Direct push water sampler
The direct push (DP)
procedure is a cheap alternative
to often expensive methods to receive a groundwater sample
Our water sampler types S-9097, DP 32/42 and DP 36/48
are designed for the DP procedure.
The water sampler is driven into the investigation depth
. Water enters the system through a filter and is pumped up through a hose.
This cheap system is mainly used to determine contaminations from contaminated sites
, as well as for site investigations
Expensive and complex gauge excavations
can be avoided using the DP water sampler instead.
Water sampler S-9097
The water sampler S-9097 allows, a cost-effective sampling
of the groundwater and capillary space.
The water sampler S-9097 is driven by hand or with help of a device into the investigation depth. A replaceable external filter
allows water to enter the filter tube.
Via an hose, which slides through the hollow rod, this water can be pumped up
. The passage in the hollow rod is 12 mm.
With help of the foot valve pump S-60
, water can be pumped up
from a depth of up to 20 m
After samples are taken from one depth, the sampler can be driven further in
Efficient applications are the determination of contaminations and their spreading, as well as for soil survey tests.
Water sampler DP 32/42
System with external filter:
Through an external filter, water flows into the sampling device. The hose is lowered through the hollow rod and water can be pumped up.
System with internal filter:
The closed system is driven into the depth of investigation. Then the ejection rod with inner extension rod is inserted into the hollow rod. The lost probing cone is ejected and the internal filter is extended into the groundwater. Following sampling the water can be pumped out again.
Water sampler DP 36/48
This water sampler is available with external or internal
filter system. Differences to the water sampler DP 32/42 are the larger sized
probing rod and the RDS connection
Both water sampling and soil sampling can be performed using RDS connection
and associated probing equipment. One probing rod can be used for both applications
Water sampler PVC glass
An easy, quick and reuseable
system to take water samples
from wells and observation pipes.
Membrane pump OD 25 mm
Sampling of liquids from open water, wells and observation pipes
The membrane pump made of PVC glass is lowered to the investigation depth. After immersion of the pump, water enters through the valve into the hose. By moving the hose up and down the water is pumped up.
Furthermore, the membrane pump can be used as a water sampler with a volume of ca. 350 ml
. The valve in the lower part
opens when lowered into the sample fluid and closes when the pump is moved up.
The piston sampler is applied to take soil samples from below groundwater level and for sandy sediment samples. The piston inside the tube is pulled up manually by using a piston rod it generates a negative pressure to retain the soil sample in the tube. The piston also serves to push out the soil sample.
Sediment corer is applied to take soft and muddy sediment samples. The sediment corer is extenable and can be used by hand in shallow shore areas or in deep water.
When lowered the integrated valve opens, no backwater occurs. The sediment corer pierces the ground. When lifted the valve closes. The resulting negative pressure retains the sediment sample in the tube.
Battery peristaltic pump
peristaltic pump for liquids and gases. The peristaltic pump has a flow rate of ca. 0-2,3 l/min
and works up to suction depth of 6-7 m
The flow rate is adjustable.
The fully charged battery lasts up to ca. 8 hours
Hand operated peristaltic pump
peristaltic pump for liquids and gases. Using a crank, it works in an operation depth up to 9 m
The silicone hose is closed by at least one roll. Therefore liquids and gases cannot flow back.
Peristaltic pump SL-10
This peristaltic pump is designed for the „Direct Push (DP)“ procedure
. By a foot valve pump and PE hose, liquids can be pumped up.
The peristaltic pump is connected by a quick-release system
with PE hose ∅ 10 mm. A pump support pin allows to use the peristaltic pump directly with 2“ gauge tubes.
Foot valve pump
In cases where the use of common pumps is not adequate or effective, these foot valve pumps made of stainless steel can be used to pump up groundwater.
The foot valve pump is connected to the hose. When the foot valve pump is immersed in water, water enters the hose. Through an oscillating movement
, water is pumped up.
Escape of volatile organic substances is restricted
to a minimum
Electric contact meter
Electric contact meter allows a quick and easy measurement
of water levels. Used in wells, tanks, drilling holes
and to control pumping tests.
Available with visual
Electric contact meter with plummet diameter 12 mm and 15 mm are also available with frame stand
HDPE filter tubes
threads TR and TRN are not compatible. TRN comes with smaller filter segment and bigger length tolerances. Slot width
is ca. 0,3 mm.
HDPE attachment tubes
Without slots. TRN has bigger length tolerances.
HDPE cone with external thread
For closing gauge tubes.
HDPE caps with internal thread
For closing gauge tubes.
Plug cap with lid
To plug on top of gauge tubes.
For closing gauge tubes. The plug is simply inserted into the gauge tube. Using a hex wrench, the plug is clamped in the gauge tube by the clamp system. No connection thread is required on the tube.
Adapter TR - inch thread
For connecting trapezodial thread with inch thread.
