Bladder pump uses check balls above and below the bladder to control flow direction as the inner tubing is moved up and down to expand/compress the bladder.
The Geoprobe® Model MBP470 Mechanical Bladder Pump offers a better way to meet low flow groundwater sampling requirements because it saves money with less field effort!
- Obtain high-quality, low-turbidity groundwater samples from wells or direct push installed groundwater samplers as small as 0.5 in. ID>
- Conduct low flow, minimal drawdown sampling to meet the most stringent EPA requirements for Volatile Organic Compounds (VOCs). Read more...
- Less expensive to use than pneumatic bladder pumps.
- Used as a portable bladder pump or dedicated to monitoring wells to minimize potential for cross contamination.
- Requires no compressor, generator, or pneumatic controller.
- Can be operated in simple, manual mode or with a manual actuator.
- No difference in sample quality when operated at same flow rate as a conventional bladder pump.
- All metal components are stainless steel to further assure sample integrity and regulatory acceptance. The photo above right shows installing the inlet/check ball retained on the lower end of the mechanical bladder pump.
In the photo shown at left, a corrugated Teflon® bladder, housed inside the stainless steel body, is lowered into the well casing of a monitoring well. Check balls above and below the bladder control flow direction as the inner tubing is moved up and down to expand/compress the bladder.
The U.S. Environmental Protection Agency's Environmental Technology Verification Program (ETV) recently finalized their performance statements on the Mechanical Bladder Pump developed by Geoprobe Systems®, and has given the company and the MBP high marks. The document stated that the MBP collected representative samples and met low flow groundwater sampling protocol recommended by the EPA and many state agencies.

When operating the mechanical syringe or bladder pump, Geoprobe® recommends using the mechanical actuator (MN 214106) for sample collection.
