Pumping Equipment
A range of pumping equipment is available from Stuart Well Services to allow efficient sampling of groundwater.
For shallow wells, up to 30 metres in depth, two options are available: Disposable Bailers and Whale Purging Pumps.
Disposable Bailers
These simple bailers are inexpensive and will obtain water samples from almost any depth. A sample of water is collected within the bailer lowered from ground level. When full, a ball valve seals the bailer allowing the water sample to be removed. Depth of sampling is only limited by the length of string.
They are available in 13, 18 and 40 mm diameter sizes and are manufactured from PFAS free, high-density polyethylene.
Whale Purging Pumps
Whale purging pumps provide an easy-to-use economical solution for sampling wells to a depth of 27 metres.
These submersible groundwater sampling pumps are powered by a 12-volt DC power supply (car battery) and come complete with power leads with alligator clips.
- Pre-assembled with heavy gauge cable and alligator clips
- 12V DC Operation (car battery)
- Lower current draw for more efficient performance
- Tough plastic construction
- Flow rates up to 12 litres/minute
- Pumping depth up to approximately 27 metres
- 12mm reinforced hose for riser pipe available

Grundfos SQ, SP Series
Grundfos SQ Compact Submersible Pumps
The SQ pump is Grundfos’ most compact submersible solution for ground water extraction. A mere 3” in diameter, the long, lean pump fits nicely into small boreholes of the same size – or in 4” boreholes that over time have become smaller due to ochre deposits.
The compact design along with key features like dry-running protection and soft start to reduce wear on the motor makes the SQ pump one of the most reliable choices for submersible operation.
Grundfos SP Submersible Borehole Pumps
Grundfos SP are submersible borehole pumps, designed for pumping groundwater. Grundfos SP are all stainless-steel pumps, and they are available in 3 material grades. The pumps are suitable for boreholes in sizes ranging from 4" over 6" and 8" to 10". The motor sizes for the pumps are available in 0.37-250 kW.
