Solinst SS and PVC Model 401 Bladder Pumps

Key Features

• Consistently accurate samples with excellent VOC sample integrity
• Pneumatic drive pumps are well suited for pumping contaminant liquids
• Bladders are not damaged by operation in sediment laden water, or in dry pumping conditions

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.
