  Waterra Inertial Pumps: Standard X System and Accessories


The STDX system uses thicker walled inertial pump tubing. The thicker walled tubing reduces elasticity during use and enables pumping from depths of between 50 and 85 metres in 50mm diameter boreholes. This system should always be used in conjunction with the PowerPack PP1.

Maximum flow rate (under ideal conditions) is between 0.5 and 2 litres per minute.

Normal Operating Parameters
Borehole Diameters 20 to 100mm
Depth of Operation Manual: not applicable
Powered*: 50m to 85m
Pumping Rate Up to 2 l/min
* using PowerPack PP1

For further technical information and applications see:
- Applications Sheet (6 sampling systems, 3 pumping methods)
- Set up and User Guide (field manual, hints & tips)
- Technical Data (physical dimensions & pumping performance)
