EON sells and rents Geotech portable and dedicated Bladder Pumps for groundwater sampling with minimal agitation to depths of 1 to 1,000 feet. Geotech pumps are an excellent choice for low-flow sampling and are available in dedicated and portable configurations.
Our pumps were designed with input from field technicians who actually do the sampling. We know from experience, having these pumps in our rental fleet, that they are reliable and easy to use. Pumps disassemble easily and replacement bladders slide securely into place without the need for cumbersome "grab plates". Sizes from .675-inches to 1.66-inches enable sampling from wells as small as 3/4-inch diameter.
For most applications less than 100 feet deep, we recommend the portable Geocontroller a small, highly portable, self contained Compressor & Controller in one.
Extra bladders are readily available in Teflon® and Polyethylene for all models.
A complete Bladder Pump system requires 4 components: a pump, a compressed air source, a controller and tubing (sized to match the pump fittings).
Note: GPB315 (1.66-in Bladder Pumps) use .170-ID tubing for air and 1/4-ID tubing for water. All other pumps use .170-ID tubing for air and for water.
