The e-GS 4-inch, high-capacity borehole pump from Goulds Water Technology, a Xylem brand, features a floating-stack hydraulic design that enables sand and abrasives to pass easily. Made for 4-inch and larger wells, the pump has a corrosion-resistant stainless steel casing and built-in check valve to prevent drain backflow and hold pressure.

“Sandy conditions can quickly cause wear and damage to pumps, but the e-GS 4-inch uses GWT’s floating-stack hydraulic design to eliminate contact points. This gives the pump the ability to stand up to sand and other abrasives without damage,” says Shukri Elmazi, product manager at Xylem. “The built-in check valve allows the system to stay pressurized and filled with water. While there is not necessarily a need to add another check valve, Goulds Water Technology recommends one for every 200 feet of vertical pipe.”

Other pump features include polymer impeller material that protects the pump from abrasion and a dual-surface thrust washer that prevents rubbing of components during startup.
“Some municipal water treatment plants use a blend of groundwater and surface water as their source. The e-GS pump is ideal for extracting groundwater and is CSA NSF/ANSI 372-certified for drinking water systems,” he says.

The e-GS Series consists of four hydraulic models (35GS, 45GS, 65GS, 85GS) and can be coupled to 4- or 6-inch NEMA-standard submersible motors for greater flexibility, delivering heads to 1,400 feet and flows to 120 gpm.

“The impeller and diffuser combination was redesigned for greater efficiency, meaning less horsepower is required per stage, allowing for more stages per model,” Elmazi says. “More stages translate to higher pressure and deeper pump sets.” 866/325-4210; www.goulds.com.
