| High Quality Samples: Consistently accurate samples with
excellent VOC sample integrity.
Simplicity: The controller, air compressor and flow-through
cell can be easily transported by one person to any site.
Hookup to the pump is by compression fittings. 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 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. |
| 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. |

or PVC 1.66" (42 mm) |
| 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. |

| 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. |
| 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. |
 Dedicated Well Caps 2" and 4" (50 mm and 100 mm) |
| 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. |
| 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. |

| 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. |
| 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. |

| 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.

| 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. |
| 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. |
| 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. |
