sample 200’ deep?
Step 1: Determine air consumption per cycle.
In this case the 1.66 BP 18” pump is used with 200’ of 0.17” I.D. tubing.
Volume of tubing = 30 in³ * 2 = 60 in³
Volume of pump = 39 in³
Total air consumption per cycle = 60 in³ + 39 in³ = 99 in³
Step 2: Determine air consumption per hour.
Assuming the pump cycles no more than 6 times per minute, we can estimate maximum
air consumption per hour.
99 in3/cycle * 6 cycles/min * 60min/hour = 35,640 in3/hour or 21 ft³/hour
If you plan to use an air compressor, we advise that you use one with a reserve tank to
insure proper air supply to the pump. If you plan to use a Nitrogen Tank, see Figure 2.1 for
Nitrogen Tank Volume vs. Bladder Pump consumption.
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 this 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
Example (use metric units when applicable:
For a pump 400 ft. away from the air source
(400 ft. * 0.5 PSI) + 10 = 210 PSI
As mentioned above, the additional 10 PSI/ 0.7 bar is to account for the pump itself and
friction loss along the airline tubing. When the length of the airline is 50 ft./15 meters or
less, there is no need for the additional pressure.
To determine minimum operating pressures for the specific Bladder Pump model you are
using, consult the pump’s specifications. Typically, the minimum operating pressure will be
5 PSI/ 0.4 bar above static head.

General Operating Definitions
The BP Controller interface utilizes ‘FILL TIME’ and ‘DISCHARGE TIME’ to identify the
alternating timed air cycles. The ‘STATUS’ light will indicate the current cycle or error
code.
FILL TIME – during this cycle, the controller is exhausting compressed air from the BP
system (tubing and pump) to allow hydrostatic fill of liquid within the pump.
DISCHARGE TIME – during this cycle, the controller is routing compressed air into the BP
and squeezing the flexible bladder, which then displaces liquid up the discharge line.
STATUS – the LED on the control panel will visually communicate the status of the
sampling system:
Battery Overdraw Protection
The controller is designed to stop cycling if there is a potential for battery overdraw, as an
overdrawn battery cannot be recharged and reused.
- A flashing red LED will indicate that your power source is in a critically low condition.
- A solid red LED will indicate that the controller has stop cycling to help protect
against battery overdraw.
Operating Battery Voltage
11.7V to 14V
Critically Low Battery Voltage
11V to 11.6V
Low Battery Voltage
below 11V
*Recharge Voltage required to re-engage
12.8V
*If the controller’s power source is connected to a solar panel for battery recharge, the
battery will have to be recharged to 12.8V or above before the controller will continue
cycling.

NOTE
Section 3: System Operation
The BP Controller 300 PSI has a normally closed valve. Therefore, if power is
disconnected from the unit, the controller will automatically stop the flow of air. This helps
to protect the integrity of the bladder and protects against draining the air source.
Quick Start Guide
1. Connect Power Supply to side of controller (see ‘Power Source’ in Section 2).
2. Connect drawdown cable to Water Level Meter equipment (if applicable).
3. Set FILL TIME and DISCHARGE TIME knobs to approximately 30 seconds.
A low cycle time limits the amount of initial pressurized air entering the pump, so as not to
collapse the bladder.
4. Flip BP Controller power switch to the ON position.
After about 30 seconds, there should be a distinct ‘click’ when the solenoid valve shifts.
If the controller only cycles once and then displays a red light, there is not sufficient power
from the battery. See Section 5: Troubleshooting for more information.
5. Connect ‘AIR OUT’ hose socket to the ‘AIR OUT’ plug on the control panel (1/4”
coupling size). Connect the other end of the ‘AIR OUT’ hose to the pump airline
on the wellhead (1/4” quick-connect fitting).
See ‘System Components’ in Section 1 for details on the air connection couplings.
6. Connect the unpressurized ‘AIR IN’ hose socket to the ‘AIR IN’ plus on the
control panel (3/8” coupling size). Connect the other end of the ‘AIR IN’ hose to
the regulated air supply (compressor, bottle, tank, etc.)
7. Adjust the air source to the appropriate PSI (MAXIMUM: 300PSI/ 20.7 bar). See
‘Determining PSI’ in Section 2).
8. Adjust the FILL TIME and DISCHARGE TIME based on pump and well
specifications (see ‘Adjusting Cycle Timers’ in Section 3 for guidelines).
a. Let controller cycle until fluid starts pumping from discharge tubing
b. Adjust DISCHARGE TIME so that the air supply turns off when fluid
stops flowing from tubing
c. Adjust FILL TIME to desired setting that allows pump to hydrostatically
fill
9. When pumping is complete, turn off air supply (exhaust excess air if applicable)
and flip BP Controller power switch to the OFF position.
10. Take caution in disconnecting hoses, as the system may be slightly pressurized.
Hoses and power adapters are stored in the accessory bag.
The controller has an imbedded safety relief valve, which will exhaust
compressed air that enters the system in excess of 350PSI/ 24 bar.
To reset the relief valve and allow air through the controller, incoming
air must be regulated to 300PSI/ 20.7 bar or below.
10
NOTE
Adjusting Cycle Timers
The FILL TIME and DISCHARGE TIME knobs have a large diameter for maximum
resolution. The timers have a range from 5-120 seconds.
Adjust DISCHARGE TIME knob to approximately 10 seconds, and adjust FILL TIME knob
to approximately 30 seconds. A 30 second exhaust cycle (FILL TIME) will be enough time
to hydrostatically fill a bladder at approximately 100 ft. (30.5m) deep.
The DISCHARGE TIME cycle can be adjusted by watching the sample line. When a
steady stream of water stops during the cycle (STATUS light = green), set the
DISCHARGE TIME back about five seconds.
Once the DISCHARGE TIME is adjusted, measure the volume of the sample and adjust
the FILL TIME back about one second. Let the pump cycle a few times after each
modification before adjusting again. Measure the volume of sample to make sure it is not
decreasing. Continue to reduce the FILL TIME back until the sample volume decreases. A
decrease in sample volume indicates that the exhaust cycle (FILL TIME) is not long
enough for the pump bladder to fill to its maximum capacity. Add one second to the FILL
TIME at this point to make sure the maximum volume in the bladder is achieved.
The following Fill cycle time guidelines are based on a 0.5”/1.3 cm I.D. airline tube:
TYPE
DEPTH
DISCHARGE TIME
Standard Sampling
up to 172 ft. / 52 m
0-30 seconds
Deep Well Sampling
up to 345 ft./ 105 m
0-60 seconds
Max. Depth Sampling
up to 690 ft./ 210 m
0-120 seconds
Discharge and Fill times will vary depending on the depth of well and
size of airline tubing.
DO NOT OVER PRESSURIZE (DISCHARGE TIME) as this will
cause excessive bladder wear.
CAUTION

Section 4: System Maintenance
The BP Controller does not require a regular maintenance program; however, proper care
will ensure reliability.
As stated in installation and operation, this unit requires dry, moisture-free air. To
disregard will increase the likelihood of unnecessary maintenance or hardware
replacement.
To keep your BP Controller reliable, follow these simple guidelines:
Do not drop your BP Controller.
Do not immerse your BP Controller.
Do not subject your BP Controller to poor power supplies.
Do not subject your BP Controller to extreme heat or cold when in use.
Controller:
Keep your BP Controller clean and dry. In the event that the controller is subjected to
significant splashing or immersion, discontinue use and wipe the unit down immediately
with a clean dry cloth.
Let the controller dry out in between uses by opening the carry-case. When closed the
carry-case has a waterproof seal and will trap in unattended water.
Power Cords:
Always replace a kinked or damaged power cord.
Air Connections:
When build up is present, clean the AIR IN and AIR OUT coupling connections using a
phosphate-free cleaning detergent and water solution.
Solenoid:
Qualified personnel may clean the solenoid. Disassemble the solenoid and clean inner
components. Lubricate shuttle after cleaning, and reassemble in reverse order.

Section 5: System Troubleshooting
Problem: Unit will not turn on.
Solution:
Check power source and cables for damage.
If using a battery, see Section 2, ‘Battery Overdraw Protection’.
If using DC, verify that you have a 12 VDC power source. If on AC, verify that
you are getting a consistent 115 VAC current.
Problem: Unit turns on but cycles rapidly, no pumping.
Solution:
Discharge and Fill times not set correctly.
Check and adjust Discharge and Fill cycle times (i.e., if discharge time too long
and fill time too short, or discharge time too short). Review Section 3 for correct
cycle times.
Problem: Turns on, cycles correctly but does not pump water.
Solutions:
Check for tubing kinks.
Pressure may be too low, check the gauge. Calculate based on 0.5 PSI per foot
(.1 bar per meter) of head and add 10 PSI (.7 bar) for friction.
Increase FILL TIME. The pump needs to depressurize to allow pump to fill.
Solenoid may have moisture or debris build-up. Maintenance may be in order.
Problem: Unit was working, but stopped cycling.
Solutions:
Check power source.
If using a battery, see Section 2, ‘Battery Overdraw Protection’.
If power source is good, check air source.
Air source is good - have you been using clean dry air? If not contact Geotech at
