ST1000 Groundwater Sampling Pump

QED Environmental Systems highlights its Well Wizard ST1000, which provides the high sample accuracy and proven reliability of QED’s Well Wizard dedicated bladder pumps in a smaller diameter format. The sampling device is the heart of every low-flow groundwater monitoring system. This is why the ST1000, which goes deeper than other pumps and has a durable construction, provides tremendous value to organizations with these systems.The ST1000, being 0.80” (20mm) OD, can sample wells as small as 1” diameter at depths over 600 feet (183m), which is far deeper than other small diameter bladder pumps. Further, you can sample wells at almost unlimited depth with its optional drop tube inlet kit. This pump also fits larger wells with partial obstruction. The pump has a 316 stainless steel construction and uses QED’s exclusive DuraFlex PTFS bladder formulation. The pump also uses a QED twin bonded tubing, specifically, HDPE that is either teflon-lined or all teflon. These pneumatic bladder pumps are specifically designed for superior low-flow sampling performance. They operate with a unique, gentle action ideal for low-flow sampling. Their timed on/off cycles of compressed air also alternately squeeze the flexible bladder to displace water out of the pump, and then release it to allow the pump to refill by submergence. This all occurs without creating any disturbance that could affect sample chemistry.
