The Sample Pro Portable MicroPurge Pump is the first pump developed specifically to bring the advantages of low-flow sampling to sites where groundwater samples are collected from many monitoring wells with the same pump. The Sample Pro Pump is easy to disassemble, without any tools, and simple to clean to eliminate any potential cross contamination. That includes the exclusive SamplePro disposble bladder, which snaps in and out without any clamps, so they can be discarded after each well is sampled. The SamplePro pump is available in two diameters: 1.75" (4.45cm) to fit in 2" (50mm) monitoring wells or larger; and 3/4" (1.91 cm) to fit small diameter wells and direct-push boreholes. Both pump models are capable of pumping from depths up to 200 feet (61m).
How the SamplePro Works:
The SamplePro Portable MicroPurge Pump uses a quickchange, one-piece bladder design. Compressed gas squeezes the outside of the bladder to force liquid out of the pump; there is no gas contact with the pumped water inside the bladder. Squeeze type bladder pumps are supported by years of independent research that shows they provide unaltered samples for even the most sensitive parameters. Groundwater enters the pump through the inlet in the upper, head section, then flows down into the bladder. The high inlet helps keep the pump from clogging if it isaccidentally lowered into a sediment-filled sump. Check valves with stainless steel seats and check balls are located at the inlet and outlet. Inlet screens are replaceable to help ensure proper sealing of the check valves in wells with high solids levels. The Sample Pro Pump is shipped in a heavy-duty tube with rubber end caps to help keep the pump clean and protected between uses. The pump is disassembled by a 1/4 turn of the cap and body; no special tools are needed. The bladder pulls off for replacement. Both check valves are press-in, pull-out design, and use Teflon for the fluid inlet and stainless steel in the fluid discharge.

SamplePro
Advantages
▼ Exclusive Sample Pro
disposable bladder is quick &
easy to replace in the field, for
fast cleaning.
▼ Rugged, reliable, complete
system designed for easy use in
the field.
▼ Quick 1/4 turn disassembly
with no tools means simple,
fast and complete field
cleaning. Disposable bladders
and push-in tubing replace in
seconds, speeding you on to
the next well.
▼ Solid stainless steel
construction is truly durable,
with no motors, bearings, or
impellers to go bad. Even if the
pump fills with silt, it can be put
into action again with a quick,
simple cleaning. Output
pressure is strong and
controllable.

The MicroPurge® Controller revolutionizes low-flow sampling with advanced logic control of flow rate and water level drawdown. Simple up-down arrow keys increase and decrease flow rate, driving a microprocessor to re-create expert techniques for low-flow adjustment. Then, optimized settings are identified for recall in the next round of sampling. The MP10 also offers an easy way to prevent excessive monitoring well drawdown during purging, by linking to the optional MP30 Drawdown/Water Level Meter that ceases flow when drawdown settings are exceeded. The lightweight, compact MP10 sets the pace for a new generation of genuine MicroPurge® equipment, first in control and power for low-flow sampling. Simple, Stable, Repeatable Flow Rate Setting The MP10 controls the most advanced low-flow sampling system ever made. You will purge and sample quickly and easily, with precise, steady low-flow pumping rates from one sampling event to the next. Simplified, sealed electronics complete a design that delivers famous QED durability and value. MicroPurge controllers can be connected to the MP30 Drawdown Meter for optional Automatic Drawdown Control, an industry exclusive.
MicroPurge® Controller Advantages
1. Exclusive MicroPurge® control mode uses simple arrow keys to adjust low-flow
rates easily and repeatably, using a micro-processor to re-create the flow
adjustment strategies used by experienced samplers.
2. Patented connection port allows linking to optional MP30 Drawdown/Water
Level Meter, which signals MP10 Controller to enter stand by mode if drawdown
limit is exceeded.
3. Multi-mode digital control includes MicroPurge Mode, ID Mode for repeat
events, and manual control mode.
4. Weatherproof controls are housed in a rugged, compact (10-3/4” x 9-3/4” x 5”) case.
5. Full digital display of all setting and status information.
6. Optional deep well MicroPurge Controller versions allow for effective low-flow
sampling from depths to 1000 feet.
