Waterra portable bladder pumps are designed for field use in the most demanding of environments. Single turn release head and quick change bladders allow for simple bladder changes in the field - and easy decontamination. Custom hose barbs allow the pump to be secured to tubing without the need for tubing clamps.

• Constructed of highest quality 316 stainless steel
For highest quality VOC sampling

• Available as Portable Field Kits
Complete with control unit incorporating built-in 100 psi air compressor

• Easy-to-open housings
No special tools or training required to service the pumps

• Quick-change bladder configuration
Bladders can be easily exchanged without tools by sliding back the Teflon® collars

• Maximum operating depth of 55 metres

• Drop tube intake option
Allows for deeper sampling

• Extra bladders are readily available
Available in Teflon® and Polyethylene for all models

• Skip Bonded (Dual) tubing
In Polyethylene and Teflon® lined Polyethylene for easier tubing management

• Compatible with any Pneumatic Pump Control Unit

• CE rated to meet EU regulatory standards

Every bladder pump system requires the following additional components:
- Tubing (for air supply and sample discharge)
- Tubing Reels (for portable systems).
- A Control Unit (see our ProPlus and Logic control units)
- A Pressurised Air or Gas Supply (built-in or standalone compressors)

Choose Dedicated Bladder Pumps for pumps suited to deeper applications or for longer term dedicated use

For further information on low flow sampling see:
- Groundwater Sampling Methodology
- TROLL 9500 range of water quality equipment for stability monitoring during low flow pumping.

PCU Drawdown Meter

For full quality control and monitoring of low flow sampling, and to ensure the integrity of VOC sampling, the drawdown in water level during pumping should remain less than 100mm below the starting water level. The optional PCU Drawdown Level Meter connects directly into either the PCU ProPlus or PCU LOGIC pump controllers via a plug in socket. The PCU will provide a warning if the water level in the borehole falls beyond this level during sampling.
