QED Sample Pro 3/4" Bladder Pump

The Sample Pro portable pump combines the unparalleled sample accuracy and high reliability of a bladder pump in an easy-to-use design. It runs cool and can run dry without damage, and can be operated using any QED MicroPurge controller options - 12-volt integral compressor, a Honda-powered gasoline-driven compressor, an external compressed air cylinder, or a lightweight backpack with integral CO2 cylinder. The Sample Pro pump's reliability and low maintenance make it more economical to use. Its twist-open design makes it easy to change the disposable bladder in seconds. The compact 14.75” length fits in a bucket for easy cleaning between uses.

The Sample Pro® Portable Pump is the first pump developed specifically to bring the advantages of low-flow sampling to sites requiring portable pumps. Pneumatic design can be operated with compressed air or compressed gas cylinder for complete portability.
