MECHANICAL BLADDER PUMP (MBP)

The Mechanical Bladder Pump, manufactured by Geoprobe® Systems, offers a better way to meet low flow sampling requirements because it saves money with less field effort!

The Mechanical Bladder Pump requires no expensive, cumbersome equipment or accessories. Forget about heavy generators, compressors, and pneumatic controllers. This simple, easy-to-assemble pump can collect representative samples for VOCs and other environmental analytes without compromising sample quality.

Operation in the field is simple. All you need is the bladder pump and concentric tubing. The tubing is attached to the top of the pump and extends to the surface. The assembled Mechanical Bladder Pump is then lowered into the monitoring well or into the small diameter groundwater sampler. During operation, the outer tubing is held in place while the inner tubing is raised and lowered. This action alternatively expands and compresses the corrugated bladder inside the pump. A few seconds of pumping brings the fluid to the surface and a sample is quickly retrieved.

The Mechanical Bladder Pump meets low-flow sampling protocol recommended by the Environmental Protection Agency.


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). Less expensive to use than pneumatic bladder pumps. Used as a portable 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 an electric actuator. No difference in sample quality when operated at same flow rate as a conventional bladder pump. All mechanical movement of the Mechanical Bladder Pump is contained inside the pump body to eliminate agitation of water in the well and formation. All metal components of the pump are stainless steel to further assure sample integrity and regulatory acceptance.
