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.
Schramm, together with GenNx360 Capital Partners, has acquired Air Drill Hammers and Bits Pty Ltd., a manufacturer of drilling equipment like hammers and percussion bits for mineral exploration and mining.
Flint & Walling has unveiled a new line of City Pressure Booster Systems. The company says the all-in-one designs of the VP05 and VP10 feature a motor, pressure tank and electronic controller.
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.
Drilling mud—also called drilling fluid—is an essential component of the drilling process. Drilling mud aids in the process of drilling a borehole into the earth. Such holes are drilled for oil and gas extraction, core sampling and a variety of other purposes.
Pinpointing a gas leak isn’t complicated—drill a hole through the pavement, drive the rod through the soil, insert a tester and move to the next spot until you detect the highest level of gas. But determining exactly how you’re going to dig the hole—or, more precisely, with what—can be more complicated. Wrapped into the decision is everything from efficiency to response times to workers’ compensation.
Check valves are an important component of every submersible pump water system. In this article, we will talk about the reasons for using check and the different types of check valves, and show which ones are best for submersible applications. And, finally, we will go over the proper placement of check valves in these systems.
