Low Flow Sampling with Mini Bladder Pump (MBP)
Application
Low Flow sampling and purging of groundwater
Features and Specifications
- Suitable for 25mm or larger wells (also available for 1/2″ wells under special conditions)
- Stainless Steel or PVC body with Teflon bladder. Bladder’s are re-usable after decontamination
- Controller is needed to manually match pumping rates with well recharge
- Wide range in sizes and capacities. Selection Table shows most commonly used bladder pumps — several other variations in flow rates and depth capacities are possible
- For sampling at depths below 60 meters a drop tube is used
User’s Advantage
- High efficiency designs enable flow rates from 5 mLPM to nearly 2 LPM when used with a precision controller. Large diameter pumps 42mm (1.66″) can yield flow rates up to 7.5 LPM
- Proven performance over decades of field use
