Solinst Model 407 Bladder Pump Groundwater Samplers

Solinst Model 407 Bladder Pump Groundwater Samplers provide consistent, accurate, and reliable groundwater samples in all applications. Ensuring no air/water contact during operation, pumps are ideal for VOC sampling.

PTFE bladders are ideal for dedication. Inexpensive polyethylene bladders are also available. Stainless steel pumps are effective at any angle, to depths of 500 ft (150 m), and are ideal for low flow sampling.

Low Flow Purge and Sampling

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.

Features of Solinst Model 407 Bladder Pump Groundwater Samplers

Stainless Steel: 1.66″ Ø (42 mm) and 1″ Ø (25 mm) with a 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.

Benefits of Solinst Model 407 Bladder Pump Groundwater Samplers

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 PFAS-free PTFE bladders are ideal for dedication. Inexpensive polyethylene is also available.
