The Sample Pro 3/4" Portable MicroPurgeR Pump, (Figure 1) is the first pump de- signed specifically to meet the practical needs of sampling small diameter wells: easy to adjust to low-flow purging rates and easy to decontaminate between sampling
Introduction:The MP15 Micro Purge Basics Controller is used to operate QED WellWizard bladder sampling pumps to purge and sample ground water.The MP15, with its self-contained CO2 cylinder (or another compressed gas source connected to the bypass supply fitting) is taken portably from well
The PE bladder provides a leak-tight seal for most applications without the use of clamps; a bladder collar is provided for seal assurance for pump submergences over 50 ft. The cap of the pump twists off for full disassembly of the inlet and outlet check valves and the tubing connection components.
QED sampling bladder pumps fill by hydrostatic pressure. As the inside of the pump's bladder fills with water, the bladder expands. This filling and expanding of the bladder is referred to as the "refill"...
Connect the bladder to the pump head. The PE bladder pushes onto the pump head barb until the bladder fully covers the barb. A clamping collar (white ring) is provided for pump submergences over 50 ft, to assure a leak tight seal of the bladder. Use the clamp collar by putting it over the pump head

Bladder Pump Operation In Low-Submergence QED sampling bladder pumps fill by hydrostatic pressure. As the inside of the pump's bladder fills with water, the bladder expands. This filling and expanding of the bladder is referred to as the "refill" half of the pump cycle. When air pressure is applied to the outside of the bladder, the
