  SP1 Suction Pump and Accessories


The Waterra SP1 portable suction pump weighs only 7 kg and is powered by the Honda GX series of ultra-small 4-stroke engines. As well as being a general purpose water pump capable of delivering up to 100 litres per minute, the SP1 is also an ideal tool for purging and sampling boreholes at suction depths (up to 7-9m below ground level) in conjunction with inertial pumps.

The inertial pump is used to manually prime the suction pump. The suction pump can then be used to discharge purge water lifted by suction through the inertial pump tubing. Once purging is completed and to avoid cross-contamination, the suction pump is disconnected and samples taken by manual operation of the inertial pump.

Adaptors for use with either High Flow or Standard Inertial Pumps are available.

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)
