Hunter introduces the MP Rotator SR line. SR stands for short radius. Hunter's MP Rotators have revolutionized overhead irrigation by creating a rotating spray that delivers matched precipitation rates, allowing water to absorb into the soil without runoff or waste. With the new MP800SR, that efficiency is now available for short radius zones. The MP800SR delivers water to the 6' - 12' radius (1.8m - 3.5m). The MP800SR has a precipitation rate of 0.8 in/hr (20 mm/hr) with matched precipitation at any arc or radius. When designing and installing irrigation for spaces under 10 feet - think MP800SR
