Pumps and 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.

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 40mm diameter and 18mm diameter sizes and are manufactured from high-density polyethylene.

Whale Purging Pumps provide an easy to use economical solution for sampling wells to a depth of 27 metres.
The diameter of the pump is 40mm and is ideal for use in larger monitoring wells.

The pumps are powered by a 12-volt DC power supply (car battery) and come complete with power leads with alligator clips.
Three versions are available - the Whale Mini Purger, which will obtain samples from 9 metres below ground level and the Whale Super Purger for wells up to 18 metres in depths, whilst the Mega Purger is 27 metres below ground level.

Key Features Include:

• 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 3.5 GPM (US)
• Pumping depth up to approximately 30 metres
• 12mm reinforced hose for riser pipe available

When ground water levels exceed 20 metres the Whale P series pumps are particularly suitable allowing sample taking to a range of 27 metres, easy to operate only needing a 12v power source. With these pumps an end user has the ability to sample up to 15 l/min. Recommended by us we can advise on the best unit for your job.

Grundfos SQ Compact Submersible Pumps

The SQ pump is Grundfos’ most compact submersiblesolution 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 dryrunning protection and soft start to reduce wear on motor makes the SQ pump one of the most reliablechoices for submersible operation.
