The Solinst Integra® Bladder Pump allows consistent, high quality samples in all types of applications. It offers 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 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. The PVC Integra operates up to 100 ft (30 m) below grade.

Low purge volumes ensure rapid sampling. Cost Savings: Reduced need for repeat sampling and shorter time required for each sampling round. Bladders: Durable Teflon bladders are ideal for dedication. Inexpensive polyethylene is also available.

 

Low Flow Purge and Sampling
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 Solinst Model 466 Electronic Pump Control Unit, the Solinst Integra Bladder Pump can be adjusted to provide continuous output of 100 ml/min. 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.

 

The Integra Bladder Pump
Integras 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. For metals analysis and situations with highly corrosive liquids, the PVC Integra is more suitable. It has Teflon check balls, a porous polyethylene screen and may have either a Teflon or a polyethylene bladder. The low cost of the PVC pump also makes this a perfect choice for situations where there is a limited budget, but dedicated bladder pumps would be preferred. The pump body of the standard Integra 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 and for use in the Waterloo Multilevel System.

Integra Bladder Pumps available in Stainless Steel 1" and 1.66" (25 mm and 42 mm) or PVC 1.66" (42 mm)

 

Portable Integra Pumps
For less frequent sampling, and to allow access to multiple monitoring wells, even in remote locations, portable Integra pumping systems are available. They may be supplied on a freestanding reel, or mounted on a cart with the tubing and pump controller. The rugged cart mounted system uses large pneumatic tires for easy transport over rough terrain.

Dedicated Systems
For long term monitoring it is always best to dedicate Integra Pumps. This avoids cross-contamination and saves time without the need to decontaminate between sampling events. There is the assurance of no air/water contact during sampling, and the confidence that no cross-contamination will occur from the use of portable equipment. Integra well caps are designed for ease of use. The vented PVC caps have a quick-connect attachment for the controller unit/air supply. Fittings are provided for both 1/4" OD (6 mm) and 3/8" OD (9 mm) tubing. Each cap comes with a 3 ft (0.9 m) length of discharge line, which is easily replaced, as required. For water level monitoring there is an access hole to fit a Solinst Model 101 Water Level Meter. An eyebolt is provided for a pump support cable or for suspension of a Solinst Levelogger, or other device.

 

Dedicated Well Caps
The caps slip easily onto 2" dia. (50 mm) wells. Adaptors to fit 4" dia. (100 mm) or other well sizes are also available. The cap seals in place with an o-ring, and comes with a wire connected protective cover. Low profile wellheads are also available for flush mount casing applications.

Converts Easily to Pneumatic DVP
The 1.66" dia. (42 mm) by 2 ft (0.6 m) Stainless Steel Integra Bladder Pump (42 x 610 mm) utilizes most of the same parts as the pneumatic drive Solinst 1.66" Double Valve Pump (DVP). The DVP can operate from greater depths and provide higher flow rates. Conversion from an Integra Bladder Pump to a DVP and back again is quick and easy (approx. 2 min.) and requires no tools.

 

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 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. Electronic Control Unit

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. Solinst provides dedicated systems 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.

 

12V Oil-Less Air Compressor
The Solinst 12 Volt 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 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. 12V Compressor

 

Filters and Packers
Integra Stainless Steel Bladder Pumps come complete with a 50 mesh intake filter over the sample inlet. These filters are very easy to replace. If required, Solinst also supplies disposable in-line filters which are used on the sample discharge tube. They are adaptable to fit many sizes of tubing. Model 800 Low-Pressure Packers can be used with Integra Pumps to minimize purge times by reducing purge volumes. This reduces the cost of water disposal and labour. Packers are available in single point or straddle packer designs, and in sizes to fit 2" ( 50 mm) to 5" (127 mm) dia. wells. Model 800 Packers 3.7" and 1.8"
(94 mm and 46 mm)

 

Easy Decon or Disposable Polyethylene

Bladder Pump Operation
When an Integra Bladder Pump is lowered into a well, hydraulic pressure allows formation water to enter the central Teflon chamber (the bladder) through the inlet filter. When compressed air or gas is applied to the drive line it pressurizes the space around the bladder, causing it to collapse and pushes the water up into the sample line. Check valves ensure that no water flows back down through the pump or into the formation. When compressed air or gas is vented (released), more formation water enters the bladder. When the pressure is reapplied, the fresh formation water is pushed up towards the surface. The pressure/vent cycles are repeated, providing a steady flow of water up the sample line, without any stripping of volatiles from the sample. Turbidity is minimized due to the low flow rates and the gentle pumping action. Thus a high quality VOC groundwater sample is obtained.

 

Higher Flow Rates
When larger purge volumes are required, Solinst Integra Bladder Pumps can deliver flow rates up to 2 L/min. Alternatively a simple conversion kit can be used to quickly turn a stainless steel Integra Bladder Pump into a Solinst Double Valve Pump (DVP). These pneumatic drive DVPs can provide higher flow rates and sample from greater depths than most bladder pumps. Flow rates vary with depth of pump below surface, depth below water level, size of drive and sample tubing, drive and vent cycle times, gas pressure applied and aquifer recharge. Flow rates of the Integra Bladder Pump and the DVP compare favourably with published data for similar types and sizes of pumps, under similar conditions. For example: 1.66" x 2 ft (42 mm x 610 mm) Bladder Pump at 100 psi, with 1/4" OD drive line and 3/8" OD sample line; 50 ft (15 m) below grade with 25 ft (7.5 m) below water level gives 2 L/min.
