The Solinst Integra Bladder Pumps allow consistent, high quality samples in all types of applications with excellent performance and reliability. With Integra 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. Integra Bladder Pumps are rugged and long lasting. Teflon bladders have a 10-year warranty, while less expensive polyethylene bladders are available for those that prefer to change bladders after each use.

Integra Bladder Pumps are easy to decontaminate. Everything is very accessible. The tubing may simply be flushed or it is easily replaced. The pump is quick to disassemble and the bladders and screens are simple to replace in the field. No tools required. Inexpensive polyethylene bladders can be quickly replaced to suit regulatory requirements. 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. The PVC Integra Bladder Pump operates up to 100 ft (30 m) below grade.

Low flow sampling offers excellent quality samples by reducing turbulence. It also reduces purge volumes, and thus sampling time and disposal costs. When using the Model 466 Electronic Pump Control Unit, the Integra Bladder Pump can be adjusted to provide continuous output of 100 ml/minute or less. Use of a Flow-Through Cell System during low flow sampling, allows the continuous analysis of purge water, in-line, as it flows, so that sampling can begin as soon as the readings stabilize. Packers are also available to further reduce purge volumes and to speed sampling times.

Electronic Control Unit Model 466

Pump Controllers:

The Electronic Control Unit uses 8 AA batteries that provide up to 30 hours of continuous use. It is fully automatic with preset sample modes to give a variety of useful drive and vent cycles. These can be further adjusted manually to optimize the flow. It allows faster purge rates and precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for VOCs. The standard Model 466 Electronic Control Unit gives up to 160 PSI and the 466 HP offers up to 250 PSI output. These convenient boxes are rugged, dependable and suitable for all environments. Quick-connect fittings allow instant attachment to dedicated well caps, portable reel units and through an in-line dryer to an air compressor or compressed gas source.

12V Compressor

12V Oil-less Air Compressor:

The 12 Volt Air Compressor is lightweight 21 lbs (9.5 kg), compact, and ideal for field use, especially low flow applications of less than 100 ft (30 m) depths. The air compressor operates using 12 volt DC power source, such as a car or truck vehicle battery, and comes with alligator clips. The compressor operates at up to 125 PSI and is equipped with a 2 US gallon (7.6 L) air tank which is rated to 150 PSI.

Tubing:

The standard tubing is 1/4” (6 mm) single line or 1/4” (6 mm) OD dual skip-bonded LDPE. Teflon-lined LDPE and other tubing sizes are also available. Dedicated systems are available with individual drive and sample lines so that the cost of replacing the sample line is minimized. Dedicated systems can come pre-assembled to the length you need, at no extra charge. Portable systems are provided with 1/4” (6 mm) dual skip-bonded tubing for ease of operation.
