Designed for use in 4-inch and larger wells, the floating stack hydraulic design enables sand and abrasives to pass easily, making it one of the leading sand-handling pumps on the market. The product is ideal for use in irrigation systems, pressure boosting, geothermal systems and fountain applications. The hydraulics increase efficiency up to 13 percent compared to previous models. The stainless steel pump casing is corrosion resistant and has a built-in check valve to prevent drain backflow and hold pressure in the system. The designed impeller and diffuser combinations improve efficiency and performance, allowing for higher pressures per given horsepower — with flows up to 120 GPM and head up to 1400 feet.
