VFD pump check valves
Flomatic Corporation has introduced its Model 80S6CL-VFD patent-pending submersible pump check valve for use with variable-frequency drive (VFD) control submersible pumps.
Standard check valves will “chatter” and be noisy when a VFD goes to low flow, causing premature wear and eventual failure. These unique valves are designed to minimize flow losses and hydraulic shocks in the pumping system. The valve has a 316 stainless steel body that incorporates North American Specialty Products-patented groove lock type pipe connections called Certa-Lok to support deep-set pumps. An exclusive stainless steel guided poppet system ensures the valve automatically adjusts noiselessly from high to very low flow rates.
The radiuses of the valve seat allow a self-cleaning “one point swiping action” by the radius-edged custom moulded rubber seal disc, the company said in a press release. All internal parts are made from corrosion-resistant materials and have a high strength durable design.

Heron Instruments offers CSA-certified Interface Meters
Heron Instruments H.0IL Interface Meter is designed to assist you in measuring the interface level between two liquids in the same tank, vessel, well or aquifer.
By using the H.0IL you can get an instant indication of any hydrocarbon in the monitoring well along with the depth of the pollutant film, the company said in a news release. It will also show increases in interface levels in the well so remediation can be started as soon as it is required.
The CSA Intrinsically Safe Certification makes the H.0IL ideal for use in hazardous environments.
The hydrocarbon-resistant Kynar jacketed steel tape is able to withstand harsh contaminants.
Book tells the story of ground water
Ground water authority William M. Alley and science writer Rosemarie Alley have teamed up on a new book that explores issues around ground water and sounds the call to protect the vital resource.
In High and Dry: Meeting the Challenges of the World’s Growing Dependence on Groundwater, the authors explore the growing global population, widespread use of industrial chemicals, climate change and consider the threat these factors pose to ground water.
Ground water depletion and contamination has spread from isolated areas to many countries throughout the world, the authors argue. Drawing on examples from around the world, including case studies in the United States, Canada, Australia, India, and Sub-Saharan Africa, they examine ground water from scientific and socioeconomic perspectives.
The 304-page hardcover book, published by Yale University Press, includes stories of people who are making a difference in protecting this ground water.
