Waterra Inertial Pumps - Manual Range (Foot Valves and Tubing)
The Waterra Inertial Pump is an efficient, reliable and inexpensive pump suitable for purging and sampling groundwater monitoring boreholes. Its simplicity has allowed the system to be adapted to a variety of sizes, making it suitable for numerous applications. It performs well in harsh environments that would ruin other more expensive pumps, and is a great choice as a dedicated sampler in contaminated land investigations to avoid cross-contamination between borehole samples.
Waterra Inertial Pump tubing and foot valves enable pumping from boreholes of 10mm diameter and upwards. 6 tubing sizes are available accompanied by a range of Stainless Steel and Delrin foot valves.
Tubing is manufactured exclusively for Waterra in the UK and is extruded from high quality HDPE (High Density Polyethylene). HDPE is more rigid than LDPE tubing and consequently allows pumping from significantly greater depths without loss of perfomance due to stretching and elasticity.
Tubing and valves are available for sampling from narrow tubes and piezometer pipes through to monitoring boreholes of 200mm diameter.
Manual operation is possible at shallow depths, though the depth and ease of operation can be signifcantly improved by the addition of a mechanical actuator or, if water levels are within suction depth, by the use of the SP1 suction pump .

Typically used in 50mm or 100mm diameter monitoring boreholes, but can also be used to sample from narrower tubes of 25mm diameter. By use of the Powerpack PP1 and thicker walled STDX tubing, it is possible to pump from 85 metres depth in 50mm diameter monitoring boreholes.
The STDX system uses thicker walled inertial pump tubing which reduces elasticity and allows pumping from depths of between 50 and 85 metres in 50mm diameter boreholes.
Typically used for high flow rate pumping in 50 or 100mm diameter monitoring boreholes or for developing or de-silting monitoring boreholes of 50mm diameter.
