Low flow sampling offers excellent quality samples by reducing turbulence. It also reduces purge volumes, and thus sampling time and disposal costs. When using a Solinst Model 464 Electronic Pump Control Unit, the Solinst Bladder Pump can be adjusted to provide continuous output of 100 ml/min. or less.
Use of a Flow-Through Cell System during low flow sampling, allows the continuous analysis of purge water, in-line, as it flows, so that sampling can begin as soon as the readings stabilize.
Packers are also available to further reduce purge volumes and to speed sampling times.
Stainless Steel: 1.66" Ø (42 mm) and 1" Ø (25 mm) with 316 stainless steel body.
Non-Vertical Applications: Pumps operate effectively at almost any angle and can be placed under landfills, tailings, storage tanks or contaminant plumes.
Leachate/Product Pumping: Pneumatic drive pumps are well suited for pumping contaminant liquids. Strong solvents and corrosive chemicals can be easily and economically pumped.
Survives Dry Pumping, Dirty Air and Sand: Solinst bladders are not damaged by operation in sediment laden water, or in dry pumping conditions.
Freeze Protection Kit: Optional accessory available to prevent freezing in the sample line.
High Quality Samples: Consistently accurate samples with excellent VOC sample integrity.
Simplicity: The controller, air compressor and flow-through cell can be easily transported by one person to any site. Hookup to the pump is by compression fittings.
Cost Savings: Reduced need for repeat sampling and shorter time required for each sampling round. Low purge volumes ensure rapid sampling.
Bladders: Durable PTFE bladders are ideal for dedication. Inexpensive polyethylene is also available.
