Pumps & 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

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

Whale Purging Pumps

Whale Purging Pumps

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.
