Solinst Model 407 Bladder Pump
Provide consistent, accurate, reliable groundwater samples by ensuring no air/water contact during sampling.
The Solinst Bladder Pump allows 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 ensures that drive air or gas does not contact the sample, thus avoiding degassing or contamination of the sample. Solinst Bladder Pumps are rugged and long lasting. Teflon® bladders are ideal for dedication, while less expensive polyethylene bladders are available for those that prefer to change bladders after each use. Bladders and intake filters are easily replaced in the field in just a few minutes. No special tools required.
Excellent for either regular flow or low flow sampling, the stainless steel pumps can lift from depths up to 500 ft (150 m) below grade.
Solinst Bladder Pumps are manufactured from 316 stainless steel and have Teflon check balls. The bladder most frequently used is Teflon, however polyethylene bladders are also available. This is the ideal sampling pump for most types of municipal, industrial and general environmental applications, especially where VOC analysis of the sample is important.
The pump body of the standard Solinst Bladder Pump is a convenient 1.66" dia. (42 mm) and comes in lengths of 2 ft and 4 ft (0.6 m and 1.2 m). 1" dia. (25 mm) bladder pumps are also available for narrower applications.
