Sampling Voc S Solinst Bladder Pumps Ideal for voc groundwater sampling. excellent for low flow purge and sampling. portable or dedicated. solinst bladder pumps now feature a simplified cartridge design, allowing the bladder to be easily and quickly replaced in the field—no tools are required. the bladders are made from durable santoprene, which provides many additional benefits. E.g. if the bladder pump's intake is at 100 ft. below ground surface, you will require approximately 50 psi of pressure to bring a sample to ground surface. to be more precise: drive pressure. = (intake depth x 0.43) 10 psi. = (100 x 0.43) 10 psi. = (43) 10 psi. = 53 psi. if you are taking a groundwater sample with a double valve pump.

Sampling Voc S Solinst Bladder Pumps Double valve pumps and bladder pumps are able to provide flow rates as low as 100 ml min, using the solinst electronic pump control unit. the bladder pump allows very slow, steady compression of the bladder during a drive cycle, unlike some other samplers, as it can be set to provide a consistent rate comparable to ambient groundwater flow. When the solinst bladder pump is placed in a well or borehole, water rises inside the bladder and sample tubing to static level. compressed nitrogen or air is supplied to the pump via the drive tubing using a control unit. applying pressure causes the bladder to compress and closes the bottom check valve, forcing water from the bladder into the sample tubing. The stainless steel bladder pump is ideal for most municipal, industrial and general environmental applications to depths of 150 (500 ft). back by popular demand, the new pvc bladder pumps are lower in cost and are excellent for metals sampling and in harsh, corrosive environments to depths of 30 m (100 ft). for more information call us on 61. 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.
