Bladder Pump
The Solinst Bladder Pump features a new design providing consistent, high-quality samples in all types of applications. It offers excellent performance and reliability. With Solinst Bladder Pumps, there is the assurance that there is no air/water contact during sampling. It meets the most rigorous US EPA standards for VOC groundwater monitoring.
The bladder guarantees that drive air or gas does not contact the sample, thus avoiding degassing or contamination. Solinst Bladder Pumps are rugged and long-lasting. Santoprene® bladders are ideal for dedication, however, the new easy-to-replace bladder cartridges are excellent for those who prefer to change bladders after each use. The bladder and intake filters are simply replaced in the field in just a few minutes—no special tools are required.
Excellent for either regular flow or low flow sampling, the stainless steel pumps can lift from depths up to 150 m (500 ft) below grade. The new PVC Bladder Pump operates up to 100 ft (30 m) below grade.
Low Flow Purge and Sampling
Low flow groundwater sampling offers excellent quality samples by reducing turbulence. It also lowers purge volumes, thus reducing groundwater sampling time and disposal costs.
When using a Solinst 464 Electronic Pump Control Unit, the Solinst Bladder Pump can be adjusted to provide a continuous output of 100 ml/min or less. The use of a Flow-Through Cell System during low flow sampling allows the continuous analysis of purge water in-line as it flows, so groundwater sampling can begin as soon as the readings stabilize.
Packers are also available to further reduce groundwater purge volumes, speed up sampling times, and lower purge water disposal costs.
Bladder Pump Features
Santoprene Bladders: Santoprene bladders are used for their chemical resistance, inert properties, making them suitable for harsh environments as well as potable water applications.
Stainless Steel or Low Cost PVC: 1.66" Ø (42 mm) and 1" Ø (25 mm) in 316 stainless steel. 1.66" Ø (42 mm) in PVC.
Non-Vertical Applications: Bladder Pumps operate effectively at almost any angle and can be placed under landfills, tailings, storage tanks or contaminant plumes.
Leachate/Product Pumping: Pneumatic drive Bladder 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 groundwater sampling line.
Benefits of Using Solinst Bladder Pumps
Bladder: Durable Santoprene bladders are ideal for dedication, however, new bladder cartridges make them extremely easy to replace.
High Quality Samples: Consistently accurate groundwater 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 Bladder Pump is by barb fittings.
Cost and Time Savings: Reduced need for repeat sampling and shorter time required for each sampling round. Low purge volumes ensure rapid sampling. Purged water disposal costs are also decreased.
