Direct push water sampler
The direct push (DP) procedure is a cheap alternative to often pretty 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 to 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 for additional groundwater tests. Efficient applications are the determination of contaminations and their spreading, as well as for soil survey tests.

Steel ram filter for water sampler S-9097
These steel ram filters are used to adjust the usage of the water sampler S-9097. For easy cleaning, parts are screwed.

Water sampler DP 32/42
System with external filter: Through an external filter, water flows into the sampler. The hose is lowered through the hollow rod and water can be pumped up.

System with internal filter: The locked system is driven into the depth of investigation. Then the ejector rod is inserted into the hollow bar and ejects the lost probing spike. Afterwards the internal filter is extended into the groundwater and water can be pumped up.

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.

With help of the appropriate equipment both water sampling and soil sampling can be performed with the RDS connection. 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 gauge pipes.

The tube gets filled from below and has a membrane valve with safe closing function.

Membrane pump OD 25 mm
Application: Sampling of liquids from open water, wells and gauge pipes.

The membrane pump made of PVC-glass is lowered to the investigation depth. After immersion into the water, water flows 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.

Vacuum drill
The vacuum drill is suitable for taking soil samples from below groundwater level and for sandy sediment samples.

The integrated piston is pulled up manually and generates a negative pressure to hold the soil sample. The piston also serves to express the soil sample.

Sediment lancing tube
Used for taking soil samples from soft and muddy sediment. The sediment lancing tube is extendable and can be used by hand in shallow riparian zones or in deeper water.

When beeing lowered the integrated valve opens, so no water accumulation exists. The lancing tube pierces in the ground. When lifted the valve closes. The resulting negative pressure holds the soil sample in the lancing tube.

Battery peristaltic pump
Battery operated peristaltic pump for pumping liquids and gases. The peristaltic pump has a flow rate of ca. 0-2,3 l/min and works up to a depth of 6-7 m. The flow rate is adjustable.

The fully charged battery lasts up to ca. 8 hours.
Battery peristaltic pump Catalog page 54

Hand-operated peristaltic pump
Hand-operated peristaltic pump for pumping liquids and gases. It works up to a depth of 9 m. The silicone hose is closed by at least one roller. Therefore liquids and gases can´t flow back.

Peristaltic pump SL-10
This peristaltic pump is designed for the „Direct Push (DP)“-procedure. With help of the foot valve pump and PE hose, liquids can be pumped up from up to 20 m.

The peristaltic pump is connected via a quick-release system to the PE hose ∅ 10 mm. A support pin allows to use the peristaltic pump directly with 2“ gauge tubes.

Foot valve pumps
In cases where conventional pumps can´t be used, these foot valve pumps made of stainless steel can be used.

The foot valve pump is connected to the hose. When lowered into the water, water flows in the hose. By an oscillating movement, water is pumped up. Escape of volatile organic substances is restricted to a minimum.
