Flomatic Corporation introduced the Model 80S6VFD, a 316 stainless steel submersible pump check valve for use with variable-frequecy drive (VFD) controlled pumps.
I met Doc Faison, then owner of this publication, at the National Ground Water Association convention in the fall of 1993. If you attended any of the state or national groundwater industry conventions in the ’90s, you’ll remember Doc. He always wore his signature red blazer and had a camera dangling around his neck looking for a photo op.
Global water technology company Xylem released the CentriPro brand Aquavar pump controller at last month’s National Ground Water Association 2013 Expo in Nashville, Tenn.
In my last several columns, I have written about selecting the proper openings for a water well screen and some popular installation methods. One thing we must do, however, before installing the screen is equip it with the proper fittings. Screens purchased from a manufacturer or supply house are not going to work as is (with a couple of exceptions).
Many of the ideas for my column are inspired by questions I get from readers and friends in the industry. A few weeks ago, someone asked how to wire in a pressure switch with a pump protection device that required a control relay. The pump protector’s internal relay was rated at 10 amps, sufficient for a 1 horsepower, 230 volt pump but not enough to handle his 3 horsepower pump motor directly, so an additional relay was called for.
