Pneumatic Samplers

407 Integra™ Bladder Pump



 

The 407 Integra™ Bladder Pump has a Teflon® bladder guaranteed for 10 years. Solinst offers 316 stainless steel Integra pumps in diameters of 1” and 1.66” (25 mm and 42 mm) and PVC Integra Pumps in 1.66” (42 mm). They are ideal for low flow sampling but can also be used for regular flow sampling. Maximum lift capabilities are 500 ft. (150 m) with the stainless steel models and 100 ft. (30 m) with the PVC.
Dedicated systems may be purchased pre-assembled for easy installation, complete with well caps and tubing. Portable systems are also available as illustrated. Cart-mounted portable pumps have pneumatic tires and a lowering guide for easy use.
 
 

408 Double Valve Pump (DVP)

 

The 408 Double Valve Pump (DVP) is similar to the Bladder Pump, but without a bladder. It is a gas drive pump suitable for applications of almost any depth and narrow diameters. It is available in stainless steel in 1.66" or 5/8" diameter (42 mm or 16 mm) and in PVC in 1.66" (42 mm). Portable and dedicated versions are available. The DVP 1.66” (42 mm) converts easily into a Bladder Pump, if desired.
All pumps can be quickly disassembled for decontamination, and are operated using the Model 466 Electronic Control Unit. Pumps may be fitted with pneumatic/hydraulic packers to reduce purge volumes.

466 Electronic Control Unit


 
 

 

 
The 466 Electronic Control Unit controls the supply of compressed gas to pneumatic pumps including the Integra Bladder Pumps and Double Valve Pumps. The Control Unit uses simple, preset sample modes to allow easy selection of the desired sample rate, with controls for further fine- tuning. The sampling rates may be selected to ensure a representative low-flow sample at 100 ml/min or less. Higher flow rates for purging may also be chosen. The Electronic Control Unit is available in 160 psi and 250 psi models. The Controller uses 8 AA batteries, that allow continuous operation for up to 30 hours, and can be easily replaced in the field.

407 Accessory 12 Volt Compressor
 
The 12 Volt Compressor is lightweight and compact, ideal for field use. It uses any 12 volt DC power source, such as a car or truck vehicle battery, and comes with alligator clips. The compressor operates at 125 psi and is equipped with a 2 US gallon (7.6 liter) air tank which is rated to 150 psi.
 

Other Samplers

410 Peristaltic Pump







 




 

The 410 Peristaltic Pump operates to the suction lift limit, allowing vacuum pumping or pressure delivery of liquids or gases. It is ideal for sample removal from shallow wells and surface water, as well as air sparging. The Solinst Peristaltic Pump has a variable pumping rate and uses either 3/8" or 5/8" (10 mm or 16 mm) silicon tubing.
The power cable is fitted with alligator clips and uses any 12 volt external DC supply. It can deliver from 50 ml/min. to as much as 3 liters/min. The pump is very compact and easy to use, with a handle and easy-access controls on the top of the pump. The metal case is water resistant and has no grates or openings.
                                               

                 


 

425 Discrete Interval Sampler

 
The 425 Discrete Interval Sampler is excellent for obtaining representative groundwater samples from below product layers, or for sampling within floating or sinking product layers, and also for sampling at discrete depths in a well. The reel mounted stainless steel sampler has a convenient sample release device and is easy to decontaminate without the need for tools. It is pressurized with a hand pump before entering the well. No water flows through the sampler on the way down the well. When the pressure is released, the sampler fills directly from the sampling zone.
 

404 Waterra Pump


 

The 404 Waterra Pump is ideal for dedication. The system includes a simple footvalve and length of polyethylene tubing, which is very inexpensive. Sampling to depths of 100 ft. (30 m) can be performed by hand, or with the inexpensive hand pump handle, and to 250 ft.(75 m) with an electric or gasoline pump controller. The WaTerra Pump is suitable for purging, sampling and developing wells. It easily handles heavily laden, silty water. A variety of footvalve sizes, surge blocks, filters and 4 tubing sizes are available.


 

PointSource Sampling

Point source sampling can be used toprofile an open borehole or screened well, to collect samples from distinctlevels or points of inflow. There is negligible disturbance as can be caused bypumping and purging. Mixing of the sample with water from different levels inthe well is minimized.
Purging and disposal of purgedwater can be avoided, because sampling directly from a specific depth collectsthe water that has just flowed into the well at that depth.

Solinst also manufactures theModel 425 Discrete Interval Sampler which is pressurized before lowering intothe well to prevent water from entering the sampler until the sampling zone hasbeen reached.

The Model 425T Transportable DISis similar, but uses special shut-off valves to retain the volatiles in a zeroheadspace sample, in down-hole condition, during transport to the laboratory.Both Discrete Interval Samplers are described on DataSheet 425.


Point SourceBailer

The Solinst Point Source Bailer has dualball valves, top and bottom. This prevents a sample collected at a discretedepth from mixing with water from other depths during retrieval.
The Point Source Bailer is a simple andcost effective device for aquifer profiling. It needs no costly or hard totransport ancillary equipment, making it ideal for point source sampling inhard to access locations.
The miniature 0.5"(12.7 mm) diameter model is ideal for use in narrow tubes and drive-pointdevices.
