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 minutesno 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.

Features

• Santoprene Bladders: Santoprene bladders are used for their chemical resistance and inert properties, making them suitable for harsh environments as well as potable water applications.
• Stainless Steel or Low Cost PVC: 1.66″ (42 mm) and 1″ (25 mm) in 316 stainless steel. 1.66″ (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.
