Bladder Pump for Low Flow Sampling

Low flow sampling bladder pump. A bladder pump is a non-contact, pneumatically operated, positive displacement pump that uses compressed air. It consists of a casing that encloses a flexible bladder made of PTFE or polyethylene. A screen is placed under the bladder to filter out any material that may interfere with the check valves. Bladder pumps are powered by air compressors, compressed air, or nitrogen tanks.
